How can i create instance of foo class from response's json-CodePudding

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

CodePudding user response：

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)
