CAS客户端入门小Demo

搭建工程1搭建

(1)搭建工程引入依赖
创建Maven工程 (war)songzixian_demo1 引入cas客户端依赖并制定tomcat运行端口为9001

引入依赖

添加web.xml

(2)添加web.xml

编写index.jsp

编写index.jsp

<%@ page language="java" contentType="text/html; charset=utf-8"
    pageEncoding="utf-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>宋子宪博客-CAS客户端入门小Demo</title>
</head>
<body>
欢迎来到宋子宪博客
<%=request.getRemoteUser()%>
</body>
</html>

说明request.getRemoteUser()为获取远程登录名

客户端工程2搭建

客户端工程2搭建
(1)创建Maven工程 (war)casclient_demo2 引入cas客户端依赖并制定tomcat运行端口为9002
(2)创建web.xml,参照casclient_demo1 ,将serverName的值改为http://localhost:9002,一共两处
(3)创建index.jsp ,内容显示“欢迎来到宋子宪笔记网

单点登录测试

单点登录测试
(1)启动cas部署的tomcat
(2)启动客户端工程1和客户端工程2
(3)地址栏输入http://localhost:9001/http://localhost:9002/ ,地址均会跳转到CAS登录页
(4)输入用户名和密码后,页面跳转回9002 ,再次访问9001也可以打开主页面。

单点退出登录

地址栏输入 http://localhost:9100/cas/logout
即可看到退出后的提示页面

我们可以将这个链接添加到index.jsp中

<a href="http://localhost:9100/cas/logout">退出登录</a>

但我们更希望退出登录后,能自动跳转到某个页面,那如何处理呢?
修改cas系统的配置文件cas-servlet.xml

 <bean id="logoutAction" class="org.jasig.cas.web.flow.LogoutAction"
        p:servicesManager-ref="servicesManager"
        p:followServiceRedirects="${cas.logout.followServiceRedirects:true}"/>

改为true后,可以在退出时跳转页面到目标页面,修改index.jsp的退出链接

<a href="http://localhost:9100/cas/logout?service=http://www.baidu.com">退出登录</a>
