spring security完全可以作为一个专门的专题来说,有一个专题写的不错http://www.iteye.com/blogs/subjects/spring_security,我这里主要是针对4.1.3进行配置说明
//spring-security
compile 'org.springframework.security:spring-security-web:4.1.3.RELEASE'
compile 'org.springframework.security:spring-security-config:4.1.3.RELEASE'
compile 'org.springframework.security:spring-security-taglibs:4.1.3.RELEASE'
从4以后security就只吃java配置了,具体可以看下《spring in action第四版》,我这里还是使用xml配置
过滤器配置,security是基于过滤器的,web.xml
springSecurityFilterChain
org.springframework.web.filter.DelegatingFilterProxy
springSecurityFilterChain
/*
需要注意的是,如果配置了sitemesh装饰器,如果在装饰器页面中用到了security,比如标签,那么security过滤器需要配置在sitemesh之前,否则装饰器页中的
springSecurityFilterChain
org.springframework.web.filter.DelegatingFilterProxy
springSecurityFilterChain
/*
sitemesh
org.sitemesh.config.ConfigurableSiteMeshFilter
ignore
true
encoding
UTF-8
sitemesh
/*
装饰器页面中的使用
你好,欢迎来到Mango!登录
欢迎光临Mango!退出
applicationContext-security.xml
这里配置了自定义登录界面/login,还需要配置控制器条撞到login.jsp页面,如果字段使用默认值为username和password,当然也可以用 form-login标签中的属性username-parameter="username"password-parameter="password" 进行设置,这里的值要和登录页面中的字段一致。login.jsp
<%@ page language="java" pageEncoding="UTF-8" contentType="text/html;charset=UTF-8"%>
<%@ include file="../includes/taglibs.jsp"%>
Mango-Login
请登录!
其中,form action的值要和配置文件中login-process-url的值一致,提交后UsernamePasswordAuthenticationFilter才能对其进行授权认证。
另外认证是采用的自定义myUserDetailsService获取用户信息方式,由于该项目中集成的是Hibernate,所以自己定义了,security系统中是支持jdbc进行获取的
package com.mango.jtt.springSecurity;
import org.springframework.beans.factory.annotation.Autowired;
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.Service;
import com.mango.jtt.po.MangoUser;
import com.mango.jtt.service.IUserService;
/**
* 从数据库中获取信息的自定义类
*
* @author HHL
*
*/
@Service
public class MyUserDetailsService implements UserDetailsService {
@Autowired
private IUserService userService;
/**
* 获取用户信息,设置角色
*/
@Override
public UserDetails loadUserByUsername(String username)
throws UsernameNotFoundException {
// 获取用户信息
MangoUser mangoUser = userService.getUserByName(username);
if (mangoUser != null) {
// 设置角色
return new User(mangoUser.getUserName(), mangoUser.getPassword(),
AuthorityUtils.createAuthorityList(mangoUser.getRole()));
}
throw new UsernameNotFoundException("User '" + username
+ "' not found.");
}
}
认证成功之后也是自定义了处理类myAuthenticationSuccessHandler,该处理类继承了SavedRequestAwareAuthenticationSuccessHandler,实现了保存请求信息的操作,如果不配置,默认的也是交给SavedRequestAwareAuthenticationSuccessHandler处理,因为在解析security配置文件时,如果没有配置会将此设置为默认值。
package com.mango.jtt.springSecurity;
import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.security.core.Authentication;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.security.web.authentication.SavedRequestAwareAuthenticationSuccessHandler;
import org.springframework.stereotype.Component;
import com.mango.jtt.po.MangoUser;
import com.mango.jtt.service.IUserService;
/**
* 登录后操作
*
* @author HHL
* @date
*
*/
@Component
public class MyAuthenticationSuccessHandler extends
SavedRequestAwareAuthenticationSuccessHandler {
@Autowired
private IUserService userService;
@Override
public void onAuthenticationSuccess(HttpServletRequest request,
HttpServletResponse response, Authentication authentication)
throws IOException, ServletException {
// 认证成功后,获取用户信息并添加到session中
UserDetails userDetails = (UserDetails) authentication.getPrincipal();
MangoUser user = userService.getUserByName(userDetails.getUsername());
request.getSession().setAttribute("user", user);
super.onAuthenticationSuccess(request, response, authentication);
}
}
认证失败则回到登录页,只不过多了error,配置为authentication-failure-url="/login?error" 控制类会对其进行处理
/**
*
*/
package com.mango.jtt.controller;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
/**
* @author HHL
*
* @date 2016年12月8日
*
* 用户控制类
*/
@Controller
public class UserController {
/**
* 显示登录页面用,主要是显示错误信息
*
* @param model
* @param error
* @return
*/
@RequestMapping("/login")
public String login(Model model,
@RequestParam(value = "error", required = false) String error) {
if (error != null) {
model.addAttribute("error", "用户名或密码错误");
}
return "login";
}
}
另外,从spring security3.2开始,默认就会启用csrf保护,本次将csrf保护功能禁用
