02 搭建cas client完成單點登陸
上一節咱們搭建了cas server。這一節咱們將搭建兩個客戶端完成單點登陸的測試。html
一、前提約束
- 完成搭建cas server
https://www.jianshu.com/p/ed0c1359b82d
二、操做步驟
2.1 建立cas-client1，假設端口爲9001
- 建立maven的web工程，名字爲cas-client1，另外一個工程名稱爲cas-client2
https://www.jianshu.com/p/042073b7710b - 在pom.xml中加入如下依賴

- 在項目/src/main/resources下建立spring-mvc.xml
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">
<context:component-scan base-package="net.wanho.controller"></context:component-scan>
</beans>
- 在項目/src/main/java下建立net.wanho.controller包
- 在項目/src/main/java的net.wanho.controller包中建立UserController.java
package net.wanho.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import javax.servlet.http.HttpSession;
@Controller
public class UserController {
/**
* 退出api,這裏只須要提供一個api就行，不使用springmvc也是能夠的
*/
@RequestMapping("/logout")
public String logout(HttpSession session) {
session.invalidate();
return "redirect:http://localhost:8080/cas/logout?service=http://www.baidu.com";
}
}
- 在項目/src/main/webapp中建立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>江蘇萬和</title>
</head>
<body>
<%--第二個項目這裏改成client2，以示區分--%>
client1 歡迎來到萬和
<%=request.getRemoteUser()%>
<a href="/logout">退出</a>
</body>
</html>
2.2 以一樣的方式建立cas-client2，注意其中與client1不一樣的地方，假設端口爲9002
2.3 修改D:\Program Files\apache-tomcat-8.5.32\webapps\cas\WEB-INF\cas.properties，測試在退出之時能夠跳轉到其餘頁面
cas.logout.followServiceRedirects=true
2.4 測試
(1) 重啓cas server，啓動cas-client1，啓動cas-client2
(2)訪問http://localhost:9001，獲得如下界面
(3)輸入zhangli/123456，點擊「LOGIN」，跳轉到如下界面
(4)在另外一個標籤中訪問 http://localhost:9002，獲得如下界面
(5)在http://localhost:9002所在的界面上點擊「退出」，則跳到了百度首頁
(6)再次刷新http://localhost:9001，再次跳轉到了登陸界面
以上就是casserver集合casclient1，casclient2完成的單點登陸測試。java
