简单的单点登录实现过程及效果展示

一、实现过程

从用到的jar包文件夹的cas-server-3.3.1modules中找出cas.war放到tomcat/webapps下面(cas-server-webapp-3.3.1.war重命名即可)。

现在cas默认的server端已经有了，下面自己写2个客户端测试一下

MyEclipse里面新建web project:sso

新建类HelloWorldExample

package servlet;

import java.io.IOException;

import java.io.PrintWriter;

import java.util.Enumeration;

import javax.servlet.ServletException;

import javax.servlet.http.HttpServlet;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

public final class HelloWorldExample extends HttpServlet {

public void doGet(HttpServletRequest request,

HttpServletResponse response)

throws IOException, ServletException {

response.setContentType("text/html");

PrintWriter writer = response.getWriter();

writer.println("");

writer.println("");

writer.println("");

writer.println("");

writer.println("");

writer.println("

");

writer.println("

");

writer.println("

");

writer.println("

");

writer.println("

");

writer.println("

"); writer.println(""); writer.println("

"); writer.println(" Sample Application Servlet "); writer.println("This is the output of a servlet that is part of"); writer.println("the Hello, World application."); writer.println("

");

writer.println("");

writer.println("");

}

}

在web.xml文件添加CASFilter与servlet映射。

xmlns="/xmls/j2ee"

xmlns:xsi="/2001/XMLSchema-instance"

xsi:schemaLocation="/xmls/j2ee

/xmls/j2ee/web-app_2_4.xsd">

CAS Filter

edu.yale.its.tp.cas.client.filter.CASFilter

edu.yale.its.tp.cas.client.filter.loginUrl

https://:8443/cas/login

edu.yale.its.tp.cas.client.filter.validateUrl

https://:8443/cas/serviceValidate

edu.yale.its.tp.cas.client.filter.serverName :8080

CAS Filter

/*

HelloWorldExample

servlet.HelloWorldExample

HelloWorldExample

/servlet/HelloWorldExample

同样，再建一个web project : sso1

HelloWorldExample与web.xml直接从sso中copy即可。

二、效果展示：

输入网址:8080/sso/servlet/HelloWorldExample会自动跳转到以下页面（https://:8443/cas/login?service=http%3A%2F%%3A8080%2Fsso%2Fservle t%2FHelloWorldExample）：

输入用户名和密码后（:8080/sso/servlet/HelloWorldExample?ticket=ST-1-FFcLusvRh9KSM3Jfaq5R-ca
