//    import com.yonyou.sscip.gson.Gson;

//   jSONObject 数据 {"pk_org":"TEST","pk_group":"TEST","code":"a","name":"a"}
      //1、创建Gson对象
        Gson gson = new Gson();
        //2、调用toJson(Object)将对象转为字符串
        String JsonStr = gson.toJson(json);
        System.out.println(JsonStr );
        //3、将json字符串封装为java对象[json字符串 的属性名要和javabean的属性一样]
        User user2 = gson.fromJson(json, User.class);

上面代码为JSONObject数据直接转换

如果参数是JSONString格式需要先转换为JSONObject格式

//JSONString数据转为JSONObject
JSONObject jObject = JSON.parseObject(json.toJSONString());
