spring mvc 和ajax异步交互完整实例代码

spring MVC 异步交互demo：

1.jsp页面：

<%@ page language="java" contentType="text/html; charset=utf-8"

pageEncoding="utf-8"%>

2.controller：

package xm.zjl.controller;

import java.io.IOException;

import java.util.HashMap;

import java.util.Map;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

import org.springframework.stereotype.Controller;

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

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

/**

* 登录controller

*

* @author Administrator

*

*/

@Controller

@RequestMapping("/user/*")

public class LoginController {

@RequestMapping(value="login.do")

public @ResponseBody Map login(HttpServletRequest request,HttpServletResponse response) throws IOException{

System.out.println(request.getParameter("name"));

Map map = new HashMap();

if(request.getParameter("name").equals("123")){

System.out.println("城东");

map.put("msg", "成功");

}else{

System.out.println("失败");

map.put("msg", "失败");

}

return map;

}

}
