删除gson JsonObject中不需要的信息

Question

我有一个JSONObject响应，如

{
    "0:"{
        "name": "name1",
        "surname": "surname1",
        "id": "22",
        "motivations": []
    },
    "1:"{
        "name": "name2",
        "surname": "surname2",
        "id": "23",
        "motivations": []
    },
    "2:"{
        "name": "name3",
        "surname": "surname3",
        "id": "24",
        "motivations": []
    },
    "sign": "9e46b7d6b140b",
    "last_call": 1446
}

我想将它映射到List<Person>，但在删除之前我无法执行此操作 "0:","1:","2:" ,"sign":"9e46b7d6b140b","last_call":1446。

知道如何在模型中映射它吗？

Answer 1

创建Person类

class Person{
        String name;
        String surname;
        String id;
        String[] motivations;
         //Create getter setter for it
    }

创建HashMap<String,Object> map = new HashMap<>();

map = new Gson().fromJson(responseData, HashMap.class);

最后迭代地图

Iterator entries = map .entrySet().iterator();

while (entries.hasNext()) {
   String value = (String )entries.next().getValue();
 Object p;
 try{ 
    p = new Gson().fromJson(value , Person .class);
    \\person class
  }
  catch(Exception e)
  {
    // catch exception
    p =null;
  }
  if(p!= null && p instanceOf Person)
  {
     \\create list and add it to the separate list 
    \\ entries.next().getKey()
    \\ entries.next().getValue()
  }
}
