spring error Error creating bean with name 'XXX' define in file (다른 entity의 id를 repository를 통해 가져올 수 없음)

Question

안녕하세요. 현재 product의 id를 ReviewService에서 사용하려고 reviewRepository에 다음과 같이 작성을 하였습니다. 아래는 에러 코드와 reviewrepository, review entity, review service, product entity의 id 선언 부분입니다. 에러코드org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'reviewController' defined in file [C:\Users\개인정보\shoppingmall\product\controller\ReviewController.class]: Unsatisfied dependency expressed through constructor parameter 0: Error creating bean with name 'reviewService' defined in file [C:\Users\개인정보\shoppingmall\product\service\ReviewService.class]: Unsatisfied dependency expressed through constructor parameter 0: Error creating bean with name 'reviewRepository' defined in io.elice.shoppingmall.product.repository.ReviewRepository defined in @EnableJpaRepositories declared on JpaRepositoriesRegistrar.EnableJpaRepositoriesConfiguration: Could not create query for public abstract java.util.List io.elice.shoppingmall.product.repository.ReviewRepository.findByProductId(java.lang.Long);

} }이렇게 해서 실행을 했는데 다음과 같이 에러가 발생하면서 수정을 할 수 없었습니다. 구글에 검색을 해보니 카멜케이스로 작성하지 않아서 그렇다고 하는데 현재 repository에 적은 메서드 명 말고도 다양한 카멜케이스로 바꾸어봤는데 해결되지 않아 여기에 올리게 되었습니다. 이외에도 spring구조상으로 잘못 코드가 작성된 부분들 등 코드를 잘못 작성한 곳들이 있다면 피드백 반영하겠습니다!

감독님테스트가하고싶어요 · Answer

@Repository public interface ReviewRepository extends JpaRepository { List findByProductId(Long id); }find / By / Product / Id위에 근거해서 jpa는 review 엔티티에서 에서 product를 찾았고,그 이후 product 엔티티에서 에서 id를 찾을텐데 id가 없네요?@Id @Column(name = "productId") @GeneratedValue(strategy = GenerationType.IDENTITY) private long productId;이렇게 선언해두셨으니 findByProductProductId(Long id) 로 하면 될 것 같네요.
