fix: 명소 조회 user null 수정 -> user fetch join

[ggamnunq]

Summary by CodeRabbit

• Refactor
  • 장소 목록 조회 시 좋아요와 사용자 정보를 한 번에 가져오도록 데이터 접근을 최적화했습니다. 목록/상세 화면 로딩이 더 빨라지고 스크롤 시 끊김이 줄며, 대규모 목록에서도 안정적인 반응 속도를 제공합니다.
  • 좋아요 수 계산과 내가 누른 좋아요 표시가 더 일관되게 반영되어, 간헐적인 지연이나 미표시 현상이 감소합니다.

Walkthrough

PlaceLikeRepository의 다건 조회 메서드를 JOIN FETCH로 대체하여 User를 즉시 로딩하도록 변경했고, PlaceQueryService는 해당 새 메서드를 사용하도록 수정되었습니다. 그 외 로직과 반환 타입은 동일합니다.

Changes

Cohort / File(s)	Summary
Repository: fetch join for likes src/main/kotlin/busanVibe/busan/domain/place/repository/PlaceLikeRepository.kt	기존 findAllByPlaceIn(...) 제거. @Query와 JOIN FETCH(pl.user)를 사용하는 findAllByPlaceInFetchUser(@Param("placeList") ...) 추가. 기존 findLikeByPlace는 변경 없음.
Service: method rename usage src/main/kotlin/busanVibe/busan/domain/place/service/PlaceQueryService.kt	getPlaceList에서 레포 메서드 호출을 findAllByPlaceIn(...) → findAllByPlaceInFetchUser(...)로 교체. 나머지 집계/판단 로직은 동일.

Poem

당근 같은 귀로 퐁퐁, 깡총깡총 뛰며 말해요 🥕
좋아요 찾기, 이제 한 번에 척!
사용자도 함께 데려오는 춤사위
지연 없이 척척, 캐시처럼 똑딱
부산의 바이브, 조인으로 반짝!
