뷰테이블을 만들어서 맵핑하는 전략을 선택하셨군요. 이러면 DB가 바뀐다면 뷰테이블도 추가해줘야하는 불편함이 있을 것 같긴합니다.

성능상의 이슈로 인해 어쩔 수 없이 양방향 연관관계로 사용하는 것이 좋을 것 같습니다.. 내부에서는 양방향으로 사용하되, 외부에 PhotoItem을 숨기는 전략이 차선책일 것 같아요.

PhotoItem 클래스에서 photoId 대신 다대일 양방향(@manytoone) 관계를 사용하여 Photo 객체를 참조하자는 의미일까요?

넵 연관관계의 주인은 참조키를 가지고 있는 엔티티가 되어야 성능 상 이슈가 없다고 하네요..
