实际上。我遇到了从我的Jsp到我的Spring MVC控制器的第一个ajax调用。我从互联网上获得了这个例子,http://maxheapsize.com/2010/07/20/spring-3-mvc-ajax-and-jquery-magic-or-better-simplicity/

Ajax javascript函数为:

<script type="text/javascript" src="scripts/jquery.js"></script>
<script type="text/javascript">
  function doAjax() {
    $.ajax({
      url: 'time.html',
      data: ({name : "me"}),
      success: function(data) {
        $('#time').html(data);
      }
    });
  }
</script>

HTML as:

<button id="demo" onclick="doAjax()" title="Button">Get the time!</button>
<div id="time">
</div>

和MVC控制器:

package com.maxheapsize.springmvc3.controller;

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.RequestParam;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.servlet.ModelAndView;
import java.util.Date;

@Controller
public class HelloWorldController {

  @RequestMapping("/hello")
  public ModelAndView helloWorld() {
    return new ModelAndView("hello", "message", "Spring MVC Demo");
  }

  @RequestMapping(value = "/time", method = RequestMethod.GET)
  public @ResponseBody String getTime(@RequestParam String name) {
    String result = "Time for " + name + " is " + new Date().toString();
    return result;
  } 
}

从MVC控制器,您可以看到请求映射是“/ time”。通常,如果我们从JSP调用控制器,我们只需要调用/ time来访问控制器,但我不明白,为什么我必须从Ajax url:function调用'time.html'?有什么不同?为什么?

请有人向我解释一下!
