@FeignClient всегда вызывает резервный метод даже после получения ответа

/ 08 апреля 2020

Я пытаюсь получить информацию из другого сервиса, используя FeignClient. Оба зарегистрированы в Консуле. Это мой код. 

@Service
@FeignClient(name = "TESTSERVICE", fallback = TestClientImpl.class)
public interface TestClient {

    @GetMapping("/v1/api/get")
    Optional<Object> testMethod();
}

@Service
public class TestClientImpl implements TestClient {

    @Override
    public Optional<Object> testMethod() {
        return Optional.empty();
    }
}

application.yml 

hystrix:
  command:
    default:
      execution:
        isolation:
          strategy: SEMAPHORE
#          thread:
#            timeoutInMilliseconds: 160000000

feign:
  hystrix:
    enabled: true
#  client:
#    config:
#      default:
#        loggerLevel: full
#        connectTimeOutMillis: 160000000
#        readTimeOutMillis: 160000000

Почему FeignClient всегда вызывает метод возврата и возвращает Optional.empty () даже после успешного получения ответа ?
