Persist on the network (with Retrofit)

There are many libraries that permit to generate REST service client easily. The one that I prefer is Retrofit.

So, I decide to integrate Kripton with Retrofit, just to use Kripton persistence mechanism in Retrofit library. I want to show you here how simple is to work with them.

For example, we want to consume the REST service at

https://jsonplaceholder.typicode.com/posts/

So we define a Post class with Kripton BindType annotation

@BindType
public class Post {
  public long userId;
  public long id;
  public String title;
  public String body;
}

We can define the REST client interface:

public interface JsonPlaceHolderService {
  @POST("/posts/")
  Call<List<Post>> getAllPost();
}

The code to consume the REST service is:

// create retrofit using Kripton converter factory
Retrofit retrofit = new Retrofit.Builder()
  .baseUrl(“https://jsonplaceholder.typicode.com/")
  .addConverterFactory(KriptonBinderConverterFactory.create())
  .build();
JsonPlaceHolderService service = Retrofit.create(JsonPlaceHolderService.class);
// consume service
Response<List<Post>> response = service.getAllPost().execute();

The integration between Kripton and Retrofit is done by KriptonBinderConverterFactoryconverter.
