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" %>
       
     
        
      
 
      
 ${message} 
      
 
      
        
      
        
      
        
      
            by Crunchify.com        
    
     

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;@Controllerpublic 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 = "
Next Random # is " + r + ". Generated on " + new Date().toString() + "";	        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！！！
