jasig cas单点登录配置笔记之二
cas客户端下载链接: http://downloads.jasig.org/cas-clients/
cas客户端指接入cas的web服务项目,作者用Tomcat6环境搭建一个简单web程序.
web程序的Context root为:testWeb1,
主要程序和配置文件为三个,
HelloWorld.java 这是一个标准servlet程序
web.xml 标准的web配置文件,
NewFile.jsp 一个标准的jsp文件
项目还需要引入cas-clients的jar文件,文件位于C:\Users\Administrator\Downloads\cas-client-3.1-release\cas-client-3.1\modules下
将这些文件都引入web项目.
然后,启动运行Tomcat6.环境为JDK1.6
在IE中输入地址:
http://localhost:8180/testWeb1/NewFile.jsp
跳转到Cas服务认证页面,输入用户名和密码
结果页面输出:
这是一个测试业务! 用户名per001
在IE中输入地址:
http://localhost:8180/testWeb1/servlets/servlet/HelloWorldExample
结果页面输出:
Hello World!per001
下面附上程序代码和配置文件内容:
HelloWorld.java内容:
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
import org.jasig.cas.client.authentication.AttributePrincipal;
public class HelloWorld extends HttpServlet {
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws IOException, ServletException
{
AttributePrincipal principal = (AttributePrincipal) request.getUserPrincipal();
String username = principal.getName();
response.setContentType("text/html");
PrintWriter out = response.getWriter();
out.println("<html>");
out.println("<head>");
out.println("<title>Hello World</title>");
out.println("</head>");
out.println("<body>");
out.println("<h1>Hello World!"+username+"</h1>");
out.println("</body>");
out.println("</html>");
}
}
NewFile.jsp内容:
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<%@ page import="org.jasig.cas.client.authentication.AttributePrincipal"%>
<!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>Insert title here</title>
</head>
<body>
这是一个测试业务!
<%
AttributePrincipal principal = (AttributePrincipal) request.getUserPrincipal();
String username = principal.getName();
%>
用户名<%=username %>
</body>
</html>
web.xml内容:
