通过改造解析json数据

Question

我在json对象中获得了动态的密钥数量，它将根据我使用的改造数据进行更改

JSON

{
"response_message": "Settings has been displayed successfully",
"deliveryCharges": [
  {
    "iSettingId": 2,
    "vSettingDescription": "deliveryCharges",
    "vSettingName1": 1,
    "vSettingName2": 1.5,
    "vSettingName3": 1.75,
    .
    .
    .
    "vSettingNamen": 1.75
  },
  {
    "iSettingId": 3,
    "vSettingDescription": "deliveryCharges",
    "vSettingName1": 1,
    "vSettingName2": 1.5,
    "vSettingName3": 1.75,
    .
    .
    .
    "vSettingNamen": 1.75
  },
  {
    "iSettingId": 4,
    "vSettingDescription": "deliveryCharges",
    "vSettingName1": 1,
    "vSettingName2": 1.5,
    "vSettingName3": 1.75,
    .
    .
    .
    "vSettingNamen": 1.75
  }
]
}

这里我可以获得n个vSettingName。它是完全动态的，所以我怎样才能为此制作POJO

Answer 1

试试这个

Gson gson = new Gson();
Type mapType = new TypeToken<List<Map<String, String>>>(){}.getType(); //define generic type
List<Map<String, String>> result = gson.fromJson(deliveryCharges,mapType);
