SpringSecurity学习总结-3 使用SpringSecurity开发基于表单的登录
一、本章介绍(4-1节内容)
1、SpringSecurity功能介绍
(1)认证（你是谁）
(2)授权（你能干什么）
(3)攻击防护（防止伪造身份）
2、SpringSecurity基本原理
3、实现一个用户名+密码认证
4、实现手机号+短信认证
二、SpringSecurity基本原理(4-2节内容)
1、SpringSecurity表单登录的配置
(1)、新建一个配置类继承WebSecurityConfigurerAdapter
package security.browser.config;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
/**
* WebSecurityConfigurerAdapter是SpringSecurity提供的安全适配器类
*/
@Configuration
public class BrowserSecurityConfig extends WebSecurityConfigurerAdapter {
/**
*
* @param http
* @throws Exception
*/
@Override
protected void configure(HttpSecurity http) throws Exception {
// http.formLogin()//开启表单登录(即对表单登录进行身份认证)
http.httpBasic()//开启SpringSecurity原生的表单登录
.and()
.authorizeRequests()//对请求进行授权(即登录后需要授权)
.anyRequest()//对任何请求
.authenticated();//开启认证
// .anyRequest()
// .authenticated();
// 上面两个方法的意思:对任何请求都需要认证
}
}
http.httpBasic()
http.formLogin()
2、SpringSecurity的基本原理
SpringSecurity最核心的就是一系列的过滤器链。(Filters)
(1)右侧蓝色方块的REST API: 提供服务的各种RestController
左侧绿色的过滤器：只有绿色的过滤器是可以自定义配置的，其他的都不能配置，且存在的位置相对固定。
(2)UsernamePasswordAuthenticationFilter(表单用户密码认证过滤器，即http.formLogin())
检查用户登录时是否有用户名和密码，如果有就用用户名和密码去认证，没有用户名和密码就跳到下一个过滤器来处理。
(3)BasicAuthenticationFilter（基础的认证过滤器，即http.httpBasic()）
检查请求的请求头里是否有Basic开头的authentication相关的信息，如果有，用base64来解码出用户名和密码去登录，如果没有就跳到下一个过滤器来处理。
橘黄色的拦截器（FilterSecurityInterceptor）：
(4)橘黄色的FilterSecurityInterceptor：当请求经过绿色的过滤器后到达此拦截器，它是SpringSecurity过滤链处理后的一个拦截器，它来决定进来的请求能否到右侧蓝色方块的REST API里处理请求的服务里。判断的依据是请求是否满足配置的请求条件，满足就进，不满足就抛出一个不满足条件的异常。
这里体现了filter和interceptor两个的执行顺序，即interceptor在filter后面执行。
(5)深蓝色的ExceptionTranslationFilter过滤器：是用来捕获处理橘黄色FilterSecurityInterceptor抛出的各种异常的。
例如
①：抛出用户名密码不存在的异常则会跳转到表单登录页面(http.formLogin())。
②：抛出BasicAuthenticationFilter相关的异常则会跳转到BasicAuthenticationFilter的登录页面（http.httpBasic()）。
前端请求进入SpringSecurity过滤器链的处理顺序：
以 http.httpBasic() 类型的请求为例:
① 初次访问系统资源:
请求 -》BasicAuthenticationFilter的doFilterInternal()方法 -》ExceptionTranslationFilter的doFilter()方法 -》FilterSecurityInterceptor的invoke()方法 -》ExceptionTranslationFilter的doFilter()方法 -》FilterSecurityInterceptor的invoke()方法 -》到httpBasic的登录弹出页面 。
②登录：
(1)登录时信息填写错误时的请求流程:
请求 -》BasicAuthenticationFilter的doFilterInternal()方法 -》ExceptionTranslationFilter的doFilter()方法 -》FilterSecurityInterceptor的invoke()方法 -》到httpBasic的登录弹出页面
(2)登录信息填写正确时的请求流程:
请求 -》BasicAuthenticationFilter的doFilterInternal()方法 -》ExceptionTranslationFilter的doFilter()方法 -》FilterSecurityInterceptor的invoke()方法 -》REST API(开始处理请求)
三、自定义用户用户认证逻辑(4-3节内容)
1、处理用户信息的获取逻辑(UserDetailsService)
(1)原理： SpringSecurity的用户信息的获取逻辑是封装在UserDetailsService接口的loadUserByUsername()方法中，该方法是根据登录时输入的用户名去数据库查找是否有该用户。
(2)自定义处理用户获取逻辑并实现UserDetailsService
package security.browser;
import lombok.extern.slf4j.Slf4j;
import org.springframework.security.core.authority.AuthorityUtils;
import org.springframework.security.core.userdetails.User;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.core.userdetails.UsernameNotFoundException;
import org.springframework.stereotype.Component;
@Component
@Slf4j
public class MyUserDetailsService implements UserDetailsService {
/**
* 可以@AutowiredDao层接口从而实现根据用户名去查找用户信息
* @param username
* @return
* @throws UsernameNotFoundException
*/
@Override
public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
log.info("用户名: "+username);
//这个User类实现了UserDetails
//密码应该是数据库查询出的密码
//authorities:用户权限的集合,即用来给用户授权
User user = new User(username,"123456", AuthorityUtils.commaSeparatedStringToAuthorityList("admin"));
return user;
}
}
(2)登录测试:
控制台报错:
java.lang.IllegalArgumentException: There is no PasswordEncoder mapped for the id "null"原因：这是因为Spring boot 2.x.x引用的security 依赖是 spring security 5.X版本，此版本需要提供一个PasswordEncorder的实例，否则后台汇报错误
解决办法：
①在继承了WebSecurityConfigurerAdapter类的子类中增加PasswordEncoder类型的Bean
@Bean
public PasswordEncoder passwordEncoder(){
return new BCryptPasswordEncoder();
}②在登录时对密码进行加密
@Override
public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
log.info("用户名: "+username);
String password = myPasswordEncoder.encode("123456");
log.info("密码:"+password);
//这个User类实现了UserDetails
//密码应该是数据库查询出的密码
//authorities:用户权限的集合,即用来给用户授权
User user = new User(username,password, AuthorityUtils.commaSeparatedStringToAuthorityList("admin"));
return user;
}2、处理用户校验逻辑(UserDetails)
(1)密码是否匹配校验：是由SpringSecurity来做，我们只需要取出用户的密码给SpringSecurity，它会拿后台数据库的密码和前端输入的密码进行校验。
(2)其他校验：用户是否冻结、密码是否过期等等。
①UserDetails详解：
package org.springframework.security.core.userdetails;
import java.io.Serializable;
import java.util.Collection;
import org.springframework.security.core.GrantedAuthority;
public interface UserDetails extends Serializable {
//用户的权限信息
Collection getAuthorities();
//用户的密码
String getPassword();
//用户的用户名
String getUsername();
//账户是否过期(true=没有过期,false=已过期)
boolean isAccountNonExpired();
//账户是否锁定(true=没有锁定,false=已锁定)
boolean isAccountNonLocked();
//密码是否过期(true=没有过期,false=已过期)
boolean isCredentialsNonExpired();
//账户是否可用(true=可用,false=不可用),即用户是否被删除了
boolean isEnabled();
}
3、处理密码的加密和解密(PasswordEncoder)
四、SpringSecurity开发基于表单的认证(4-4-1内容)
1、自定义登录页面
(1)在继承了WebSecurityConfigurerAdapter类的子类的configure(HttpSecurity http)方法里的http.formLogin()方法后面加loginPage()方法和.loginProcessingUrl()还有antMatchers("/signIn.html").permitAll()。
http.formLogin()//开启表单登录(即对表单登录进行身份认证)
.loginPage("/signIn.html")//指定登录页面
.loginProcessingUrl("/authentication/form")//让UsernamePasswordAuthenticationFilter能够处理提交的登录请求
// http.httpBasic()//开启SpringSecurity原生的表单登录
.and()
.authorizeRequests()//对请求进行授权(即登录后需要授权)
.antMatchers("/signIn.html").permitAll()//允许signIn.html请求进来,不进行拦截
.anyRequest()//对任何请求
.authenticated();//开启认证(2)在resources文件夹下新建templates文件夹，然后在templates文件夹里新增signIn.html登录页面。
登录
表单登录
(3)新建一个负责页面跳转的Controller类，增加对登录页面跳转的方法。
package security.browser.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
@Controller
public class PageController {
@GetMapping("/signIn.html")
public String loginPage(){
return "signIn.html";
}
}
(4)测试：如果测试登录时能够跳转登录页面，但是提交登录却没有成功，可能是没有对跨域进行处理导致的。
解决方法：在继承了WebSecurityConfigurerAdapter类的子类的configure(HttpSecurity http)方法里的.authenticated()方法后面加上对跨域的处理即可。
http.formLogin()//开启表单登录(即对表单登录进行身份认证)
.loginPage("/signIn.html")//指定登录页面
.loginProcessingUrl("/authentication/form")//处理提交登录的请求
// http.httpBasic()//开启SpringSecurity原生的表单登录
.and()
.authorizeRequests()//对请求进行授权(即登录后需要授权)
.antMatchers("/signIn.html").permitAll()//允许signIn.html请求进来,不进行拦截
.anyRequest()//对任何请求
.authenticated()//开启认证
.and()
.csrf() //跨域请求伪造
.disable();//关闭2、自定义登陆成功处理
(1)处理流程示意图
SpringSecurity会首先来处理请求，如果请求需要身份认证，SpringSecurity会让请求跳转到认证页面(登录页面)，但是在跳转之前SpringSecurity会用HttpSessionRequestCache类把请求的信息缓存到session中，这样在认证页面就能获取到原始的请求信息。
(2)对原来的登录跳转及拦截进行修改
package security.browser.config;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
import org.springframework.security.crypto.password.PasswordEncoder;
import security.core.properties.SecurityProperties;
/**
* WebSecurityConfigurerAdapter是SpringSecurity提供的安全适配器类
*/
@Configuration
public class BrowserSecurityConfig extends WebSecurityConfigurerAdapter {
@Autowired
private SecurityProperties securityProperties;
/**
*
* @param http
* @throws Exception
*/
@Override
protected void configure(HttpSecurity http) throws Exception {
http.formLogin()//开启表单登录(即对表单登录进行身份认证)
.loginPage("/authentication/require")//指定登录页面
.loginProcessingUrl("/authentication/form")//让UsernamePasswordAuthenticationFilter能够处理提交的登录请求
// http.httpBasic()//开启SpringSecurity原生的表单登录
.and()
.authorizeRequests()//对请求进行授权(即登录后需要授权)
.antMatchers("/authentication/require",securityProperties.getBrowser().getLoginPage()).permitAll()//允许signIn.html请求进来,不进行拦截
.anyRequest()//对任何请求
.authenticated()//开启认证
.and()
.csrf() //跨域请求伪造
.disable();//关闭
// .anyRequest()
// .authenticated();
// 上面两个方法的意思:对任何请求都需要认证
}
@Bean
public PasswordEncoder passwordEncoder(){
return new BCryptPasswordEncoder();
}
}
(3)新建一个处理登录跳转的RestController
package security.browser.controller;
import lombok.extern.slf4j.Slf4j;
import org.apache.commons.lang.StringUtils;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.http.HttpStatus;
import org.springframework.security.web.DefaultRedirectStrategy;
import org.springframework.security.web.RedirectStrategy;
import org.springframework.security.web.savedrequest.HttpSessionRequestCache;
import org.springframework.security.web.savedrequest.RequestCache;
import org.springframework.security.web.savedrequest.SavedRequest;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.ResponseStatus;
import org.springframework.web.bind.annotation.RestController;
import security.core.properties.SecurityProperties;
import security.core.support.SimpleResponse;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
@RestController
@Slf4j
public class BrowserSecurityController {
@Autowired
private SecurityProperties securityProperties;
@GetMapping("/properties")
public String properties(){
String properties = securityProperties.getBrowser().getLoginPage();
System.out.println("properties:" + properties);
return properties;
}
/**
* 用来获取请求缓存里的信息，后续用来判断是浏览器端请求还是APP端的请求
*/
private RequestCache requestCache = new HttpSessionRequestCache();
/**
* 负责进行跳转
*/
private RedirectStrategy redirectStrategy = new DefaultRedirectStrategy();
/**
* 当需要身份认证时跳转到这里,状态码是未授权的，即没有登陆
* @return
*/
@GetMapping("/authentication/require")
@ResponseStatus(HttpStatus.UNAUTHORIZED)
public SimpleResponse requireAuthentication(HttpServletRequest request, HttpServletResponse response) throws IOException {
//SavedRequest:具体存有请求信息的类
SavedRequest savedRequest = requestCache.getRequest(request,response);
//如果有请求信息
if(savedRequest != null){
//获取引发请求的url地址
String targetUrl = savedRequest.getRedirectUrl();
log.info("引发跳转的url:"+targetUrl);
String properties = securityProperties.getBrowser().getLoginPage();
log.info("properties:" + properties);
//判断targetUrl是否以.html结尾
if(StringUtils.endsWithIgnoreCase(targetUrl,".html")){
redirectStrategy.sendRedirect(request,response,properties);
}else{
}
}
return new SimpleResponse("访问的服务需要身份认证，请引导用户到登录页面");
}
}
(4)在core模块的新建一个application-browser.properties中添加配置
#自定义配置用于处理不同客户端的登录请求
imooc.security.browser.loginPage = /login/browser-login.html(5)在browser模块新建一个login文件夹，增加一个 browser-login.html
browser页面
browser页面
(6)在core模块新建配置相关的类，用途不同配置项也不同。
①BrowserProperties：封装和浏览器相关的配置项。
②ValidateCodeProperties：封装和验证码相关的配置项。
③Oauth2Properties：Oauth相关的配置项。
④SocialProperties：会话相关的配置项。
⑤SecurityProperties：父配置项，里面封装了针对不同类型的配置子项。
(7)在core模块新建配置类
它（demo模块）读取的是core模块里的application-browser.properties配置。不采用视频中讲解的使用demo模块的配置文件是因为发现core模块里的配置类无法读取demo模块的配置，因此将各个模块的配置文件统一放在了core模块里，目的是方便core模块读取配置文件里的配置信息，而且core是基础模块，其他模块都直接或间接的依赖core模块，所以其他模块在需要使用自己所需的配置文件时，只需要在本模块的application,properties文件里加入 spring.profiles.active= browser 来激活不同配置，这样就能在本模块使用core模块读取的配置信息。
①SecurityProperties配置类
package security.core.properties;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.PropertySource;
import org.springframework.stereotype.Component;
@Component
@PropertySource("classpath:application-browser.properties")
//@PropertySource(value= {"classpath:application-demo.properties","classpath:application-browser.properties"})
@ConfigurationProperties("imooc.security")
public class SecurityProperties {
private BrowserProperties browser = new BrowserProperties();
public BrowserProperties getBrowser() {
return browser;
}
public void setBrowser(BrowserProperties browser) {
this.browser = browser;
}
}
②BrowserProperties配置类
package security.core.properties;
public class BrowserProperties {
/**
* 设置默认的登录页面
*/
private String loginPage = "/signIn.html";
public String getLoginPage() {
return loginPage;
}
public void setLoginPage(String loginPage) {
this.loginPage = loginPage;
}
}
③在browser模块的启动类上加@EnableConfigurationProperties(SecurityProperties.class)
提示：哪一个模块需要使用core模块里的配置类，就需要在那一个模块的启动类上加@EnableConfigurationProperties(SecurityProperties.class)
package security.browser;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.context.properties.EnableConfigurationProperties;
import security.core.properties.SecurityProperties;
@SpringBootApplication
@EnableConfigurationProperties(SecurityProperties.class)
public class BrowserApplication {
public static void main(String[] args) {
SpringApplication.run(BrowserApplication.class, args);
}
}
(8)登陆成功的处理(4-5节内容)
①新建处理登录成功的处理器类并实现AuthenticationSuccessHandler
package security.browser.authentication;
import com.fasterxml.jackson.databind.ObjectMapper;
import lombok.extern.slf4j.Slf4j;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.security.core.Authentication;
import org.springframework.security.web.authentication.AuthenticationSuccessHandler;
import org.springframework.stereotype.Component;
import security.core.support.SimpleResponse;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
/**
* 自定义登陆成功的处理器
*/
@Component("imoocAuthenticationSuccessHandler")
@Slf4j
public class ImoocAuthenticationSuccessHandler implements AuthenticationSuccessHandler {
/**
* 用于将对象转为json类型
*/
@Autowired
private ObjectMapper objectMapper;
/**
* @param request
* @param response
* @param authentication 封装了认证信息，包括请求时的ip、session以及认证通过后UserDeatilsService放回的UserDetails
* @throws IOException
* @throws ServletException
*/
@Override
public void onAuthenticationSuccess(HttpServletRequest request, HttpServletResponse response, Authentication authentication) throws IOException, ServletException {
log.info("登陆成功!");
response.setContentType("application/json;charset=UTF-8");
response.getWriter().write(objectMapper.writeValueAsString(authentication));
}
}
②在browser模块的配置类中加入处理登陆成功的方法
/**
* 自定义的登陆成功的处理器
*/
@Autowired
private AuthenticationSuccessHandler imoocAuthenticationSuccessHandler;
------------------------------------------------------------------------------------------------
http.formLogin()//开启表单登录(即对表单登录进行身份认证)
.loginPage("/authentication/require")//指定登录页面
.loginProcessingUrl("/authentication/form")//让UsernamePasswordAuthenticationFilter能够处理提交的登录请求
.successHandler(imoocAuthenticationSuccessHandler)③修改core模块application-browser.properties中的
#注释掉即可恢复使用原来默认的登录页面
#imooc.security.browser.loginPage = /login/browser-login.html
3、登录失败的处理
与2中的(8)类似
(1)新建处理登录成功的处理器类并实现AuthenticationFailureHandler
package security.browser.authentication;
import com.fasterxml.jackson.databind.ObjectMapper;
import lombok.extern.slf4j.Slf4j;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.http.HttpStatus;
import org.springframework.security.core.AuthenticationException;
import org.springframework.security.web.authentication.AuthenticationFailureHandler;
import org.springframework.stereotype.Component;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
/**
* 自定义登录失败的处理器
*/
@Component("imoocAuthenticationFailureHandler")
@Slf4j
public class ImoocAuthenticationFailureHandler implements AuthenticationFailureHandler {
/**
* 用于将对象转为json类型
*/
@Autowired
private ObjectMapper objectMapper;
/**
* @param request
* @param response
* @param exception 包含认证过程中出现的异常信息
* @throws IOException
* @throws ServletException
*/
@Override
public void onAuthenticationFailure(HttpServletRequest request, HttpServletResponse response, AuthenticationException exception) throws IOException, ServletException {
log.info("登陆失败!");
//登陆失败时返回服务器内部异常
response.setStatus(HttpStatus.INTERNAL_SERVER_ERROR.value());
response.setContentType("application/json;charset=UTF-8");
response.getWriter().write(objectMapper.writeValueAsString(exception));
}
}
(2)在browser模块的配置类中加入处理登陆失败的方法
/**
* 自定义的登陆失败的处理器
*/
@Autowired
private AuthenticationFailureHandler imoocAuthenticationFailureHandler;
----------------------------------------------------------------------------------------------------
http.formLogin()//开启表单登录(即对表单登录进行身份认证)
.loginPage("/authentication/require")//指定登录页面
.loginProcessingUrl("/authentication/form")//让UsernamePasswordAuthenticationFilter能够处理提交的登录请求
.successHandler(imoocAuthenticationSuccessHandler)
.failureHandler(imoocAuthenticationFailureHandler)4、对登陆成功和登陆失败进行改造，使它能处理浏览器和APP端请求
(1)在core模块的properties包中新建一个返回类型的枚举类
package security.core.properties;
/**
* 返回类型的枚举类
*/
public enum LoginType {
/**
* 跳转
*/
REDIRECT,
/**
*返回JSON
*/
JSON
}
(2)在BrowserProperties类加入
/**
* 设置默认返回JSON
*/
private LoginType loginType = LoginType.JSON;
public LoginType getLoginType() {
return loginType;
}
public void setLoginType(LoginType loginType) {
this.loginType = loginType;
}完整代码：
package security.core.properties;
public class BrowserProperties {
/**
* 设置默认的登录页面
*/
private String loginPage = "/signIn.html";
/**
* 设置默认返回JSON
*/
private LoginType loginType = LoginType.JSON;
public String getLoginPage() {
return loginPage;
}
public void setLoginPage(String loginPage) {
this.loginPage = loginPage;
}
public LoginType getLoginType() {
return loginType;
}
public void setLoginType(LoginType loginType) {
this.loginType = loginType;
}
}
(3)改造登录成功的处理器
①让它继承SavedRequestAwareAuthenticationSuccessHandler
(查SavedRequestAwareAuthenticationSuccessHandler继承的父类，一直往上查看,可以发现最终也是实现了AuthenticationSuccessHandler接口。)
package security.browser.authentication;
import com.fasterxml.jackson.databind.ObjectMapper;
import lombok.extern.slf4j.Slf4j;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.security.core.Authentication;
import org.springframework.security.web.authentication.AuthenticationSuccessHandler;
import org.springframework.security.web.authentication.SavedRequestAwareAuthenticationSuccessHandler;
import org.springframework.stereotype.Component;
import security.core.properties.LoginType;
import security.core.properties.SecurityProperties;
import security.core.support.SimpleResponse;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
/**
* 自定义登陆成功的处理器
*/
@Component("imoocAuthenticationSuccessHandler")
@Slf4j
public class ImoocAuthenticationSuccessHandler extends SavedRequestAwareAuthenticationSuccessHandler {
}
②加入SecurityProperties类读取配置
/**
* 用户判断需要返回的类型
*/
@Autowired
private SecurityProperties securityProperties;③在方法里加入判断逻辑
//如果配置的登录方式是JSON
if(LoginType.JSON.equals(securityProperties.getBrowser().getLoginType())){
response.setContentType("application/json;charset=UTF-8");
// String type = authentication.getClass().getSimpleName();
response.getWriter().write(objectMapper.writeValueAsString(authentication));
}else{//调用父类的方法，跳转到index.html页面
super.onAuthenticationSuccess(request,response,authentication);
}完整的代码：
package security.browser.authentication;
import com.fasterxml.jackson.databind.ObjectMapper;
import lombok.extern.slf4j.Slf4j;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.security.core.Authentication;
import org.springframework.security.web.authentication.AuthenticationSuccessHandler;
import org.springframework.security.web.authentication.SavedRequestAwareAuthenticationSuccessHandler;
import org.springframework.stereotype.Component;
import security.core.properties.LoginType;
import security.core.properties.SecurityProperties;
import security.core.support.SimpleResponse;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
/**
* 自定义登陆成功的处理器
*/
@Component("imoocAuthenticationSuccessHandler")
@Slf4j
public class ImoocAuthenticationSuccessHandler extends SavedRequestAwareAuthenticationSuccessHandler {
/**
* 用于将对象转为json类型
*/
@Autowired
private ObjectMapper objectMapper;
/**
* 用户判断需要返回的类型
*/
@Autowired
private SecurityProperties securityProperties;
/**
* @param request
* @param response
* @param authentication 封装了认证信息，包括请求时的ip、session以及认证通过后UserDeatilsService放回的UserDetails
* @throws IOException
* @throws ServletException
*/
@Override
public void onAuthenticationSuccess(HttpServletRequest request, HttpServletResponse response, Authentication authentication) throws IOException, ServletException {
log.info("登陆成功!");
//如果配置的返回类型是JSON
if(LoginType.JSON.equals(securityProperties.getBrowser().getLoginType())){
response.setContentType("application/json;charset=UTF-8");
// String type = authentication.getClass().getSimpleName();
response.getWriter().write(objectMapper.writeValueAsString(authentication));
}else{//调用父类的方法，跳转到index.html页面
super.onAuthenticationSuccess(request,response,authentication);
}
}
}
(4)在core模块的 application-browser.properties 配置文件中加入配置
imooc.security.browser.loginType = REDIRECT则启用REDIRECT类型，即重定向到index.html页面；如果不配置则使用JSON类型。需要特别注意的是使用时默认是JSON类型，如果在配置文件中改成了REDIRECT，则返回的信息会不同。
(5)新建在templates文件夹下index.html页面
(6)新建一个负责页面跳转的控制器类，加入处理url为index.html的跳转请求。
@GetMapping("/index.html")
public String index(){
return "/index.html";
}以上就完成了对登陆成功的处理根据类型的返回情况。
登录失败的处理：
(1)登录失败的处理器继承SimpleUrlAuthenticationFailureHandler
(查看SimpleUrlAuthenticationFailureHandler的信息，可以发现它也实现了AuthenticationFailureHandler。)
package security.browser.authentication;
import com.fasterxml.jackson.databind.ObjectMapper;
import lombok.extern.slf4j.Slf4j;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.http.HttpStatus;
import org.springframework.security.core.AuthenticationException;
import org.springframework.security.web.authentication.AuthenticationFailureHandler;
import org.springframework.security.web.authentication.SimpleUrlAuthenticationFailureHandler;
import org.springframework.stereotype.Component;
import security.core.properties.LoginType;
import security.core.properties.SecurityProperties;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
/**
* 自定义登录失败的处理器
*/
@Component("imoocAuthenticationFailureHandler")
@Slf4j
public class ImoocAuthenticationFailureHandler extends SimpleUrlAuthenticationFailureHandler {
}(2)在方法里加入判断类型的逻辑
//如果配置的返回类型是JSON
if(LoginType.JSON.equals(securityProperties.getBrowser().getLoginType())){
//登陆失败时返回服务器内部异常
response.setStatus(HttpStatus.INTERNAL_SERVER_ERROR.value());
response.setContentType("application/json;charset=UTF-8");
//改为只返回错误信息
response.getWriter().write(objectMapper.writeValueAsString(new SimpleResponse(exception.getMessage())));
}else{
super.onAuthenticationFailure(request,response,exception);
}完整代码：
package security.browser.authentication;
import com.fasterxml.jackson.databind.ObjectMapper;
import lombok.extern.slf4j.Slf4j;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.http.HttpStatus;
import org.springframework.security.core.AuthenticationException;
import org.springframework.security.web.authentication.AuthenticationFailureHandler;
import org.springframework.security.web.authentication.SimpleUrlAuthenticationFailureHandler;
import org.springframework.stereotype.Component;
import security.core.properties.LoginType;
import security.core.properties.SecurityProperties;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
/**
* 自定义登录失败的处理器
*/
@Component("imoocAuthenticationFailureHandler")
@Slf4j
public class ImoocAuthenticationFailureHandler extends SimpleUrlAuthenticationFailureHandler {
/**
* 用于将对象转为json类型
*/
@Autowired
private ObjectMapper objectMapper;
/**
* 用户判断需要返回的类型
*/
@Autowired
private SecurityProperties securityProperties;
/**
* @param request
* @param response
* @param exception 包含认证过程中出现的异常信息
* @throws IOException
* @throws ServletException
*/
@Override
public void onAuthenticationFailure(HttpServletRequest request, HttpServletResponse response, AuthenticationException exception) throws IOException, ServletException {
log.info("登陆失败!");
//如果配置的返回类型是JSON
if(LoginType.JSON.equals(securityProperties.getBrowser().getLoginType())){
//登陆失败时返回服务器内部异常
response.setStatus(HttpStatus.INTERNAL_SERVER_ERROR.value());
response.setContentType("application/json;charset=UTF-8");
response.getWriter().write(objectMapper.writeValueAsString(exception));
}else{
super.onAuthenticationFailure(request,response,exception);
}
}
}
五、认证流程源码级详解(4-6节内容)
六、图片验证码
需要注意各个类所在的模块。
1、开发生成图形验证码的接口
(1)根据随机数生成一个图片，下面是工具类 (祖传代码，亲测可用，哈哈哈)
package security.core.validateCode;
import java.awt.*;
import java.awt.image.BufferedImage;
import java.util.HashMap;
import java.util.Map;
import java.util.Random;
/**
* 随机生成验证码的工具类
*/
public class ImageCodeUtil {
//CodeUtils mCodeUtils 属性 和 CodeUtils getInstance()方法可去除,若要去除,则generateCodeAndPic()应该声明成静态方,即用static修饰,调用的时候通过类名直接调用
private static ImageCodeUtil imageCodeUtils;
public static ImageCodeUtil getInstance() {
if(imageCodeUtils == null) {
imageCodeUtils = new ImageCodeUtil();
}
return imageCodeUtils;
}
/**
* 定义图片的width
*/
private static int width = 115;
/**
* 定义图片的height
*/
private static int height = 34;
/**
* 验证码的长度 这里是6位
*/
private static final int DEFAULT_CODE_LENGTH = 6;
/**
* 生成的验证码
*/
private String randomString;

// 存放验证码

// 存放生成的验证码BufferedImage对象
map.put("codePic", bufferedImage);
return map;
}
}
(2)开发处理前台获取验证码请求的处理器，并把随机数存到Session中
package security.browser.controller;
import lombok.extern.slf4j.Slf4j;
import org.springframework.social.connect.web.HttpSessionSessionStrategy;
import org.springframework.social.connect.web.SessionStrategy;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.context.request.ServletWebRequest;
import security.core.validateCode.ImageCodeUtil;
import javax.imageio.ImageIO;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.awt.image.RenderedImage;
import java.io.IOException;
import java.util.Map;
@RestController
@Slf4j
public class ValidateCodeController {
/**
* 图形验证码的key
*/
private static final String SESSION_IMAGE_CODE_KEY = "SESSION_IMAGE_CODE_KEY";
/**
* social工具，用于存储Session信息
*/
private SessionStrategy sessionStrategy = new HttpSessionSessionStrategy();
/**
* 提供图片验证码
* @param request
* @param response
* @throws IOException
*/
@GetMapping("/code/image")
public void createImageCode(HttpServletRequest request, HttpServletResponse response) throws IOException {
//1、生成验证码
Map imageCodeMap = ImageCodeUtil.getInstance().generateCodeAndPic();
log.info("图形验证码："+imageCodeMap.get("imageCode"));
//2、存入到Session中
sessionStrategy.setAttribute(new ServletWebRequest(request),SESSION_IMAGE_CODE_KEY,imageCodeMap.get("imageCode"));
//3、写入到响应中（response)
ImageIO.write((RenderedImage) imageCodeMap.get("codePic"),"JPEG",response.getOutputStream());
}
}
(3)将生成的图片写到接口的响应中，显示到页面上，即（2）中的步骤3。
(4)在配置类中加入允许访问图片验证吗的url
.antMatchers("/authentication/require",securityProperties.getBrowser().getLoginPage()
,"/code/image").permitAll()//允许signIn.html请求进来,不进行拦截(5)在负责登录的HTML页面中加入
图形验证码:
输入框中name="imageCode"，是验证码的参数名称，后台就是使用imageCode来从request中获取前台输入的验证码。
完整的signIn.html代码：
登录
表单登录
2、在认证流程中加入图形验证码校验。
①新建一个验证码的过滤器类 ValidateCodeFilter 并继承 OncePerRequestFilter，OncePerRequestFilter类是在所有过滤器前执行的过滤器，即过滤器链上的前置过滤器。
package security.core.validateCode;
import org.springframework.web.filter.OncePerRequestFilter;
import javax.servlet.FilterChain;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
/**
* 在处理请求之前过滤，且只过滤一次
*/
public class ValidateCodeFilter extends OncePerRequestFilter {
@Override
protected void doFilterInternal(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, FilterChain filterChain) throws ServletException, IOException {
}
}②在 doFilterInternal() 方法中对提交的登录请求进行过滤，主要的目的是为了校验验证码。特别需要注意的是 filterChain.doFilter(request,response); 不要写错位置，它是在if()代码块后面，如果if()代码块里有异常则不会再执行filterChain.doFilter(request,response); ，直接返回异常信息；如果没有出现异常需要继续调用过滤器链上的其他过滤器，主要是调用后面的UsernamePasswordAuthenticationFilter过滤器。
完整代码：
package security.core.validateCode;
import org.apache.commons.lang.StringUtils;
import org.springframework.security.web.authentication.AuthenticationFailureHandler;
import org.springframework.social.connect.web.HttpSessionSessionStrategy;
import org.springframework.social.connect.web.SessionStrategy;
import org.springframework.web.bind.ServletRequestUtils;
import org.springframework.web.context.request.ServletWebRequest;
import org.springframework.web.filter.OncePerRequestFilter;
import javax.servlet.FilterChain;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
/**
* 在处理请求之前过滤，且只过滤一次
*/
public class ValidateCodeFilter extends OncePerRequestFilter {
/**
* 登陆失败的处理器
*/
private AuthenticationFailureHandler authenticationFailureHandler;
/**
* 图形验证码的key
*/
private static final String SESSION_IMAGE_CODE_KEY = "SESSION_IMAGE_CODE_KEY";
/**
* 存储了Session信息
*/
private SessionStrategy sessionStrategy = new HttpSessionSessionStrategy();
/**
* 对图形验证码进行校验
* @param request
* @param response
* @param filterChain
* @throws ServletException
* @throws IOException
*/
@Override
protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain filterChain) throws ServletException, IOException {
//如果提交的请求url是/authentication/form，且是POST请求
if(StringUtils.equals("/authentication/form",request.getRequestURI())
&& StringUtils.equalsIgnoreCase(request.getMethod(),"post")){
try {
//从Session中获取参数，需要以ServletWebRequest为参数
validate(new ServletWebRequest(request));
}catch (ValidateCodeException exception){
//如果捕获异常就使用authenticationFailureHandler把错误信息返回回去
authenticationFailureHandler.onAuthenticationFailure(request,response,exception);
return;//如果抛出异常了就不再继续走下面的过滤器了
}
}
//校验完图形验证码后调用下一个过滤器
filterChain.doFilter(request,response);
}
/**
* 图形验证码校验的具体方法
* @param request
*/
public void validate(ServletWebRequest request) throws ServletException{
//Session中取出，即后台存储的验证码
String sessionImageCode = (String)sessionStrategy.getAttribute(request,SESSION_IMAGE_CODE_KEY);
//从请求中取出
String requestImageCode = ServletRequestUtils.getStringParameter(request.getRequest(),"imageCode");
if(StringUtils.isBlank(requestImageCode)){
throw new ValidateCodeException("验证码不能为空");
}
if(StringUtils.isBlank(sessionImageCode)){
throw new ValidateCodeException("验证码不存在");
}
if(!StringUtils.equalsIgnoreCase(sessionImageCode,requestImageCode)){
throw new ValidateCodeException("验证码不匹配");
}
//如果没有出现以上的异常则验证完后删除session中存储的验证码
sessionStrategy.removeAttribute(request,SESSION_IMAGE_CODE_KEY);
}
public AuthenticationFailureHandler getAuthenticationFailureHandler() {
return authenticationFailureHandler;
}
public void setAuthenticationFailureHandler(AuthenticationFailureHandler authenticationFailureHandler) {
this.authenticationFailureHandler = authenticationFailureHandler;
}
}
③验证码校验中异常的处理。
package security.core.validateCode;
import org.springframework.security.core.AuthenticationException;
import java.io.Serializable;
/**
* AuthenticationException:是security校验过程中出现异常的父类
*/
public class ValidateCodeException extends AuthenticationException implements Serializable {
private static final long serialVersionUID = -2799288346535627988L;
/**
* @param detail A possibly null string containing details of the exception.
* @see Throwable#getMessage
*/
public ValidateCodeException(String detail) {
super(detail);
}
}
④将验证码的过滤器加到过滤器链上。在 BrowserSecurityConfig 配置类的 configure(HttpSecurity http)方法中加入验证码的过滤器，放到 UsernamePasswordAuthenticationFilter 前。
以下为部分代码：
/**
* @param http
* @throws Exception
*/
@Override
protected void configure(HttpSecurity http) throws Exception {
//加入图片验证码的前置校验过滤器
ValidateCodeFilter validateCodeFilter = new ValidateCodeFilter();
validateCodeFilter.setAuthenticationFailureHandler(imoocAuthenticationFailureHandler);
http.addFilterBefore(validateCodeFilter, UsernamePasswordAuthenticationFilter.class)
.formLogin()//开启表单登录(即对表单登录进行身份认证)
// http.formLogin()//开启表单登录(即对表单登录进行身份认证)
.loginPage("/authentication/require")//指定登录页面
.loginProcessingUrl("/authentication/form")//让UsernamePasswordAuthenticationFilter能够处理提交的登录请求
.successHandler(imoocAuthenticationSuccessHandler)
.failureHandler(imoocAuthenticationFailureHandler)完整代码：
package security.browser.config;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
import org.springframework.security.crypto.password.PasswordEncoder;
import org.springframework.security.web.authentication.AuthenticationFailureHandler;
import org.springframework.security.web.authentication.AuthenticationSuccessHandler;
import org.springframework.security.web.authentication.UsernamePasswordAuthenticationFilter;
import security.core.properties.SecurityProperties;
import security.core.validateCode.ValidateCodeFilter;
/**
* WebSecurityConfigurerAdapter是SpringSecurity提供的安全适配器类
*/
@Configuration
public class BrowserSecurityConfig extends WebSecurityConfigurerAdapter {
/**
* 读取配置信息
*/
@Autowired
private SecurityProperties securityProperties;
/**
* 自定义的登陆成功的处理器
*/
@Autowired
private AuthenticationSuccessHandler imoocAuthenticationSuccessHandler;
/**
* 自定义的登陆失败的处理器
*/
@Autowired
private AuthenticationFailureHandler imoocAuthenticationFailureHandler;
/**
*
* @param http
* @throws Exception
*/
@Override
protected void configure(HttpSecurity http) throws Exception {
//加入图片验证码的前置校验过滤器
ValidateCodeFilter validateCodeFilter = new ValidateCodeFilter();
validateCodeFilter.setAuthenticationFailureHandler(imoocAuthenticationFailureHandler);
http.addFilterBefore(validateCodeFilter, UsernamePasswordAuthenticationFilter.class)
.formLogin()//开启表单登录(即对表单登录进行身份认证)
// http.formLogin()//开启表单登录(即对表单登录进行身份认证)
.loginPage("/authentication/require")//指定登录页面
.loginProcessingUrl("/authentication/form")//让UsernamePasswordAuthenticationFilter能够处理提交的登录请求
.successHandler(imoocAuthenticationSuccessHandler)
.failureHandler(imoocAuthenticationFailureHandler)
// http.httpBasic()//开启SpringSecurity原生的表单登录
.and()
.authorizeRequests()//对请求进行授权(即登录后需要授权)
.antMatchers("/authentication/require",securityProperties.getBrowser().getLoginPage(),"/code/image").permitAll()//允许signIn.html请求进来,不进行拦截
.anyRequest()//对任何请求
.authenticated()//开启认证
.and()
.csrf() //跨域请求伪造
.disable();//关闭
// .anyRequest()
// .authenticated();
// 上面两个方法的意思:对任何请求都需要认证
}
@Bean
public PasswordEncoder passwordEncoder(){
return new BCryptPasswordEncoder();
}
}
完成验证码所有代码。
再次强调要注意application-browser.properties配置文件中 imooc.security.browser.loginType = JSON 还是 REDIRECT，它会影响返回的结果。
3、重构图形验证码接口（目的是为了可重用）
(1)验证码基本参数可配置
即验证码和验证码图片之间的宽度、高度，验证码的长度等可配置
这里只有两级，即应用级配置和默认配置，对于请求级 的配置暂时舍弃。
① 在core模块的 properties包中新建 ImageCodeProperties 类，里面的数值即为默认配置。
package security.core.properties;
/**
* 图形验证码的默认配置类
*/
public class ImageCodeProperties {
/**
* 验证码图片的宽度 115位默宽度
*/
private int width = 115;
/**
* 验证码图片的高度 34为默认高度
*/
private int height = 34;
/**
* 验证码的长度 6为默认长度
*/
private int DEFAULT_CODE_LENGTH = 6;
public int getWidth() {
return width;
}
public void setWidth(int width) {
this.width = width;
}
public int getHeight() {
return height;
}
public void setHeight(int height) {
this.height = height;
}
public int getDEFAULT_CODE_LENGTH() {
return DEFAULT_CODE_LENGTH;
}
public void setDEFAULT_CODE_LENGTH(int DEFAULT_CODE_LENGTH) {
this.DEFAULT_CODE_LENGTH = DEFAULT_CODE_LENGTH;
}
}
② 在core模块的 properties包中新建 ValidateCodeProperties 类 (专门负责验证码相关的配置)
package security.core.validateCode;
import security.core.properties.ImageCodeProperties;
/**
* 验证码相关的配置类（包含图片验证码、短信验证码等）
*/
public class ValidateCodeProperties {
private ImageCodeProperties image = new ImageCodeProperties();
public ImageCodeProperties getImage() {
return image;
}
public void setImage(ImageCodeProperties image) {
this.image = image;
}
}
③ 在 SecurityProperties 中加入 ValidateCodeProperties
package security.core.properties;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.PropertySource;
import org.springframework.stereotype.Component;
import security.core.validateCode.ValidateCodeProperties;
@Component
@PropertySource("classpath:application-browser.properties")
//@PropertySource(value= {"classpath:application-demo.properties","classpath:application-browser.properties"})
@ConfigurationProperties("imooc.security")
public class SecurityProperties {
/**
* 浏览器相关的配置
*/
private BrowserProperties browser = new BrowserProperties();
/**
* 验证码相关的配置
*/
private ValidateCodeProperties code = new ValidateCodeProperties();
public BrowserProperties getBrowser() {
return browser;
}
public void setBrowser(BrowserProperties browser) {
this.browser = browser;
}
public ValidateCodeProperties getCode() {
return code;
}
public void setCode(ValidateCodeProperties code) {
this.code = code;
}
}
④ 在application-browser.properties中加入应用级的配置，只要在 application-browser.properties 配置了验证码的参数信息，在使用时就会覆盖 ImageCodeProperties 默认的配置。
imooc.security.code.image.width = 120
imooc.security.code.image.height = 40
imooc.security.code.image.DEFAULT_CODE_LENGTH = 5⑤修改 ImageCodeUtil 中的配置，让它通过读取参数信息来动态配置验证码
需要修改的地方
(1) 注释掉原有的 width、height、DEFAULT_CODE_LENGTH配置
(2) 将generateCodeAndPic() 改为 generateCodeAndPic(int width,int height,int DEFAULT_CODE_LENGTH) 来接收参数
(3) 将getRandomString() 改为 getRandomString(int DEFAULT_CODE_LENGTH)

⑥ 改造ValidateCodeController
(1)加入SecurityProperties配置类
/**
* 使用配置文件里的验证码参数配置
*/
@Autowired
private SecurityProperties securityProperties;(2)将读入的配置传到ImageCodeUtil的 generateCodeAndPic(int width,int height,int DEFAULT_CODE_LENGTH)中。
int width = securityProperties.getCode().getImage().getWidth();
int height = securityProperties.getCode().getImage().getHeight();
int codeLength = securityProperties.getCode().getImage().getDEFAULT_CODE_LENGTH();
//1、生成验证码

log.info("验证码："+codeMap.get("imageCode"));
//2、存入到Session中
sessionStrategy.setAttribute(new ServletWebRequest(request),SESSION_KEY,codeMap.get("imageCode"));
//3、写入到响应中（response)
ImageIO.write((RenderedImage) codeMap.get("codePic"),"JPEG",response.getOutputStream());
}
}
(2)验证码拦截的接口可配置
即拦截图形验证码的过滤器中表单提交的url地址可配置
① 在 ImageCodeProperties 中加入 url 的参数
/**
* 验证码拦截的接口可配置,用于对逗号隔开的url进行拦截
*/
private String url;
public String getUrl() {
return url;
}
public void setUrl(String url) {
this.url = url;
}② 在 application-browser.properties配置文件中加入配置 url 集合
#验证码拦截的接口可配置(用于对图形验证码的校验，即遇到该url才进行图形验证码校验)
imooc.security.code.image.url = /user,/user/*③ 对 ValidateCodeFilter 进行改造
（1）再加上实现 InitializingBean 主要是使用 InitializingBean 类中的 afterPropertiesSet() 方法
这里对InitializingBean 增加一些个人的理解，实现 InitializingBean 的目的是使用 afterPropertiesSet()在 ValidateCodeFilter 类初始化的时候就进行 url 的添加此处使用并没有特别其他的含义。
（2）加入一些相关属性
/**
* 用于存储需要拦截的url地址集合
*/
private Set urls = new HashSet<>();
/**
* 使用配置文件里配置的拦截url地址
*/
private SecurityProperties securityProperties;
/**
* 用于对url地址进行匹配判断
*/
private AntPathMatcher antPathMatcher = new AntPathMatcher();
public SecurityProperties getSecurityProperties() {
return securityProperties;
}
public void setSecurityProperties(SecurityProperties securityProperties) {
this.securityProperties = securityProperties;
} （3）afterPropertiesSet() 方法中的处理逻辑
/**
* 用户将配置文件中配置的url集合遍历后放到urls集合中
* @throws ServletException
*/
@Override
public void afterPropertiesSet() throws ServletException {
super.afterPropertiesSet();
String[] configUrls = StringUtils.split(securityProperties.getCode().getImage().getUrl(),",");
for(String configUrl : configUrls){
urls.add(configUrl);
}
//把提交表单的登录请求也加到url集合中
urls.add("/authentication/form");
}（4）修改 doFilterInternal() 方法
/**
* 对图形验证码进行校验
* @param request
* @param response
* @param filterChain
* @throws ServletException
* @throws IOException
*/
@Override
protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain filterChain) throws ServletException, IOException {
//如果提交的请求url是/authentication/form，且是POST请求
// if(StringUtils.equals("/authentication/form",request.getRequestURI())
// && StringUtils.equalsIgnoreCase(request.getMethod(),"post")){
//用于对urls集合中所有的url进行遍历判断
boolean action = false;
for(String url : urls){
//如果请求中的url和我们配置拦截的url一致，action = true；
if(antPathMatcher.match(url,request.getRequestURI())){
action = true;
}
}
if(action){
try {
//从Session中获取参数，需要以ServletWebRequest为参数
validate(new ServletWebRequest(request));
}catch (ValidateCodeException exception){
//如果捕获异常就使用authenticationFailureHandler把错误信息返回回去
authenticationFailureHandler.onAuthenticationFailure(request,response,exception);
return;//如果抛出异常了就不再继续走下面的过滤器了
}
}
//校验完图形验证码后调用下一个过滤器
filterChain.doFilter(request,response);

（5）给 BrowserSecurityConfig 的 configure(HttpSecurity http) 方法中的 ValidateCodeFilter 对象增加设置
//加入图片验证码的前置校验过滤器
ValidateCodeFilter validateCodeFilter = new ValidateCodeFilter();
validateCodeFilter.setAuthenticationFailureHandler(imoocAuthenticationFailureHandler);
//设置可配置的拦截url
validateCodeFilter.setSecurityProperties(securityProperties);
validateCodeFilter.afterPropertiesSet();(3)验证码的生成逻辑可配置
① 新建一个 ValidateCodeGenerator 接口类，里面添加生成验证码的抽象方法
package security.core.validateCode;
import java.util.Map;
/**
* 负责生成验证码的接口
*/
public interface ValidateCodeGenerator {
/**
* 生成图形验证码的接口方法
* @param width
* @param height
* @param DEFAULT_CODE_LENGTH
* @return
*/
Map generateCodeAndPic(int width,int height,int DEFAULT_CODE_LENGTH);
}
②新建一个 ImageCodeGenerator 来实现 ValidateCodeGenerator 接口里的生成图形验证码的方法
package security.core.validateCode;
import org.springframework.stereotype.Component;
import java.util.Map;
/**
* 负责生成图形验证码的实现类
*/
public class ImageCodeGenerator implements ValidateCodeGenerator{
/**
* 生成图形验证码的方法
* @param width
* @param height
* @param DEFAULT_CODE_LENGTH
* @return
*/
@Override
public Map generateCodeAndPic(int width, int height, int DEFAULT_CODE_LENGTH) {
Map codeMap = ImageCodeUtil.getInstance().generateCodeAndPic(width,height,DEFAULT_CODE_LENGTH);
return codeMap;
}
}
③ 在 BrowserSecurityConfig 加入ValidateCodeGenerator 接口的 Bean
@Bean
public ValidateCodeGenerator imageCodeGenerator(){
return new ImageCodeGenerator();
}④ 修改 ValidateCodeController 中的代码
（1）加入ValidateCodeGenerator
@Autowired
private ValidateCodeGenerator imageCodeGenerator;（2）修改生成验证码的接口方法
//1、生成验证码
// Map codeMap = ImageCodeUtil.getInstance().generateCodeAndPic(width,height,codeLength);
//动态配置的验证码生成逻辑
Map codeMap = imageCodeGenerator.generateCodeAndPic(width,height,codeLength); 完整的代码：
package security.browser.controller;
import lombok.extern.slf4j.Slf4j;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.social.connect.web.HttpSessionSessionStrategy;
import org.springframework.social.connect.web.SessionStrategy;

private static final String SESSION_KEY = "SESSION_IMAGE_CODE_KEY";
/**

*/
private SessionStrategy sessionStrategy = new HttpSessionSessionStrategy();
/**

@Autowired
private SecurityProperties securityProperties;
@Autowired
private ValidateCodeGenerator imageCodeGenerator;
/**

*/
@GetMapping("/code/image")
public void createImageCode(HttpServletRequest request, HttpServletResponse response) throws Exception{
int width = securityProperties.getCode().getImage().getWidth();
int height = securityProperties.getCode().getImage().getHeight();
int codeLength = securityProperties.getCode().getImage().getDEFAULT_CODE_LENGTH();
//1、生成验证码
// Map codeMap = ImageCodeUtil.getInstance().generateCodeAndPic(width,height,codeLength);
//动态配置的验证码生成逻辑
Map codeMap = imageCodeGenerator.generateCodeAndPic(width,height,codeLength);
log.info("验证码："+codeMap.get("imageCode"));
//2、存入到Session中
sessionStrategy.setAttribute(new ServletWebRequest(request),SESSION_KEY,codeMap.get("imageCode"));
//3、写入到响应中（response)
ImageIO.write((RenderedImage) codeMap.get("codePic"),"JPEG",response.getOutputStream());
}
}
七、SpringSecurity的记住我功能
1、记住我功能的基本原理
(1)、表单请求提交后经过UsernamePasswordAuthenticationFilter后，如果验证通过（即验证成功），会去调用RemeberMeService服务，在RemeberMeService类里面有一个TokenRepository()方法。TokenRepository()方法会生成一个token，将这个token存入到浏览器的Cookie中，同时TokenRepository()方法还会将这个Token写入到数据库中，因为记住我功能是在通过UsernamePasswordAuthenticationFilter认证成功之后调用的RemeberMeService服务，所以在存入数据库的时候会将用户名和token存入进去。
(2)、当下次同一个用户再次访问系统的时候，如果系统配置了记住我功能，访问请求会先经过RememberMeAuthenticationFilter过滤器，这个过滤器会去读取cookie中的token，然后交给RemeberMeService，RemeberMeService会用TokenRepository()方法到数据库中去查询这个token在数据库中有没有记录，如果有记录会将username取出来，取出来之后再调用UserDetailsService去获取用户信息，然后将用户信息存入到SecurityContext中去，这样就实现了记住我的功能。
(3)、RemeberMeService的过滤器所处的过滤器链位置
2、记住我功能的具体实现
(1)、signIn.html登录页面添加记住我复选框
注意：name只能设置为：remember-me
记住我
signIn.html页面完整代码：
登录
表单登录
(2)在配置文件中配置使用的数据库，我是配置在了application-browser.properties配置文件中
spring.datasource.type=com.alibaba.druid.pool.DruidDataSource
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.url=jdbc:mysql://localhost:3306/springsecurity?useUnicode=true&characterEncoding=utf8&useSSL=false&useTimezone=true&serverTimezone=GMT%2B8
spring.datasource.username=root
spring.datasource.password=root
(3)在BrowserSecurityConfig配置类中配置PersistentTokenRepository
@Autowired
private DataSource dataSource;
@Autowired
private UserDetailsService userDetailsService;
@Bean
public PersistentTokenRepository persistentTokenRepository(){
JdbcTokenRepositoryImpl tokenRepository = new JdbcTokenRepositoryImpl();
tokenRepository.setDataSource(dataSource);
// tokenRepository.setCreateTableOnStartup(true);
return tokenRepository;
}①、在PersistentTokenRepository类的对象中注入dataSource配置(数据库配置);
②、开启自动新建存储token和用户名的数据表，tokenRepository.setCreateTableOnStartup(true);需要注意的是这个方法只负责创建数据表，如果数据库里已经有相应的数据表了，再在项目中开启自动建表功能会报错。
或者手动在数据库建好相应的数据表，建表语句在JdbcTokenRepositoryImpl类中。
(4)在BrowserProperties类中设置一个默认的记住我的时间，单位是秒(s)，这个也是可以在application-browser.properties配置文件中去配置的。默认我写了360秒(即一小时)
/**
* 记住我
*/
private int rememberMeSecond = 3600;
public int getRememberMeSecond() {
return rememberMeSecond;
}
public void setRememberMeSecond(int rememberMeSecond) {
this.rememberMeSecond = rememberMeSecond;
}(5)在BrowserSecurityConfig配置类中的configure(HttpSecurity http)中配置记住我
http.addFilterBefore(validateCodeFilter, UsernamePasswordAuthenticationFilter.class)
.formLogin()
.loginPage("/authentication/require")
.loginProcessingUrl("/authentication/form")
.successHandler(tinnerAuthentivationSuccessHandler)
.failureHandler(tinnerAuthentivationFailureHandler)
//记住我功能
.and()
.rememberMe()
.tokenRepository(persistentTokenRepository())
.tokenValiditySeconds(securityProperties.getBrowser().getRememberMeSecond())
.userDetailsService(userDetailsService)3、记住我功能SpringSecurity源码解析(略）
八、实现短信验证码登录
1、开发短信验证码接口
8.1.1本次是将短信以及邮件发送服务抽出为一个单独的子模块，使用的是阿里云的短信服务
(1)、新建短信及邮件发送的配置文件msn.properties
###################################### 短信服务 ##################################################
#短信服务 accessKeyId
message.msn.accessKeyId=
#短信服务 accessKeySecret
message.msn.accessKeySecret=
#短信服务 产品名称:云通信短信API产品,开发者无需替换
message.msn.product=Dysmsapi
#短信服务 发送短信的域名
message.msn.domain=dysmsapi.aliyuncs.com
#短信服务 区域Id
message.msn.regionId=
#短信服务 签名
message.msn.signName=
#短信服务 模板
message.msn.templateCode=
#短信服务 模板参数
message.msn.templateParam=code
#短信服务 发送日期 支持30天内记录查询，格式yyyyMMdd
message.msn.dateFormat=yyyyMMdd
#短信服务 服务节点
message.msn.endpointName=
#阿里云短信服务
#用户登录名称
#AccessKey ID ：
#AccessKeySecret：
###################################### 邮件服务 ##################################################
#邮件服务 accessKeyId
message.mail.accessKeyId=
#邮件服务 accessKeySecret
message.mail.accessKeySecret=
#邮件服务 发信地址
message.mail.accountName=
#邮件服务 区域Id
message.mail.regionId=
#邮件服务 发信人昵称
message.mail.sendPersonName=
#邮件服务 取值范围 0~1: 0 为随机账号；1 为发信地址
message.mail.addressType=
#邮件服务 控制台创建的标签
message.mail.tagName=
#邮件服务 回信地址
message.mail.replyToAddress=
#邮件服务 目标地址
message.mail.toAddress=
(2)新建读取配置的类MsnProperties.properties
package imooc.security.msn.properties;
public class MsnProperties {
/**
* accessKeyId
*/
private String accessKeyId;
/**
* accessKeySecret
*/
private String accessKeySecret;
/**
*产品名称:云通信短信API产品,开发者无需替换
*/
private String product;
/**
*发送短信的域名
*/
private String domain;
/**
*区域Id
*/
private String regionId;
/**
*签名
*/
private String signName;
/**
*模板
*/
private String templateCode;
/**
*模板参数
*/
private String templateParam;
/**
*发送日期 支持30天内记录查询，格式yyyyMMdd
*/
private String dateFormat;
/**
*服务节点
*/
private String endpointName;
public String getAccessKeyId() {
return accessKeyId;
}
public void setAccessKeyId(String accessKeyId) {
this.accessKeyId = accessKeyId;
}
public String getAccessKeySecret() {
return accessKeySecret;
}
public void setAccessKeySecret(String accessKeySecret) {
this.accessKeySecret = accessKeySecret;
}
public String getProduct() {
return product;
}
public void setProduct(String product) {
this.product = product;
}
public String getDomain() {
return domain;
}
public void setDomain(String domain) {
this.domain = domain;
}
public String getRegionId() {
return regionId;
}
public void setRegionId(String regionId) {
this.regionId = regionId;
}
public String getSignName() {
return signName;
}
public void setSignName(String signName) {
this.signName = signName;
}
public String getTemplateCode() {
return templateCode;
}
public void setTemplateCode(String templateCode) {
this.templateCode = templateCode;
}
public String getTemplateParam() {
return templateParam;
}
public void setTemplateParam(String templateParam) {
this.templateParam = templateParam;
}
public String getDateFormat() {
return dateFormat;
}
public void setDateFormat(String dateFormat) {
this.dateFormat = dateFormat;
}
public String getEndpointName() {
return endpointName;
}
public void setEndpointName(String endpointName) {
this.endpointName = endpointName;
}
}
(3)、新建信息发送服务的配置属性类MessageProperties.java
package imooc.security.msn.properties;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.PropertySource;
import org.springframework.stereotype.Component;
@Component
@PropertySource("classpath:msn.properties")
@ConfigurationProperties("message")
public class MessageProperties {
private MsnProperties msn = new MsnProperties();
private MailProperties mail = new MailProperties();
public MsnProperties getMsn() {
return msn;
}
public void setMsn(MsnProperties msn) {
this.msn = msn;
}
public MailProperties getMail() {
return mail;
}
public void setMail(MailProperties mail) {
this.mail = mail;
}
}
(4)、新建消息发送的服务MessageService.java ,代码仅供参考
package imooc.security.msn.service;
import com.alibaba.fastjson.JSON;
import com.aliyuncs.CommonRequest;
import com.aliyuncs.CommonResponse;
import com.aliyuncs.DefaultAcsClient;
import com.aliyuncs.IAcsClient;
import com.aliyuncs.dm.model.v20151123.SingleSendMailRequest;
import com.aliyuncs.dm.model.v20151123.SingleSendMailResponse;
import com.aliyuncs.exceptions.ClientException;
import com.aliyuncs.exceptions.ServerException;
import com.aliyuncs.http.MethodType;
import com.aliyuncs.profile.DefaultProfile;
import com.aliyuncs.profile.IClientProfile;
import imooc.security.msn.properties.MessageProperties;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
import org.springframework.web.bind.annotation.GetMapping;
import java.util.HashMap;
import java.util.Map;
@Component
public class MessageService {
/**
* 消息的配置
*/
@Autowired
private MessageProperties messageProperties;
/**
* 短信
* @return
*/
@GetMapping("/msn")
public String sendMsn(int length,String phone) {
//短信发送结果
String regionId = messageProperties.getMsn().getRegionId();
String accessKeyId = messageProperties.getMsn().getAccessKeyId();
String accessSecret = messageProperties.getMsn().getAccessKeySecret();
// String signName = messageProperties.getMsn().getSignName();
// System.out.println("显示signName:"+signName);
String templateCode = messageProperties.getMsn().getTemplateCode();
String templateParam = messageProperties.getMsn().getTemplateParam();
Map map = new HashMap<>();
//随机生成六位验证码
String verifyCode = String.valueOf((Math.random()*9+1)*100000).substring(0,length);
map.put(templateParam,verifyCode);
String code = JSON.toJSONString(map);
DefaultProfile profile = DefaultProfile.getProfile(regionId,accessKeyId,accessSecret);
IAcsClient client = new DefaultAcsClient(profile);
CommonRequest request = new CommonRequest();
request.setMethod(MethodType.POST);
request.setDomain("dysmsapi.aliyuncs.com");
request.setVersion("2017-05-25");
request.setAction("SendSms");
request.putQueryParameter("RegionId", regionId);
request.putQueryParameter("PhoneNumbers", phone);
request.putQueryParameter("SignName", );
request.putQueryParameter("TemplateCode", templateCode);
request.putQueryParameter("TemplateParam",code);
try {
CommonResponse response = client.getCommonResponse(request);
} catch (ServerException e) {
e.printStackTrace();
} catch (ClientException e) {
e.printStackTrace();
}
return verifyCode;
}
/**
* 邮件
* @return
*/
@GetMapping("/mail")
public String sample() {
//邮件发送结果
String result = "";
// 如果是除杭州region外的其它region（如新加坡、澳洲Region），需要将下面的"cn-hangzhou"替换为"ap-southeast-1"、或"ap-southeast-2"。
IClientProfile profile = DefaultProfile.getProfile(messageProperties.getMail().getRegionId(), messageProperties.getMail().getAccessKeyId(), messageProperties.getMail().getAccessKeySecret());
// 如果是除杭州region外的其它region（如新加坡region）， 需要做如下处理
//try {
//DefaultProfile.addEndpoint("dm.ap-southeast-1.aliyuncs.com", "ap-southeast-1", "Dm", "dm.ap-southeast-1.aliyuncs.com");
//} catch (ClientException e) {
//e.printStackTrace();
//}
IAcsClient client = new DefaultAcsClient(profile);
SingleSendMailRequest request = new SingleSendMailRequest();
try {
//request.setVersion("2017-06-22");// 如果是除杭州region外的其它region（如新加坡region）,必须指定为2017-06-22
request.setAccountName(messageProperties.getMail().getAccountName());
request.setFromAlias();
request.setAddressType(messageProperties.getMail().getAddressType());
request.setTagName(messageProperties.getMail().getTagName());
request.setReplyToAddress(true);
request.setToAddress(messageProperties.getMail().getToAddress());
//可以给多个收件人发送邮件，收件人之间用逗号分开，批量发信建议使用BatchSendMailRequest方式
//request.setToAddress("邮箱1,邮箱2");
request.setSubject("尊敬的用户您好:");
//随机生成六位验证码
String verifyCode = String.valueOf((Math.random()*9+1)*100000).substring(0,6);
request.setHtmlBody("此邮件为开发邮件功能的测试邮件，验证码为："+verifyCode);
//开启需要备案，0关闭，1开启
//request.setClickTrace("0");
//如果调用成功，正常返回httpResponse；如果调用失败则抛出异常，需要在异常中捕获错误异常码；错误异常码请参考对应的API文档;
SingleSendMailResponse httpResponse = client.getAcsResponse(request);
result = httpResponse.getEnvId() + " "+httpResponse.getRequestId();
} catch (ServerException e) {
//捕获错误异常码
System.out.println("ErrCode : " + e.getErrCode());
e.printStackTrace();
}
catch (ClientException e) {
//捕获错误异常码
System.out.println("ErrCode : " + e.getErrCode());
e.printStackTrace();
}
return result;
}
}
(5)、使用
①如果是在信息发送服务模块使用，需要在启动类上加 @EnableConfigurationProperties(MessageProperties.class) 来让读取属性配置生效；
②如果是在别的模块使用短信服务发送功能，也需要在使用的模块的启动类上加 @EnableConfigurationProperties(MessageProperties.class) 来让读取属性配置生效；同时还要在配置类中新建一个@Bean
/**
* 消息服务的Bean
* @return
*/
@Bean
public MessageService messageService(){
return new MessageService();
}（6)、关于springsecurity拦截静态资源的问题
同样需要在继承了 WebSecurityConfigurerAdapter 的子类中，加入配置来屏蔽springsecurity对静态资源的拦截。
@Override
public void configure(WebSecurity web) throws Exception {
//解决静态资源被SpringSecurity拦截的问题
// "/static/**"的意思是任何以 static地址开头的资源都能被访问
web.ignoring().antMatchers("/static/**","/jquery/**","/layui/**");
}2、校验短信验证码并登录
可参考的文章：SpringBoot 集成 Spring Security（8）——短信验证码登录
8.2.1 新建一个token的类(MsnCodeAuthenticationToken)
package security.core.authentication.mobile;
import org.springframework.security.authentication.AbstractAuthenticationToken;
import org.springframework.security.core.GrantedAuthority;
import java.util.Collection;
/**
* 短信登录 AuthenticationToken，模仿 UsernamePasswordAuthenticationToken 实现
* 封装认证信息
*/
public class MsnCodeAuthenticationToken extends AbstractAuthenticationToken {
private static final long serialVersionUID = 8499397320892255781L;
/**
* principal:用于存放认证信息，登陆前放手机号，登录成功后放入登录的用户信息
* 在 UsernamePasswordAuthenticationToken 中该字段代表登录的用户名，
* 在这里就代表登录的手机号码
*/
private final Object principal;
/**
* 构建一个没有鉴权的 MsnAuthenticationToken,这时候principal中存放的是用户的手机号
*/
public MsnCodeAuthenticationToken(Object mobile) {
super(null);
this.principal = mobile;
//没登陆的时候设为false，即认证不通过
setAuthenticated(false);
}
/**
* 构建拥有鉴权的 MsnAuthenticationToken,这时候principal中存放的是用户信息
*/
public MsnCodeAuthenticationToken(Object user, Collection authorities) {
super(authorities);
this.principal = user;
//验证登陆成功后设为true，即认证通过
super.setAuthenticated(true);
}
@Override
public Object getCredentials() {
return null;
}
@Override
public Object getPrincipal() {
return this.principal;
}
@Override
public void setAuthenticated(boolean isAuthenticated) throws IllegalArgumentException {
if (isAuthenticated) {
throw new IllegalArgumentException(
"Cannot set this token to trusted - use constructor which takes a GrantedAuthority list instead");
}
super.setAuthenticated(false);
}
@Override
public void eraseCredentials() {
super.eraseCredentials();
}
}8.2.2 新建一个校验短信验证码的过滤器（MsnCodeAuthenticationFilter)
package security.core.authentication.mobile;
import org.springframework.security.authentication.AuthenticationServiceException;
import org.springframework.security.core.Authentication;
import org.springframework.security.core.AuthenticationException;
import org.springframework.security.web.authentication.AbstractAuthenticationProcessingFilter;
import org.springframework.security.web.util.matcher.AntPathRequestMatcher;
import org.springframework.util.Assert;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
/**
* 短信登录的鉴权过滤器，模仿 UsernamePasswordAuthenticationFilter 实现
*/
public class MsnCodeAuthenticationFilter extends AbstractAuthenticationProcessingFilter {
/**
* form表单中手机号码的字段name

@Component
@Slf4j
public class MsnCodeAuthenticationSuccessHandler implements AuthenticationSuccessHandler {
@Autowired
private ObjectMapper objectMapper;
@Override
public void onAuthenticationSuccess(HttpServletRequest request, HttpServletResponse response, Authentication authentication) throws IOException, ServletException {
log.info("登录成功");

8.2.6 新建一个短信验证码的配置类 ( MsnCodeAuthenticationSecurityConfig )，将前面的配置组装起来
package security.core.authentication.mobile;

/**
* 短信验证码的配置类
*/
@Component
public class MsnCodeAuthenticationSecurityConfig extends SecurityConfigurerAdapter {
@Autowired
private UserDetailsService userDetailsService;
@Autowired
private MsnCodeAuthenticationSuccessHandler msnCodeAuthenticationSuccessHandler;
@Autowired
private MsnCodeAuthenticationFailureHandler msnCodeAuthenticationFailureHandler;
@Override
public void configure(HttpSecurity http) throws Exception {
//1、过滤器配置 AuthenticationManager、MsnCodeAuthenticationSuccessHandler、MsnCodeAuthenticationFailureHandler
MsnCodeAuthenticationFilter msnCodeAuthenticationFilter = new MsnCodeAuthenticationFilter();
msnCodeAuthenticationFilter.setAuthenticationManager(http.getSharedObject(AuthenticationManager.class));
msnCodeAuthenticationFilter.setAuthenticationSuccessHandler(msnCodeAuthenticationSuccessHandler);
msnCodeAuthenticationFilter.setAuthenticationFailureHandler(msnCodeAuthenticationFailureHandler);
//2、Provider 配置 UserDetailsService
MsnCodeAuthenticationProvider smsCodeAuthenticationProvider = new MsnCodeAuthenticationProvider();
smsCodeAuthenticationProvider.setUserDetailsService(userDetailsService);
//3、将 过滤器、Provider配置到springsecurity的authentication认证链上
http.authenticationProvider(smsCodeAuthenticationProvider)
.addFilterAfter(msnCodeAuthenticationFilter, UsernamePasswordAuthenticationFilter.class);
}
}
8.2.7 在 继承了 WebSecurityConfigurerAdapter的配置类 BrowserSecurityConfig 将短信验证码的认证加入到spring security的认证链上
(1)加入 MessageService、MsnCodeAuthenticationSecurityConfig、MsnCodeAuthenticationSuccessHandler、MsnCodeAuthenticationFailureHandler的配置
/**
* 消息服务的Bean
* @return
*/
@Bean
public MessageService messageService(){
return new MessageService();
}
@Bean
public MsnCodeAuthenticationSecurityConfig getMsnCodeAuthenticationSecurityConfig(){

@Bean
public MsnCodeAuthenticationSuccessHandler getMsnCodeAuthenticationSuccessHandler(){
return new MsnCodeAuthenticationSuccessHandler();
}
@Bean
public MsnCodeAuthenticationFailureHandler getMsnCodeAuthenticationFailureHandler(){
return new MsnCodeAuthenticationFailureHandler();
}(2) 加入到Filter链上
http.apply(msnCodeAuthenticationSecurityConfig).and()
.addFilterBefore(validateCodeFilter, UsernamePasswordAuthenticationFilter.class)(3)放过对验证码登录请求的拦截
.antMatchers("/authentication/require","/authentication/mobile",
securityProperties.getBrowser().getLoginPage(),
"/code/*").permitAll()//允许signIn.html请求进来,不进行拦截完整代码：
