楼上已经给你实体类了，还有解析方法，用gson你的数据解析成bean对象的时候会遇到问题哦，你的字符串中有null，会解析出错，在初始化gson对象的时候要这样写
Gson gson = new GsonBuilder().serializeNulls().create();

用GSON来解析，放在一个对象里面，里外曾一层层对象解析，这个问题很基础吧

把data后面的大括号里的所有元素可以提取成一个对象bean，用fastJson/GSON直接解析成对象
info同理，可以直接解析成一个对象的数组

key都固定的吧？一个jsonobject.里面三个元素data info status，data里面有个labels包含两个元素的JSONArray，info里面包含两个元素的JSONArray
