            "authorityName": "ROLE_USER"
        }
    ]
}

i don't know how to conver authorityName to java class and get response

android code here

public class RetrofitClient {
    Retrofit retrofit = new Retrofit.Builder()
            .baseUrl("http://10.0.2.2:8080/api/")
            .addConverterFactory(GsonConverterFactory.create())
            .build();
    public RetrofitService retrofitService = retrofit.create(RetrofitService.class);
}

public class MainActivity extends AppCompatActivity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        RetrofitClient retrofitClient = new RetrofitClient();
        Call<User> call = retrofitClient.retrofitService.getProduct3("jin", "Token");

        call.enqueue(new Callback<User>() {
            @Override
            public void onResponse(Call<User> call, Response<User> response) {
                if(response.isSuccessful()){
                    Log.i("Tag", "Success : " + response.toString());
                    Log.i("Tag", "Success : " + response.body().toString());
                } else {
                    Log.i("Tag", "Failed");
                }
            }
            @Override
            public void onFailure(Call<User> call, Throwable t) {
                Log.d("Tag", "Failed" + t.getMessage());
            }
        });
    }

public interface RetrofitService {
    @GET("user/{userid}")
    Call<User> getProduct3(@Path("userid") String userid, @Header("Authorization") String token);
}

android user class

public class User {
    @SerializedName("userid")
    private String userid;
    @SerializedName("sex")
    private boolean sex;
    @SerializedName("height")
    private int height;
    @SerializedName("authorityDtoSet")
    private List<AuthorityDto> authorityDtoSet;

    @Override
    public String toString() {
        return "PostResult{" +
                "userid=" + userid +
                ", sex=" + sex +
                ", height='" + height + '\'' +
                ", authorityDtoSet='" + authorityDtoSet + '\'' +
                '}';
    }
}

public class AuthorityDto {
    AuthorityDto(){}
    private String authorityName;
}

i think User class(android) doesn't match response(Server) so i can't get data how can i get json list data from server? plz help
