浅谈ajax在jquery中的请求和servlet中的响应

在jsp中，首先，你需要导入jquery的架包：

获取可返回站点的根路径：

<% 
  String path = request.getContextPath(); 
%> 

在jquery中写ajax请求：

jsp部分：

 
    
     
 
 
  
序号
 
  
业主名
 
  
金额
 

     
 
    
  

在servlet中用到了阿里巴巴的快速转换json的包com.alibaba.fastjson.JSON：

private void queryevaluateByuserId(HttpServletRequest request, HttpServletResponse response) throws SQLException, IOException, ServletException{
			HttpSession session=request.getSession();
			request.setCharacterEncoding("UTF-8");
			response.setContentType("text/html");
			response.setCharacterEncoding("UTF-8");
			cookie[] cookies = request.getcookies();
			int ownerId = 0;
			for (int i = 0; i < cookies.length; i++) {
	      cookie cookie = cookies[i];
	      if (cookie.getName().equals("ownerId")) {
	      	ownerId = Integer.parseInt(cookie.getValue()); 
	      }
			}
			List orderList = new ArrayList<>();
			List queryevaluateList = new ArrayList<>();
			orderList = orderServiceImpl.queryOrderList(ownerId, null, null, null, null, null);
			List> workers = new ArrayList>(); 
			for(int i = 0;i < orderList.size();i++){
				Map order = new HashMap();
				order.put("description", orderList.get(i).getDescription());
				order.put("name", orderList.get(i).getOwnerName());
				System.out.println(orderList.get(i).getDescription());
				order.put("type",orderList.get(i).getTypeName());
				queryevaluateList = orderServiceImpl.queryevaluateListByUserId(orderList.get(i).getId());
				order.put("comment", queryevaluateList.get(0).getComment());
				List allocation = orderServiceImpl.queryAllocationByOrderId(orderList.get(i).getId());
				order.put("price", String.valueOf(allocation.get(0).getPrice()));
				 System.out.println(order);
				workers.add(order);
			}
     //将map键值对转换成json，传给jsp
     response.getOutputStream().write(JSON.toJSonBytes(workers));
		}
