一、前言

CAS Client端可分为简单的Servlet配置方式和Spring MVC，Shiro整合配置方式，将分两次说明，这里先讲简单的Servlet配置方式

二、环境

Tomcat7

JDK7

CAS Client版本：3.4.1

IDE：IDEA 14.1.7

测试源代码下载：http://git.oschina.net/tsfdez/cas-test

三、建立项目

通过Maven建立名为cas-test的项目，在里面建立三个web模组，分别是test1，test2，test3，其中test1，test2都是Servlet配置方式，test3是Spring MVC，Shiro整合配置方式，这个下一讲在说明

四、项目配置

先配置test1模组

将之前生成的证书复制过去

打开pom.xml文件，增加cas-client-core依赖配置及Tomcat配置

1.  `<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"`
2.  `xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">`

打开WEB-INF/web.xml，增加CAS配置

1.  `<?xml version="1.0" encoding="UTF-8"?>`
2.  `<web-app xmlns="http://java.sun.com/xml/ns/javaee"`
3.  `xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"`

67. ``
68. `</web-app>`

启动Tomcat，在浏览器输入https://localhost:9002/test1，试试账号登录与退出，退出输入https://localhost:9001/cas/logout

![20170725115352663][]

这边说下单点登出，登出实际上访问Server端的logout地址，Server端会通知其他Client端登出，若是不想同步的，可以注释掉web.xml的这一段

1.  ``
2.  `<listener>`
3.  `<listener-class>org.jasig.cas.client.session.SingleSignOutHttpSessionListener</listener-class>`
4.  `</listener>`
5.   
6.  ``
7.  `<filter>`
8.  `<filter-name>CAS Single Sign Out Filter</filter-name>`
9.  `<filter-class>org.jasig.cas.client.session.SingleSignOutFilter</filter-class>`
10. `<init-param>`
11. `<param-name>casServerUrlPrefix</param-name>`
12. `<param-value>https://localhost:9001/cas</param-value>`
13. `</init-param>`
14. `</filter>`
15. `<filter-mapping>`
16. `<filter-name>CAS Single Sign Out Filter</filter-name>`
17. `<url-pattern>/*</url-pattern>`
18. `</filter-mapping>`

在webapp下增加一个登出页面logout.jsp，通过访问这个页面实现登出

1.  `<%@ page contentType="text/html;charset=UTF-8" language="java" %>`
2.  `<html>`
3.  `<head>`
4.  `<title></title>`
5.  `</head>`
6.  `<body>`
7.  `<%`
8.  `session.invalidate();`
9.  `response.sendRedirect("https://localhost:9001/cas/logout?service=https://localhost:9002/test1");`
10. `%>`
11. `</body>`
12. `</html>`

test2的配置就不细说了，跟test1一样，修改一下端口就行

test2配置好了，可以测试一下两个节点登录登出是否同步
