Robię swoje pierwsze kroki w Spring Boot, a teraz przez jakiś czas utknąłem z następującym problemem.Autowiring repozytorium DynamoDB w aplikacji Spring Boot przy użyciu danych sprężystych
bramki
Chcę, aby przechowywać dane aplikacji w DynamoDB na AWS korzystających Wiosna danych. W tym celu powinna istnieć jedna usługa, która zawiera wszystko, co związane z trwałością. Kod powinien być tak prosty i czytelny, jak to tylko możliwe. Dlatego staram się unikać konfiguracji XML i zamiast tego używać adnotacji.
problem
wiosną nie autowire wystąpienie składu w DataService (NoSuchBeanDefinitionException).
AKTUALIZACJA: Test integracji ma również zależność od repozytorium przy użyciu @Autowire (patrz poniżej) i również się nie udaje. Próbowałem także stworzyć fikcyjną implementację interfejsu repozytorium i oznaczyć ją jako @Component - co również działa dobrze.
Dlatego zakładam, że Spring nie może znaleźć implementacji DynamoDB repozytorium w mojej konfiguracji. Przyczyna tego jednak nie rozumiem. Cała dokumentacja mówi mi, że po prostu muszę zdefiniować interfejs repozytorium i pozwolić, aby Spring Data zrobiła magię.
