Gson: How to exclude specific fields from Serialization without annotations

Question

I\'m trying to learn Gson and I\'m struggling with field exclusion. Here are my classes

public class Student {    
  private Long                id;
  privat         


        

Answer 1

I'm working just by putting the @Expose annotation, here my version that I use

compile 'com.squareup.retrofit2:retrofit:2.0.2'
compile 'com.squareup.retrofit2:converter-gson:2.0.2'

In Model class:

@Expose
int number;

public class AdapterRestApi {

In the Adapter class:

public EndPointsApi connectRestApi() {
    OkHttpClient client = new OkHttpClient.Builder()
            .connectTimeout(90000, TimeUnit.SECONDS)
            .readTimeout(90000,TimeUnit.SECONDS).build();

    Retrofit retrofit = new Retrofit.Builder()
            .baseUrl(ConstantRestApi.ROOT_URL)
            .addConverterFactory(GsonConverterFactory.create())
            .client(client)
            .build();

    return retrofit.create  (EndPointsApi.class);
}
