类的某属性类型是json对象,怎么处理

1.在开发过程中, 处处可见json对象, 请求参数类型是json, 响应参数类型是json. 要记住怎么封装. 

 

小案例1.

public class EleQueryRefundRsp {
　　private Integer code;
　　private String message;
　　private Object data;

　　setter/getter/toString

 

public class demo01 {
    private static final Logger logger = LogManager.getLogger(demo01.class);

    public static void main(String args[]) {
        EleQueryRefundRsp aa= new EleQueryRefundRsp();
        aa.setCode(200);
        aa.setMessage("成功");

        Map<String, Object> resultMap = new HashMap();
        resultMap.put("amount", 200);
        resultMap.put("trade_no",1007201812);
        resultMap.put("status",1);

        aa.setData(resultMap);
        
        logger.info("测试~" + aa);
        
    }

}

控制台打印: 
测试~aa[code=200, message=成功, data={amount=200, trade_no=1007201812, status=1}]

 

 

 

 

 

 

2.用具体对象接收

public class QueryOrderInfoRsp {
    private GoodsInfo goods_info;
    
    setter/getter/toString
}

public class GoodsInfo {
    private String ele_order_id;// 订单号
    private String refund_order_id;// 退款订单号
    private Long refund_amount;// 退款金额
    private String refund_time;// 退款时间
    private String subject;// 商品标题

   setter/getter/toString
}

QueryOrderInfoRsp object = new JsonObject(message.getBody()).mapTo(QueryOrderInfoRsp.class);

// String ele_order_id = object.getGoods_info().getString("ele_order_id");
String order_id = object.getGoods_info().getEle_order_id();
String refund_order_id = object.getGoods_info().getRefund_order_id();
Long refund_amount = object.getGoods_info().getRefund_amount();
String refund_time = object.getGoods_info().getRefund_time();
String subject = object.getGoods_info().getSubject();
