ajax - 在Ajax响应中获取整个页面: Spring MVC, Ajax

Question

我正在处理 ajax 请求/响应来更新表，

但是当 Ajax 调用 Controller 时，我得到了整个页面的响应。但我想要的只是需要用 c:forEach 表映射的精确表数据。谢谢。

Jsp View :

      <script type="text/javascript">
       jQuery(document).ready(function(){
           function doAjaxPost() {
                // get the form values
    var contextPath ='<jsp:expression>contextPath</jsp:expression>';

                $.ajax({
                    type: "GET",
                    url: contextPath+"/noticesAjaxRequest",
                    dataType: "json",
                    contentType: 'application/json',
                    success: function(data){
                        // we have the response
                        $('#info').empty().html(data);

                    },

                    });

                }
          setInterval(doAjaxPost,10*1000);
       });

    </script>  

       <div id="info">
        <c:forEach  items="${noticeForm.noticeList}" var="notice">
            <c:out value="${notice.coreValue} "/>
            <c:out value="${notice.description} "/>
            <br/>
        </c:forEach>
   </div> 

Controller :

@Controller
public class DashboardController {

private NoticeBO noticeBO;

/*@RequestMapping("/dashboardTest")
public String printWelcome(ModelMap model) {
    List<Employee> employeeList=dashboardDAO.getAllEmployee();
    for(Employee employee:employeeList)
    model.addAttribute("msg", model.get("msg")+"<br/> Spring 3 MVC Hello World"+employee.getCustomerId());

    return "DashboardTest";

}*/

public NoticeBO getNoticeBO() {
    return noticeBO;
}

public void setNoticeBO(NoticeBO noticeBO) {
    this.noticeBO = noticeBO;
}

@RequestMapping("/dashboard")
public String dashboard(ModelMap model) {
    return "Dashboard";
}

@RequestMapping("/notices")
public ModelAndView notices(@ModelAttribute("NoticeForm") NoticeForm noticeForm, ModelMap model) {

    noticeBO.prepareNoticeList(noticeForm,model);

    return new ModelAndView("notices","noticeForm",noticeForm);
}

@RequestMapping("/noticesAjaxRequest")
public ModelAndView noticesAjaxRequest(@ModelAttribute("NoticeForm") NoticeForm noticeForm, ModelMap model) {

    noticeBO.prepareNoticeList(noticeForm,model);

    return new ModelAndView("notices", "noticeForm", noticeForm);
}
}

更新{1}:

我尝试更改 Controller ，但它开始出现错误:[object XMLHttpRequest]

 @RequestMapping("/noticesAjaxRequest")
public @ResponseBody List<Notice> noticesAjaxRequest(@ModelAttribute("NoticeForm") NoticeForm noticeForm, ModelMap model) {

    noticeBO.prepareNoticeList(noticeForm,model);

    return noticeForm.getNoticeList();
}

感谢各位 friend 的帮助。最好、最简单的方法是创建单独的 jsp View ，并在从 Controller 返回/响应时包含该 View 。

jQuery(document).ready(function(){
           function doAjaxPost() {
                // get the form values
               var contextPath ='<jsp:expression>contextPath</jsp:expression>';

                $.ajax({
                    type: "GET",
                    url: contextPath+"/noticesAjaxRequest",
                    success: function(data){
                        // we have the response

                         $('#info').html(data); 
                        /* $('#info').refresh(); */
                    },

                     error: function(e){
                        alert('Error: ' + e);
                    } 
                    });
                }
          setInterval(doAjaxPost,10*1000);
       });

Controller :

@RequestMapping(value="/noticesAjaxRequest")
public  ModelAndView noticesAjaxRequest(@ModelAttribute("NoticeForm") NoticeForm noticeForm, ModelMap model) {

    noticeBO.prepareNoticeList(noticeForm,model);

    return new ModelAndView("/noticesList","noticeForm",noticeForm);
}
