27.2 新建一个user_list.jsp文件;

<%@ 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>

<title>Insert title here</title>

</head>

<body>

用户添加成功<br>

username: ${user.username}<br>

password: ${user.password}<br>

age: ${user.age}<br>

sex: ${user.sex}

</body>

</html>

27.3 新建一个userController类，是实现模型属性值的添加和获得user对象;

package com.ask.controller;

import java.util.Map;

import org.springframework.stereotype.Controller;

import org.springframework.web.bind.annotation.ModelAttribute;

import org.springframework.web.bind.annotation.PathVariable;

import org.springframework.web.bind.annotation.RequestMapping;

import org.springframework.web.bind.annotation.RequestMethod;

import org.springframework.web.bind.annotation.RequestParam;

import com.ask.controller.entity.User;

//添加地址;

@RequestMapping("/user")

@Controller

public class UserController{

//使用模型属性值的添加;

@ModelAttribute

public void getUserParm(@RequestParam("username") String username,Map<String, Object> map){

if(username!=null){

User u=new User("scott", "tiger", 20, 1);

System.out.println(u);

map.put("user", u);

}

//获得user对象;

@RequestMapping(value="/add")

public String getUser(User user){

System.out.println(user);

return "user_list";

}
