android Refitfit无法解析数据，将数据变为空

Question

{
  "loginj": [
    {
      "JUser_Id": "20",
      "JFullName": "aaa",
      "JEmail": "[e-mail]"
    }
  ]
}

 public static APIInterface getInterfaceService() {

    Gson gson = new GsonBuilder()
            .setLenient()
            .create();

    Retrofit retrofit = new Retrofit.Builder()
            .baseUrl(BASE_URL)
            .addConverterFactory(GsonConverterFactory.create(gson))
            .build();

    final APIInterface mInterfaceService = retrofit.create(APIInterface.class);
    return mInterfaceService;
}

public class Loginj {
   private String JUser_Id;
   private String JFullName;
   private String JEmail;
}

回调类APIInterface

Call<Loginj> login(@Body User user);

得到回应

Call<Loginj> loginResponseCall = apiInterface.login(user);
loginResponseCall.enqueue(new Callback<Loginj> () {
      @Override
      public void onResponse(Call<Loginj>  call, Response<Loginj>   response) {
            if (response.isSuccessful()) {
                   Loginj bodywValue = response.body();
                   Toast.makeText(getApplicationContext(),""+bodywValue.getJFullName(),
                                              Toast.LENGTH_SHORT).show();
             }
      }

      @Override
      public void onFailure(Call<Loginj>  call, Throwable t){}

备选办法1：

这里您的响应在数组中，您需要像这样更改

{
  "JUser_Id":"20",
 "JFullName":"aaa",
 "JEmail":"[e-mail]"
}

备选案文2：

public class RestResponse {
 public List<Loginj> loginj;
}

Call<RestResponse> loginResponseCall = apiInterface.login(user);
            loginResponseCall.enqueue(new Callback<RestResponse> () {
                @Override
                public void onResponse(Call<RestResponse>  call, Response<RestResponse>   response) {
                    if (response.isSuccessful()) {
                        RestResponse body = response.body();
                        Loginj bodywValue = body.loginj.get(0);
                        Toast.makeText(getApplicationContext(),""+bodywValue.getJFullName(),Toast.LENGTH_SHORT).show();
                    }}

                    @Override
                    public void onFailure
                    (Call<RestResponse>  call, Throwable t){

                    }
