Я использую Jhipster для создания 2 микросервисов. Один микросервис вызывает другой микросервис с помощью FeignClient, но когда я пытаюсь протестировать первый микросервис, он выдает ошибку, я думаю, что причина в FeignClient. Что в этих случаях рекомендуется делать? Любая рекомендация будет признательна

Резервный ресурс

 @PostMapping("/reservations") public ResponseEntitylt;?gt; createReservation(@RequestBody Reservation reservation){   Reservation result = reservationService.saveReservation(reservation);   return ResponseEntity  .created(new URI("/api/reservations/"   result.getId()))  .headers(HeaderUtil.createEntityCreationAlert(applicationName, true, ENTITY_NAME, result.getId().toString()))  .body(result); }  

Служба резервированияимпл

Этот класс вызывает функцию FeignClient перед сохранением бронирования.

 @Override public Reservation saveReservation(Reservation reservation) {  roomFeignClient.updateRoomByNumber(reservation.getRoom());   return save(reservation); }  

Резервация ресурсов

Тестовый класс автоматически генерируется Jhipster

Вот сообщение об ошибке, когда я запускаю тест
