인프런 커뮤니티 질문&답변

안녕하세요! 제가 지금 진행 중인 프로젝트가 있는 데 어려움을 겪어서 질문 드립니다!

queryDsl을 사용해서 DTO로 바로 조회도 되고 값이 담겨져 있는 것도 로그를 찍어서 확인할 수 있습니다. 근데 PostMan이나 스웨거로 값을 반환받았을 때 isAuthenticated 값은 잘 채워져서 나오는 데 CulturalEventDetail값이 자꾸 null로 반환이 됩니다! 아무리 찾아봐도 답이 안 나와서 질문 드립니다..

아래는 코드 입니다!

@Getter
@Builder
@NoArgsConstructor
@AllArgsConstructor
@ToString
public class CulturalEventDetailsResponseDTO  {


    private CulturalEventDetail culturalEventDetail;
    private boolean isAuthenticated;

}



public CulturalEventDetailsResponseDTO getCulturalEventDetails(final int culturalEventId, final int userId) {

        return queryFactory.select(Projections.fields(CulturalEventDetailsResponseDTO.class, culturalEvent.culturalEventDetail, visitAuth.isAuthenticated))
                .from(culturalEvent)
                .leftJoin(visitAuth)
                .on(
                        culturalEvent.id.eq(visitAuth.culturalEvent.id),
                        visitAuth.user.id.eq(userId))
                .where(
                        culturalEvent.id.eq(culturalEventId)
                )
                .fetchOne();
        }

public CulturalEventDetailsResponseDTO getCulturalEventDetails(final int culturalEventId, final User user) {

        final CulturalEventDetailsResponseDTO culturalEventDetails = culturalEventQueryRepository.getCulturalEventDetails(culturalEventId, user.getId());
        culturalEventRepository.updateVisitCount(culturalEventId);
        log.info("culturalEventDetails = {}", culturalEventDetails);
        return culturalEventDetails;
    }
