一、Spring Security安全框架
1.1 权限管理概述
BRAC的模型：基于角色的访问控制模型。
1.2 Security框架基本介绍
Spring Security 的前身是 Acegi Security ，是 Spring 项目组中用来提供安全认证服务的框架。(https://projects.spring.io/spring-security/)
Spring Security 为基于J2EE企业应用软件提供了全面安全服务。特别是使用领先的J2EE解决方案-Spring框架开发的企业软件项目。人们使用Spring Security有很多种原因，不过通常吸引他们的是在J2EE Servlet规范或EJB规范中找不到典型企业应用场景的解决方案。
特别要指出的是他们不能再WAR 或 EAR 级别进行移植。这样，如果你更换服务器环境，就要，在新的目标环境进行大量的工作，对你的应用系统进行重新配 置安全。使用Spring Security 解决了这些问题，也为你提供很多有用的，完全可以指定的其他安全特性。
安全包括两个主要操作。
- “认证”，是为用户建立一个他所声明的主体。主题一般是指用户，设备或可以在你系统中执行动作的其他系统。
- “授权”指的是一个用户能否在你的应用中执行某个操作，在到达授权判断之前，身份的主题已经由 身份验证过程建立了。
这些概念是通用的，不是Spring Security特有的。在身份验证层面，Spring Security广泛支持各种身份验证模式，这些验证模型绝大多数都由第三方提供，或则正在开发的有关标准机构提供的，例如 Internet Engineering Task Force.作为补充，Spring Security 也提供了自己的一套验证功能。
Spring Security 目前支持认证一体化如下认证技术：
HTTP BASIC authentication headers (一个基于IEFT RFC 的标准)
HTTP Digest authentication headers (一个基于IEFT RFC 的标准)
HTTP X.509 client certificate exchange (一个基于IEFT RFC 的标准)
LDAP (一个非常常见的跨平台认证需要做法，特别是在大环境)
Form-based authentication (提供简单用户接口的需求)
OpenID authentication
Computer Associates Siteminder
JA-SIG Central Authentication Service (CAS，这是一个流行的开源单点登录系统)
Transparent authentication context propagation for Remote Method Invocation and HttpInvoker (一个Spring远程调用协议)

1.3 SpringSecurity入门案例
1.3.1 创建一个war包工程
创建一个普通的war包工程，名字可以叫springsecurity-demo，引入相关依赖
pom.xml
<project xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

1.3.2 配置web.xml
其中监听器主要用于加载配置文件，过滤器用于配置用户拦截，过滤器名字必须为 springSecurityFilterChain
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"
version="3.1">
<context-param>
<param-name>contextConfigLocationparam-name>
<param-value>classpath:spring-security.xmlparam-value>
context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListenerlistener-class>

filter>
<filter-mapping>
<filter-name>springSecurityFilterChainfilter-name>
<url-pattern>/*url-pattern>
filter-mapping>
web-app>
1.3.3 配置spring-security.xml
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:security="http://www.springframework.org/schema/security"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/security
http://www.springframework.org/schema/security/spring-security.xsd">
<security:http auto-config="true" use-expressions="false">
<security:intercept-url pattern="/**" access="ROLE_USER" />
security:http>
<security:authentication-manager>
<security:authentication-provider>
<security:user-service>
<security:user name="admin" password="{noop}admin" authorities="ROLE_USER" />
security:user-service>
security:authentication-provider>
security:authentication-manager>
beans>
1.3.4 测试
当访问index.jsp页面时发现会弹出登录窗口，可能你会奇怪，我们没有建立下面的登录页面，为什么Spring Security会跳到上面的登录页面呢？这是我们设置http的auto-config=”true”时Spring Security自动为我们生成的。
1.3.5 使用自定义页面
我们分别创建一个登录成功页面和登录失败页面以及登录页面，并且实现自定义登录成功、失败、登录等跳转。
1.3.5.1 登录页面 login.html
<html>
<head>
<meta charset="UTF-8">
<title>Insert title heretitle>
head>
<body>
<form action="login" method="post">
<table>
<tr>
<td>用户名：td>
<td><input type="text" name="username" />td>
tr>
<tr>
<td>密码：td>
<td><input type="password" name="password" />td>
tr>
<tr>
<td colspan="2" align="center"><input type="submit" value="登录" />
<input type="reset" value="重置" />td>
tr>
table>
form>
body>
html>
1.3.5.2 登录成功页面 success.html
<html>
<head>
<meta charset="UTF-8">
<title>Insert title heretitle>
head>
<body>
success html<br>
<a href="logout">退出a>
body>
html>
1.3.5.3 登录失败页面 failer.html
<html>
<head>
<meta charset="UTF-8">
<title>Insert title heretitle>
head>
<body>
登录失败
body>
html>
1.3.5.4 自定义页面跳转[配置spring-security.xml
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:security="http://www.springframework.org/schema/security"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd

http://www.springframework.org/schema/security/spring-security.xsd">
<security:http pattern="/login.html" security="none" />
<security:http pattern="/failer.html" security="none" />
<security:http auto-config="true" use-expressions="false">
<security:intercept-url pattern="/**" access="ROLE_USER" />
<security:form-login
login-page="/login.html"
login-processing-url="/login"
default-target-url="/success.html"
authentication-failure-url="/failer.html"
/>
<security:csrf disabled="true" />
<security:logout
logout-success-url="/login.html"
invalidate-session="true"
logout-url="/logout"
/>

<security:authentication-provider>
<security:user-service>
<security:user name="admin" password="{noop}admin" authorities="ROLE_USER" />
security:user-service>
security:authentication-provider>
security:authentication-manager>
beans>
二、搭建用户的开发环境
先上个人工程项目结构
2.1 创建表结构
mysql
--创建用户表
CREATE TABLE `sys_user` (
`id` int(10) NOT NULL AUTO_INCREMENT,
`username` varchar(50) DEFAULT NULL,
`email` varchar(50) DEFAULT NULL,
`PASSWORD` varchar(80) DEFAULT NULL,
`phoneNum` varchar(20) DEFAULT NULL,
`STATUS` int(1) DEFAULT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
2.2 创建SysUser
在ssm-model中创建SysUser
public class SysUser {
private Long id;
private String username;
private String email;
private String password;
private String phoneNum;
private int status;
//get...set...
}
2.3 自定义认证程序
2.3.1 导入依赖包
在ssm-parent中引入依赖管理
<properties>
<spring.security.version>5.0.1.RELEASEspring.security.version>
properties>
//依赖管理
<dependencies>
<dependency>
<groupId>org.springframework.securitygroupId>
<artifactId>spring-security-webartifactId>
<version>${spring.security.version}version>
dependency>
<dependency>
<groupId>org.springframework.securitygroupId>
<artifactId>spring-security-configartifactId>
<version>${spring.security.version}version>
dependency>
dependencies>
在ssm-service中引入依赖
<dependency>
<groupId>org.springframework.securitygroupId>
<artifactId>spring-security-webartifactId>
dependency>
<dependency>
<groupId>org.springframework.securitygroupId>
<artifactId>spring-security-configartifactId>
dependency>
2.3.2 自定义认证类
在ssm-service中创建UserService接口，让该接口继承UserDetailsService
public interface UserService extends UserDetailsService {
}
创建UserServiceImpl实现UserService，同时实现loadUserByUsername方法，在该方法中写登录认证程序
@Service
public class UserServiceImpl implements UserService {
@Override
public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
// 先设置假的权限
List<GrantedAuthority> authorities = new ArrayList<>();
// 传入角色
authorities.add(new SimpleGrantedAuthority("ROLE_USER"));
// 创建用户
User user = new User(username, "{noop}admin", authorities) ;
return user;
}
}
2.3.3 继承SpringSecurity
2.3.3.1 过滤器配置
在ssm-web中修改web.xml，加入springsecurity过滤器
<filter>
<filter-name>springSecurityFilterChainfilter-name>
<filter-class>org.springframework.web.filter.DelegatingFilterProxyfilter-class>
filter>
<filter-mapping>
<filter-name>springSecurityFilterChainfilter-name>
<url-pattern>/*url-pattern>
filter-mapping>
2.3.3.2 配置springsecurity.xml
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:security="http://www.springframework.org/schema/security"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/security
http://www.springframework.org/schema/security/spring-security.xsd">
<security:http pattern="/*.jsp" security="none" />
<security:http pattern="/css/**" security="none" />
<security:http pattern="/img/**" security="none" />
<security:http pattern="/plugins/**" security="none" />
<security:http auto-config="true" use-expressions="false">
<security:intercept-url pattern="/index.jsp" access="ROLE_USER" />
<security:intercept-url pattern="/**" access="ROLE_USER" />
<security:form-login
login-page="/login.jsp"
login-processing-url="/login"
default-target-url="/pages/main.jsp"
authentication-failure-url="/failer.jsp"
/>
<security:csrf disabled="true" />
<security:logout
logout-success-url="/login.jsp"
invalidate-session="true"
logout-url="/logout"
/>
security:http>
<security:authentication-manager>
<security:authentication-provider user-service-ref="userServiceImpl">
security:authentication-provider>
security:authentication-manager>
beans>
4.3.3.3 引入springsecurity配置
修改springmvc.xml，添加导入springsecurity.xml
<import resource="spring-security.xml" />
4.3.3.4 修改登录地址
修改login.jsp，将action地址改成/login
<form action="${pageContext.request.contextPath}/login" method="post">
//...略
form>
4.3.3.5 修改index.jsp
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>主页title>
head>
<body>
<script>
location.href="/pages/main.jsp";
script>
body>
html>
至此，可以实现登录校验了。
2.4 数据库校验
可以将上述功能写死的账号密码从数据库获取，只需要修改UserServiceImpl，调用Dao从数据库查询即可。
2.4.1 Dao实现数据库查询
创建UserDao
public interface UserDao {
/***
* 查询用户信息
* @param name
* @return
*/
@Select("select * from sys_user where username=#{username}")
SysUser getByUserName(String name);
}
2.4.2 调用Dao实现数据库查询账号信息
@Service
public class UserServiceImpl implements UserService {
@Autowired
private UserDao userDao;
@Override
public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
// 先设置假的权限
List<GrantedAuthority> authorities = new ArrayList<>();
// 传入角色
authorities.add(new SimpleGrantedAuthority("ROLE_USER"));
//通过账号查询用户信息
SysUser sysUser = userDao.getByUserName(username);
// 创建用户，此方法将会对用户名和密码进行校验，并赋予权限，User对象是springsecurity内部的User对象
User user = new User(username, "{noop}"+sysUser.getPassword(), authorities) ;
return user;
}
}
