创建HelloWorldController

package com.controller;
    import org.springframework.stereotype.Controller;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.servlet.ModelAndView;
    import com.po.User;
    @Controller
    public class HelloWorldController {
    	@RequestMapping("/ModelAndViewTest")
    	public ModelAndView ModelAndViewTest(ModelAndView mv) {
    		User user=new User();
    		user.setUserName("baixue");
    		user.setPassWord("123456");
    		//将user对象添加到ModelAndView
    		mv.addObject("user", user);
    		//设置要转发的页面
    		mv.setViewName("success");
    		return mv;
    	}
    }

创建User

package com.po;
    public class User {
    	private String userName;
    	private String passWord;
    	public String getUserName() {
    		return userName;
    	}
    	public void setUserName(String userName) {
    		this.userName = userName;
    	}
    	public String getPassWord() {
    		return passWord;
    	}
    	public void setPassWord(String passWord) {
    		this.passWord = passWord;
    	}	
    }

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="ModelAndViewTest">ModelAndViewTest</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>
