[FIXED] How can i create instance of foo class from response's json

Issue

I'am using okhttp to operate on api requests but i've no idea how to create instance of pojo class from JSON response.

Solution

You can use gson/Jackson library to deserialise response. Consider the service you are calling returns below response

{
 "data": {"name": "Foo", "id": 1}
}

Then your POJO/models would look like

public class ServiceResponse {
   private Data data;
}

public class Data {
  private String name;
  private int id;
}

And your simple OkHttp client call is like

Response response = client.newCall(request).execute();

Then you can deserialise response using Jackson like this

ServiceResponse = new ObjectMapper().readValue(response.body().string(), ServiceResponse.class)
