跳ajax方式进行前后台交互之后台代码要怎么写

 1 package com.zq.www.mis.action;

18     @Result(name = "show", location = "/BacksAdmin/order_approve/list.jsp"),
19     @Result(name = "shenhes", location = "/BacksAdmin/order_approve/list.jsp")
20
21 })
22 public class Order1Action extends BaseAction{
23     @Autowired
24     private TorderManagerDAO dao;
25     List<String[]> orderlist;

42     this.ajaxSendJson(orderlist, true);   //我封装了代码
43     return null;
44     }
45     //这个函数将对应参数的的支付状态修改为"已退款"
46     public String shenhe() throws Exception{
47     System.out.println("id="+id);
48     dao.updateStatus(id);
49     this.ajaxSendSuccess();
50     return null;
51     }
52     //批量修改
53     public String shenhes() throws Exception
54     {
55     System.out.println("ajaxtext="+ajaxtext);
56     String[] a=ajaxtext.split(",");
57     for(int i=1;i<a.length;i++)
58     {
59         System.out.println("拆开的值是;"+a[i]);
60         dao.updateStatus(Integer.parseInt(a[i]));
