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 = "http://www.mamicode.com/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!!!
