Ответ на модификацию верен, но нет выборки данных в serverDB

У меня проблема с анализом данных через мой API. мой код модернизации отправлял истинное состояние в моем ответе, но если я ищу свой ServerDb, ответ не приходит.

API:

         @POST("/api/Database/NewLocation")
                Call<MapDetails> mapDetailLocation(@Body MapDetails 
mapDetails);

Детали карты:

    public class MapDetails {

    private String serialNumber;
    private String coordinate1;
    private String coordinate2;
    private String dateTime;
    private String speed;
    private Integer Port;

    public String getSerialNumber() {
        return serialNumber;
    }

       public void setSerialNumber(String serialNumber) {
           this.serialNumber = serialNumber;
       }

       public String getCoordinate1() {
           return coordinate1;
       }

       public void setCoordinate1(String coordinate1) {
           this.coordinate1 = coordinate1;
       }

       public String getCoordinate2() {
           return coordinate2;
       }

       public void setCoordinate2(String coordinate2) {
           this.coordinate2 = coordinate2;
       }

       public String getDateTime() {
           return dateTime;
       }

       public void setDateTime(String dateTime) {
           this.dateTime = dateTime;
       }

       public String getSpeed() {
           return speed;
       }

       public void setSpeed(String speed) {
           this.speed = speed;
       }

       public Integer getPort() {
           return Port;
       }

       public void setPort(Integer port) {
           Port = port;
       }

       public MapDetails(String serialNumber, String coordinate1, String                      
           coordinate2, String dateTime, String speed, Integer port) {
           this.serialNumber = serialNumber;
           this.coordinate1 = coordinate1;
           this.coordinate2 = coordinate2;
           this.dateTime = dateTime;
           this.speed = speed;
           Port = port;


       }
   }

Модернизация

          public class RetrofitClient {
       private static  final  String BASE_URL = "http://58.69.149.164:9114";
       private static RetrofitClient mInstance;
       private Retrofit retrofit;

       private RetrofitClient() {
           retrofit = new Retrofit.Builder()
            .baseUrl(BASE_URL)
            .addConverterFactory(GsonConverterFactory.create())
            .build();
       }
       public static  synchronized  RetrofitClient getmInstance(){
           if (mInstance==null){
               mInstance=new RetrofitClient();
           }
           return mInstance;
       }
       public Api getApi(){
           return  retrofit.create(Api.class);
       }

                    Retrofit retrofit = builder.build();

                    Api locate = retrofit.create(Api.class);

                    SetMapLocationApiCaller(locate, mapDetails);


                }

                private void SetMapLocationApiCaller(Api locate, MapDetails 
            mapDetails) {

                    Call<MapDetails> call = 
               locate.mapDetailLocation(mapDetails);
                    executeCallAsynchronously(call);
                }

                        }
                    });

Ответ здесь "истина" означает, что транзакция верна .. но на моем сервере db данные не получены .....

также мой api:

    if I send that, i will having a response from my serverDb...
