CAS客户端与SpringSecurity集成
4. CAS客户端与SpringSecurity集成
4.1 Spring Security测试工程搭建
（1）建立Maven项目casclient_demo3 ，引入spring依赖和spring secrity 相关依赖 ，tomcat端口设置为9003
（2）建立web.xml ,添加过滤器等配置
（3）创建配置文件spring-security.xml
（4）添加html页面
4.2 Spring Security与 CAS集成
（1）引入依赖
|
<dependency> <groupId>org.springframework.security</groupId> <artifactId>spring-security-cas</artifactId> <version>4.1.0.RELEASE</version> </dependency> <dependency> <groupId>org.jasig.cas.client</groupId> <artifactId>cas-client-core</artifactId> <version>3.3.3</version> <exclusions> <exclusion> <groupId>org.slf4j</groupId> <artifactId>log4j-over-slf4j</artifactId> </exclusion> </exclusions> </dependency> |
（2）修改spring-security.xml
|
<?xml version="1.0" encoding="UTF-8"?> <beans:beans xmlns="http://www.springframework.org/schema/security" xmlns:beans="http://www.springframework.org/schema/beans" 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">
<!-- entry-point-ref 入口点引用 --> <http use-expressions="false" entry-point-ref="casProcessingFilterEntryPoint"> <intercept-url pattern="/**" access="ROLE_USER"/> <csrf disabled="true"/> <!-- custom-filter为过滤器， position 表示将过滤器放在指定的位置上，before表示放在指定位置之前 ，after表示放在指定的位置之后 --> <custom-filter ref="casAuthenticationFilter" position="CAS_FILTER" /> <custom-filter ref="requestSingleLogoutFilter" before="LOGOUT_FILTER"/> <custom-filter ref="singleLogoutFilter" before="CAS_FILTER"/> </http>
<!-- CAS入口点 开始 --> <beans:bean id="casProcessingFilterEntryPoint" class="org.springframework.security.cas.web.CasAuthenticationEntryPoint"> <!-- 单点登录服务器登录URL --> <beans:property name="loginUrl" value="http://localhost:9100/cas/login"/> <beans:property name="serviceProperties" ref="serviceProperties"/> </beans:bean> <beans:bean id="serviceProperties" class="org.springframework.security.cas.ServiceProperties"> <!--service 配置自身工程的根地址+/login/cas --> <beans:property name="service" value="http://localhost:9003/login/cas"/> </beans:bean> <!-- CAS入口点 结束 -->
<!-- 认证过滤器 开始 --> <beans:bean id="casAuthenticationFilter" class="org.springframework.security.cas.web.CasAuthenticationFilter"> <beans:property name="authenticationManager" ref="authenticationManager"/> </beans:bean> <!-- 认证管理器 --> <authentication-manager alias="authenticationManager"> <authentication-provider ref="casAuthenticationProvider"> </authentication-provider> </authentication-manager> <!-- 认证提供者 --> <beans:bean id="casAuthenticationProvider" class="org.springframework.security.cas.authentication.CasAuthenticationProvider"> <beans:property name="authenticationUserDetailsService"> <beans:bean class="org.springframework.security.core.userdetails.UserDetailsByNameServiceWrapper"> <beans:constructor-arg ref="userDetailsService" /> </beans:bean> </beans:property> <beans:property name="serviceProperties" ref="serviceProperties"/> <!-- ticketValidator 为票据验证器 --> <beans:property name="ticketValidator"> <beans:bean class="org.jasig.cas.client.validation.Cas20ServiceTicketValidator"> <beans:constructor-arg index="0" value="http://localhost:9100/cas"/> </beans:bean> </beans:property> <beans:property name="key" value="an_id_for_this_auth_provider_only"/> </beans:bean> <!-- 认证类 --> <beans:bean id="userDetailsService" class="cn.itcast.demo.service.UserDetailServiceImpl"/>
<!-- 认证过滤器 结束 --> <!-- 单点登出 开始 --> <beans:bean id="singleLogoutFilter" class="org.jasig.cas.client.session.SingleSignOutFilter"/> <beans:bean id="requestSingleLogoutFilter" class="org.springframework.security.web.authentication.logout.LogoutFilter"> <beans:constructor-arg value="http://localhost:9100/cas/logout?service=http://www.baidu.com"/> <beans:constructor-arg> <beans:bean class="org.springframework.security.web.authentication.logout.SecurityContextLogoutHandler"/> </beans:constructor-arg> <beans:property name="filterProcessesUrl" value="/logout/cas"/> </beans:bean> <!-- 单点登出 结束 --> </beans:beans> |
（3）创建UserDetailsServiceImpl
|
/** * 认证类 */ public class UserDetailServiceImpl implements UserDetailsService { @Override public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException { //构建角色集合 List<GrantedAuthority> authorities=new ArrayList(); authorities.add(new SimpleGrantedAuthority("ROLE_USER")); return new User(username, "" , authorities); } } |
这个类的主要作用是在登陆后得到用户名，可以根据用户名查询角色或执行一些逻辑。
4.3获取登录名
我们在处理后端逻辑需要获得登录名，那么如何获取单点登录的用户名呢? 其实和我们之前获得用户名的方式是完全相同的，我们下面来做个测试。
（1）web.xml 添加springmvc
|
<servlet> <servlet-name>springmvc</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <!-- 指定加载的配置文件 ，通过参数contextConfigLocation加载--> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:springmvc.xml</param-value> </init-param> </servlet>
<servlet-mapping> <servlet-name>springmvc</servlet-name> <url-pattern>*.do</url-pattern> </servlet-mapping> |
（2）创建springmvc.xml
|
<context:component-scan base-package="cn.itcast.demo" /> <mvc:annotation-driven /> |
（3）创建UserController
|
@RestController public class UserController { @RequestMapping("/findLoginUser") public void findLoginUser(){ String name = SecurityContextHolder.getContext().getAuthentication().getName(); System.out.println(name); } } |
地址栏输入http://localhost:9003/findLoginUser.do 即可在控制台看到输出的登录名。
4.4退出登录
修改spring-security.xml
|
<beans:bean id="requestSingleLogoutFilter" class="org.springframework.security.web.authentication.logout.LogoutFilter"> <beans:constructor-arg value="http://localhost:9100/cas/logout?service=http://localhost:9003/index2.html"/> <beans:constructor-arg> <beans:bean class="org.springframework.security.web.authentication.logout.SecurityContextLogoutHandler"/> </beans:constructor-arg> <beans:property name="filterProcessesUrl" value="/logout/cas"/> </beans:bean> |
在页面上添加链接
|
<a href="/logout/cas">退出登录</a> |
创建index2.html,将index2.html设置为可匿名访问
|
<http pattern="/index2.html" security="none"></http> |
5.品优购用户中心
5.1需求分析
用户中心实现单点登录。
5.2代码实现
5.2.1用户中心实现单点登录
（1）将用户中心相关的页面（home-开头的）拷贝至 pinnyougou-user-web
（2）pom.xml 引入springSecurity、cas客户端和springSecurity Cas整合包依赖（参照casclient_demo3）。
（3）web.xml 添加spring-security过滤器（参照参照casclient_demo3）设置首页为home-index.html
|
<welcome-file-list> <welcome-file>home-index.html</welcome-file> </welcome-file-list> |
（4）构建UserDetailsServiceImpl.java （参照casclient_demo3）
（5）添加spring-security.xml（参照casclient_demo3），并做以下修改
配置匿名访问资源
|
<!-- 匿名访问资源 --> <http pattern="/css/**" security="none"></http> <http pattern="/js/**" security="none"></http> <http pattern="/image/**" security="none"></http> <http pattern="/plugins/**" security="none"></http> <http pattern="/register.html" security="none"></http> <http pattern="/user/add.do" security="none"></http> <http pattern="/user/sendCode.do" security="none"></http> |
设置服务地址属性
|
<beans:bean id="serviceProperties" class="org.springframework.security.cas.ServiceProperties"> <beans:property name="service" value="http://localhost:9106/login/cas"/> </beans:bean> |
设置认证类
|
<beans:bean id="userDetailsService" class="com.pinyougou.user.service.UserDetailServiceImpl"/> |
5.2.2页面显示用户名
（1）pinyougou-user-web创建LoginController.java
|
@RestController @RequestMapping("/login") public class LoginController { @RequestMapping("/name") public Map showName(){ String name = SecurityContextHolder.getContext().getAuthentication().getName();//得到登陆人账号 Map map=new HashMap<>(); map.put("loginName", name); return map; } } |
（2）创建loginService.js
|
//服务层 app.service('loginService',function($http){ //读取列表数据绑定到表单中 this.showName=function(){ return $http.get('../login/name.do'); } }); |
（3）创建indexController.js
|
//首页控制器 app.controller('indexController',function($scope,loginService){ $scope.showName=function(){ loginService.showName().success( function(response){ $scope.loginName=response.loginName; } ); } }); |
（5）修改home-index.html 引入js
|
<script type="text/javascript" src="plugins/angularjs/angular.min.js"></script> <script type="text/javascript" src="js/base.js"></script> <script type="text/javascript" src="js/service/loginService.js"></script> <script type="text/javascript" src="js/controller/indexController.js"></script> |
指令，调用方法查询登陆名
|
<body ng-app="pinyougou" ng-controller="indexController" ng-init="showName()"> |
显示用户名
|
<span class="name">{{loginName}}</span> |
5.2.3退出登录
设置退出登录后的跳转地址
|
<beans:bean id="requestSingleLogoutFilter" class="org.springframework.security.web.authentication.logout.LogoutFilter"> <beans:constructor-arg value="http://localhost:9100/cas/logout?service=http://localhost:9103"/> ........ </beans:bean> |
退出登录后，跳转到网站首页
|
<span class="safe"> <a href="/logout/cas">退出登录 </a></span> |
