Jpa 커스텀 리포지토리 다중 상속 문제

커스텀 리포지토리 사용중 문제가 발생하여 질문 드립니다. @Repository public interface UserRepository extends JpaRepository<User, Long>, CustomRepository { Optional<User> findByUserId(String userId); } public interface CustomRepository { Long search(User user); } public class ACustomRepositoryImpl implements CustomRepository { @Override public Long search(User user) { return 1L; } } 이런식으로 코드를 작성하고 실행 시키면 아래와 같은 에러 메시지가 나옵니다. 그런데 ACustomRepositoryImpl 구현체 이름을 CustomRepositoryImpl 이렇게 바꾸면 정상적으로 실행됩니다. 명명규칙이 그저 개발자들 간의 약속 인줄 알았는데 규칙을 무조건 지켜야 하는 건지 궁금하여 질문 드렸습니다.
