404 when trying to access post url with springboot

Question

Good evening, I have the code below with the implementation of a service Rest /teste123, and when calling this method from the angular-js code, already authenticated with the basic authentication of spring-boot I have access to this service. When I try to access it from the retrofit2 of my android or the Postman extension of Chrome, the two give error 404. Somebody explain to me what I’m doing wrong. Just to be clear that I am pointing to the correct ip of the pc which is 192.168.... and not to localhost at the time of the calls. Thank you.

@RestController
public class TesteController {
@RequestMapping(value = "/teste123", method = RequestMethod.POST)
public Programa gravaLote2(@RequestBody Programa programa) {
    System.out.println(programa);
    return new Programa();
} 
}

below the example of the angular-js code that works.

$http.post("/teste123", {id: 'asd', txtPrograma: 'adsadasd'})
        .then(function (response) {
            console.log(response);
        }, function (response) {
            console.log(response);
        })

Here the interface I used on android.

public interface ExecucaoService {

@POST("teste123")
public Call<Programa> gravaLote(@Body Programa programa);}

and to add credentials to the retrofit header I did as follows.

        private static OkHttpClient.Builder httpClient = new OkHttpClient.Builder();
private static Retrofit.Builder builder =
        new Retrofit.Builder()
                .baseUrl(baseUrlWS)
                .addConverterFactory(GsonConverterFactory.create());
        String credentials = username + ":" + password;
        final String basic = "Basic " + Base64.encodeToString(credentials.getBytes(), Base64.NO_WRAP);

        httpClient.addInterceptor(new Interceptor() {
            @Override
            public okhttp3.Response intercept(Interceptor.Chain chain) throws IOException {
                Request original = chain.request();

                Request.Builder requestBuilder = original.newBuilder()
                        .header("Authorization", basic)
                        .header("Accept", "application/json")
                        .method(original.method(), original.body());
                Request request = requestBuilder.build();
                return chain.proceed(request);
            }
        });
      OkHttpClient client = httpClient.build();
    Retrofit retrofit = builder.client(client).build();
    // retrofit.create(serviceClass); aqui pego a instancia do serviço criada.

here the image showing the success of the angle on the left and the problem on the right.

I still have hope that it is not retrofit or Postman problem, but a configuration that I did not do in sptring-boot.

According to the spring-boot documentation, for you to create a basic web application, you only need the spring-boot Parent and the spring-boot-Starter-web dependency. The most common mistake that happened to me at the beginning of my learning with spring-boot, was in relation to the wrong header that was sent in the request, but this caused me a 400 or 405. I don’t have much experience with android but as far as I could notice, this code snippet (@POST("executing/writingLote")) indicates that you are sending a post to the execution/writingLote address and may be causing the 404 error, because your address is /test123. I hope I’ve helped!
