创建HelloWorldController

package com.controller;
    import org.springframework.stereotype.Controller;
    import org.springframework.ui.Model;
    import org.springframework.web.bind.annotation.RequestMapping;
    import com.po.User;
    @Controller
    public class HelloWorldController {
    	@RequestMapping("/testForward")
    	public String testForward(Model model) {
    		User user=new User();
    		user.setUserName("baixue");
    		user.setPassWord("123");
    		model.addAttribute("user", user);
    		return "success";
    	}
    	@RequestMapping("/testRedirect")
    	public String testRedirect(Model model) {
    		User user=new User();
    		user.setUserName("baixue");
    		user.setPassWord("123");
    		model.addAttribute("user", user);
    		return "redirect:/success.jsp";
    	}
    }

创建index.jsp

<%@ page language="java" contentType="text/html; charset=utf-8"
        pageEncoding="utf-8"%>
    <!DOCTYPE html>
    <html>
    <head>
    <meta charset="utf-8">
    <title>index</title>
    </head>
    <body>
    	<a href="testForward">testForward</a>
    	<br>
    	<a href="testRedirect">testRedirect</a>
    </body>
    </html>

创建success.jsp

<%@ page language="java" contentType="text/html; charset=utf-8"
        pageEncoding="utf-8"%>
    <%@taglib prefix="c" uri="http://java.sun.com/jstl/core" %>
    <!DOCTYPE html>
    <html>
    <head>
    <meta charset="utf-8">
    <title>success</title>
    </head>
    <body>
    	用户名:${user.userName }
    	<br>
    	密码:${user.passWord }
    </body>
    </html>
