Mam kontroler
@RestController
public class CheckUserDataRestController {
private final UserSearchService userSearchService;
@Autowired
public CheckUserDataRestController(final UserSearchService userSearchService) {
this.userSearchService = userSearchService;
}
...
}
który autowired bean serwis
@Service("userSearchService")
public class UserSearchServiceImpl implements UserSearchService {
private final UserRepository userRepository;
private final AuthorizationService authorizationService;
@Autowired
public UserSearchServiceImpl(
@NotNull final UserRepository userRepository,
@NotNull final AuthorizationService authorizationService
) {
this.userRepository = userRepository;
this.authorizationService = authorizationService;
}
...
}
który natomiast autowired bean serwis
@Service("authorizationService")
public class AuthorizationServiceImpl implements AuthorizationService {
private final UserSearchService userSearchService;
@Autowired
public AuthorizationServiceImpl(final UserSearchService userSearchService) {
this.userSearchService = userSearchService;
}

Błąd jest spowodowany tym, że usługa UserSearchService jest automatycznie uwierzytelniana(autowired) w kontrolerze i usłudze AuthorizationService. Jak zapobiec temu błędowi? W kontrolerze parametr 0 konstruktora prowadzi do UserSearchService , w tym serwisie parametr 1 konstruktora prowadzi do AuthorizationService. Natomiast w tym serwisie parametr 0 konstruktora prowadzi znowu do UserSearchService . Czyli UserSearchService jest @Autowired w kontrolerze i serwisie AuthorizationService. Dlatego powoduje błąd, ale nie wiem dlaczego tak się dzieje.
