Passing different data to same name json attribute in retrofit model

问题

  1. public class Response {
  2.     private boolean success;
  3.     private String message;
  4.     private Data data;
  6.     public boolean isSuccess() {
  7.         return success;
  8.     }
  10.     public String getMessage() {
  11.         return message;
  12.     }
  14.     public Data getData() {
  15.         return data;
  16.     }
  17. }
  19. public class Data {
  20.     // Define fields based on the possible data themes
  21.     // For the first data theme
  22.     private String update_status;
  23.     private String last_version_name;
  24.     private String last_version_code;
  25.     private boolean need_to_upgrade;
  27.     // For the second data theme
  28.     private String year;
  29.     private String month;
  30.     private String day;
  31.     private String hour;
  32.     private String second;
  33.     private String unix;
  35.     // Generate getters for each field
  36.     // ...
  37. }

There is a WebService which i want to @GET and @POST data from it, but all of its responses are like this theme:

  1.  {
  2.   "data": {
  3.     ...
  4.   },
  5.   "success": ... ,
  6.   "message": ...
  7. }

but there are different output themes of data, like these:

  1. {
  2.   "data": {
  3.     "update_status": "critical",
  4.     "last_version_name": "1.0.3",
  5.     "last_version_code": "3",
  6.     "need_to_upgrade": false
  7.   },
  8.   "success": true,
  9.   "message": "DONE!"
  10. }

&

  1. {
  2.   "data": {
  3.     "year": "2020",
  4.     "month": "09",
  5.     "day": "09",
  6.     "hour": "06",
  7.     "second": "00",
  8.     "unix": "1599631246"
  9.   },
  10.   "success": true,
  11.   "message": null
  12. }

How can i define models to use this via Retrofit and GSON Converter?
Should i use @SerializedName somewhere?

(i.e:)

  1. public class Response{
  2.     private boolean success;
  3.     private String message;
  4.     
  5.     //private Data data
  6. }

创建一个基础合约，并通过所有响应类进行扩展。在合约中，data 部分将是通用的。

  1. public class BaseResponse<T> {
  2.     public boolean success;
  3.     public String message;
  4.     public T data;
  5. }

现在，你需要为每种类型的响应创建数据类。

  1. public class MyResponse {
  2.     public String update_status;
  3.     public String last_version_name;
  4.     public String last_version_code;
  5.     public boolean need_to_upgrade;
  6. }

现在你可以将 BaseResponse<MyResponse> 用作 Retrofit 调用的返回类型。对于数组响应，你也可以做同样的事情，即创建一个 BaseListResponse 类。

英文:

Create a Base Contract and extend it by all of the response classes. in Contract data part will be Generic.

  1. public class BaseResponse&lt;T&gt; {
  2. public boolean success;
  3. public String message;
  4. public T data;
  5.  }

Now you have to create data class for each type of response.

  1. public class MyResponse{
  2. public String update_status;
  3. public String last_version_name;
  4. public String last_version_code;
  5. public boolean need_to_upgrade;
  6. }

Now you can use BaseResponse&lt;MyResponse&gt; as return type of retrofit call. You can do the same for Array response i.e create a BaseListResponse class.
