Spring Ajax一个简单样例

配置不说了。要在前面helloworld的样例基础上弄。

相同在hello下新建ajax.jsp

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

    pageEncoding="UTF-8"%>

<%@ page isELIgnored ="false" %>

<!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>Spring MVC Example with AJAX call</title>

<style type="text/css">

body {

    background-image:

        url('http://cdn3.crunchify.com/wp-content/uploads/2013/03/Crunchify.bg_.300.png');

}

</style>

<script type="text/javascript"

    src="http://code.jquery.com/jquery-1.10.1.min.js"></script>

<script type="text/javascript">

    function crunchifyAjax() {

        $.ajax({

            url : 'ajaxtest.html',

            success : function(data) {

                $('#result').html(data);

            }

        });

    }

</script>

<script type="text/javascript">

    var intervalId = 0;

    intervalId = setInterval(crunchifyAjax, 3000);

</script>

</head>

<body>

 <div align="center">

        <br> <br> ${message} <br> <br>

        <div id="result"></div>

        <br>

        <p>

            by <a href="http://crunchify.com">Crunchify.com</a>

        </p>

    </div>

</body>

</html>

创建Controller：

package com.cqu.tutorial;

import java.util.Date;

import java.util.Random;

import org.springframework.stereotype.Controller;

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

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

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

import org.springframework.web.servlet.ModelAndView;

@Controller

public class SpringAjaxJQuery {

	 @RequestMapping("/ajax")

	    public ModelAndView helloAjaxTest() {

	        return new ModelAndView("ajax", "message", "Crunchify Spring MVC with Ajax and JQuery Demo..");

	    }

	    @RequestMapping(value = "/ajaxtest", method = RequestMethod.GET)

	    public @ResponseBody

	    String getTime() {

	        Random rand = new Random();

	        float r = rand.nextFloat() * 100;

	        String result = "<br>Next Random # is <b>" + r + "</b>. Generated on <b>" + new Date().toString() + "</b>";

	        System.out.println("Debug Message from SpringAjaxJQuery Controller.." + new Date().toString());

	        return result;

	    }

}

最重要的一个问题就是import包的时候，ModelAndView引入的包是

import org.springframework.web.servlet.ModelAndView;

不要搞错了！！！
