自己搭建tomcat服务器生成json数据，并用android客户端获取

服务端index.jsp：

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>







	
 json test 
	
<%@ taglib prefix="json" uri="http://www.atg.com/taglibs/json" %>


  
  
  
    
      
      
      
      
      
    
    
      
      
      
      
      
    
  

服务端生成的json：

{"itemCount":"100","subtotal":"$15.50","items":[{"title":"The big book of foo","description":"it does not work","imageUrl":"http://www.baidu.com","price":"$100","qty":"1"},{"title":"The big book of foo2","description":"it does not work2","imageUrl":"http://www.baidu.com2","price":"$1002","qty":"12"}]} 

android端解析代码：
