JAVA 解析JSON格式数据

      1.解析JSON格式数据需要的JAR包:

      commons-beanutils.jar

      commons-collections-3.1.jar

      commons-lang-2.0.jar

      commons-logging.jar

      ezmorph-1.0.6.jar

      json-lib-2.4-jdk15.jar

      log4j-1.2.11.jar

      morph-1.1.1.jar

      附件提供下载。

    

      2. 解析数据核心代码（附件2有淘宝返回的JSON格式数据示例）

/**
     * 解析从淘宝返回的订单详情数据
     * @param jsonString：淘宝返回的JSON格式数据
     * @return：订单详情数据
     */
    public Order analyticJson(String jsonString){

        //JSON格式数据解析对象
        JSONObject jb = JSONObject.fromObject(jsonString);
        JSONObject ja = jb.getJSONObject("trade_fullinfo_get_response").getJSONObject("trade");

        //需返回的订单对象
        Order order = new Order();

        order.setBuyer_nick(ja.getString("buyer_nick"));
        order.setReceiver_address(ja.getString("receiver_address"));
        order.setReceiver_city(ja.getString("receiver_city"));
        order.setReceiver_name(ja.getString("receiver_name"));
        order.setReceiver_state(ja.getString("receiver_state"));

        //区域是否存在
        if(ja.containsKey("receiver_district")){
            order.setReceiver_district(ja.getString("receiver_district"));
        }else{
            order.setReceiver_district("");
        }
        //手机号是否存在
        if(ja.containsKey("receiver_mobile")){
            order.setReceiver_mobile(ja.getString("receiver_mobile"));
        }else{
            order.setReceiver_mobile("");
        }
        //电话是否存在
        if(ja.containsKey("receiver_phone")){
            order.setReceiver_phone(ja.getString("receiver_phone"));
        }else{
            order.setReceiver_phone("");
        }

        //订单明细列表
        java.util.List<OrderDetail> goodsList = new java.util.LinkedList<OrderDetail>();
        JSONArray orderDetailArr = ja.getJSONObject("orders").getJSONArray("order");

        //循环添加订单明细
        for(int j=0;j<orderDetailArr.size();j++){
            OrderDetail od = new OrderDetail();
            od.setNum(orderDetailArr.getJSONObject(j).getString("num"));
            od.setOuter_iid(orderDetailArr.getJSONObject(j).getString("outer_iid"));
            od.setPayment(orderDetailArr.getJSONObject(j).getString("payment"));
            goodsList.add(od);
        }
        order.setGoodsList(goodsList);

        return order;

    }
