post, post_entity_tag, post_recommend 테이블을 신설한다. entity_type은 Inquiry.targetId 패턴을 따라 FK 없이 enum+id 조합으로 폴리모픽 참조를 표현하며, content는 Hibernate 6.6 네이티브 JSON 매핑으로 jsonb 컬럼에 저장한다. - V30 마이그레이션: post/post_entity_tag/post_recommend 테이블 및 인덱스 - Post/PostEntityTag/PostRecommend 엔티티, PostCategory/EntityType enum - ErrorCode: POST_NOT_FOUND, ALREADY_RECOMMENDED, NOT_RECOMMENDED 추가 이슈 #116 Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01JNjhau1bE58LegkwKtPBq2
게시글 entityTags(공연/아티스트/음악 멘션)를 화면에 표시하려면 FE가 엔티티 ID만으로는 제목·부제·썸네일을 알 수 없다. BE가 응답 시점에 Concert/Artist/ReleaseGroup을 조인해 EntityCardResponse로 채워주는 EntityLookupService를 도입한다. 상세·목록·백링크·통합검색 응답에서 공통으로 재사용한다. - EntityCardResponse(type, id, title, subtitle, thumbnailUrl) DTO - EntityLookupService.findCards(): (type, id) 키 목록을 배치 조회, 삭제된 참조는 결과에서 조용히 제외 - EntityLookupServiceTest: 타입별 매핑·혼합 조회·삭제된 참조 제외 검증 이슈 #116 Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01JNjhau1bE58LegkwKtPBq2
게시글 작성 중 공연/아티스트/음악 발매를 본문에 인라인 멘션하기 위한 자동완성 API를 추가한다. type별로 기존 검색 로직(Concert 제목, Artist name/alias, ReleaseGroup 검색 쿼리)을 재사용하고 결과를 EntityLookupService의 카드 변환 로직으로 통일한다. - GET /api/mentions/search?type=&q=&limit= (인증 불필요) - ConcertRepository.searchByTitleForMention 추가 - EntityLookupService.toCard(...)를 패키지 접근으로 열어 MentionService에서 재사용 - SecurityConfig: GET /api/mentions/search permitAll 추가 - MentionService/MentionControllerTest: 타입별 위임·빈 결과 처리 검증 (컨트롤러 테스트는 프로젝트 컨벤션인 standaloneSetup + LocalValidatorFactoryBean 사용) 이슈 #116 Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01JNjhau1bE58LegkwKtPBq2
게시글 작성·조회·수정·삭제 API를 구현한다. Tiptap JSON 본문은 Spring
Boot 4의 기본 HTTP 컨버터가 Jackson 3(tools.jackson) 기반이라 Jackson 2
전용 타입(JsonNode/@JsonRawValue)을 요청·응답 DTO에 직접 쓸 수 없어
Object(런타임에는 Map/List)로 받고, 저장·응답 시 컨트롤러 계층과
무관한 별도의 Jackson 2 ObjectMapper로 문자열 변환한다.
- POST /api/posts, GET /api/posts/{id}, GET /api/posts,
PATCH /api/posts/{id}, DELETE /api/posts/{id}
- REVIEW/INFO 카테고리는 entityTags 1개 이상 필수(생성·수정 모두 최종
category 기준으로 검증), entityTags는 주어지면 전체 교체
- PostDetailResponse.isAuthor(비인증 시 false), isRecommended(비인증
시 null) — 인증 여부에 따라 다른 널 규약을 의도적으로 적용
- 조회 시 viewCount +1 (Concert.viewCount와 동일한 벌크 UPDATE 패턴)
- TiptapTextExtractor: Tiptap 문서 트리에서 텍스트 노드만 추출해
content_text(검색용 파생 컬럼)를 만든다
- SecurityConfig: GET /api/posts, GET /api/posts/** permitAll 추가
- PostService/PostController/TiptapTextExtractor 테스트 추가
(컨트롤러 테스트는 standaloneSetup + AuthenticationPrincipalArgumentResolver로
인증 사용자 시뮬레이션, Jackson 3 기본 컨버터가 테스트에서 쓰는
JsonNode/Object 필드를 못 읽어 MappingJackson2HttpMessageConverter를 명시 등록)

- Line 23: Add `@NotNull` alongside `@Valid` on the EntityTagRequest element type in
both PostCreateRequest.entityTags and PostUpdateRequest.entityTags, so null list

them to saveEntityTags.
In `@src/main/java/com/Coming/Backend/post/dto/PostUpdateRequest.java`:
- Around line 12-13: Update PostUpdateRequest.title by adding a nullable-aware

- Line 138: Update the comment lookup in the like-creation flow around
CommentService so soft-deleted comments are excluded before adding a like or
incrementing likeCount. Use the existing deleted-state field or repository query
mechanism to treat deleted comments as CommentNotFoundException, preserving

Reject like mutations for soft-deleted comments.
CommentService.like and CommentService.unlike load comments with findById without checking comment.isDeleted(). Because deletion is soft, both methods can still change the like record and likeCount for a deleted comment. toResponse sets only isLiked to null, so the changed like state remains hidden in listings.
When comment.isDeleted() is true, both methods must throw CommentNotFoundException or the defined deleted-resource exception before changing the like record or count.

Escape LIKE wildcards in the search term.
q goes into the LIKE pattern without escaping. A query of % matches every post, and _ matches any single character. The value is bound as a parameter, so this is a result-correctness defect, not SQL injection. Escape \, %, and _, and declare the escape character in PostRepository.searchPosts.
🐛 Proposed fix
- String likeQ = "%" + q.toLowerCase(Locale.ROOT) + "%";
+ String escaped = q.toLowerCase(Locale.ROOT)

%, and _ before being wrapped in the LIKE pattern, using ! as the escape
character. In PostRepository.searchPosts, add ESCAPE '!' to every LIKE :q

게시글 삭제 시 모든 종속 행에 외래 키와 삭제 규칙을 추가하세요.
DELETE /api/posts/{id}는 PostService.delete를 호출합니다. 이 메서드는 post_entity_tag 행만 삭제한 뒤 게시글을 삭제합니다. 따라서 이 경로에서는 태그 행이 남지 않지만, post_recommend와 comment 행은 남을 수 있습니다. comment_like.comment_id에도 외래 키가 없으므로 댓글 좋아요 행도 고아 행으로 남을 수 있습니다.
post_entity_tag.post_id와 post_recommend.post_id에는 post(id) ON DELETE CASCADE 외래 키를 추가하세요. comment.post_id에도 같은 외래 키를 추가하세요. comment_like.comment_id에는 comment(id) ON DELETE CASCADE 외래 키를 추가하세요.

텍스트 노드 경계에 공백을 강제로 추가하지 마세요.
인접한 text 노드는 하나의 단어나 문장을 분할할 수 있습니다. 예를 들어 "안녕"과 "하세요"를 "안녕 하세요"로 변환하면 원문이 변경됩니다.
인라인 text는 원문 그대로 연결하세요. 문단과 같은 블록 경계에서만 구분자를 추가하세요. 이 경우를 구분하는 테스트도 추가하세요.
이 동작은 검색용 content_text와 10,000자 검증 결과를 모두 변경합니다.

게시글이 삭제돼도 딸린 comment·comment_like·post_recommend 행이 정리되지 않아 orphan 데이터로 남는 문제를 수정한다. 이 저장소의 다른 마이그레이션은 전부 ON DELETE CASCADE 없는 FK만 사용하므로, DB 제약 대신 PostService.delete()에서 comment_like → comment → post_recommend → post_entity_tag → post 순으로 명시적으로 삭제한다. 같은 CommentRepository 변경에 묶여 댓글 목록 조회 정렬에 id 보조 정렬을 추가해 createdAt이 동일한 댓글이 페이지 경계에서 뒤섞이지 않도록 한다.

- content_text 글자수(1만자) 제한은 Tiptap JSON에서 추출한 텍스트만 검증해, 텍스트는 짧고 구조(attrs 등)만 방대한 요청으로 우회할 수 있었다. 직렬화된 content 원본 문자열 크기(5만자)에도 별도 상한을 둔다. - 게시글 통합 검색·멘션 자동완성에서 검색어에 포함된 %, _가 LIKE 와일드카드로 해석돼 결과가 부정확해지는 문제를 백슬래시 이스케이프로 수정한다. PostgreSQL의 LIKE 기본 이스케이프 문자가 \이므로 JPQL 쿼리 자체는 건드리지 않는다. - 같은 (entityType, entityId) 태그를 중복 요청하면 post_entity_tag에 중복 행이 쌓이던 문제를 생성 시 distinct 처리로 방지한다.

- entityTags 리스트에 null 원소가 오면 @Valid가 건너뛰어 PostService가 그대로 tag.entityType()을 호출해 NPE가 날 수 있었다. 원소 타입에 @NotNull을 추가해 요청 단계에서 거부한다. - PostUpdateRequest.title은 @SiZe만 있어 공백 문자열로 덮어쓸 수 있었다(생성 시엔 @notblank로 막혀 있음). null(미변경)은 허용하되 공백만 거부하도록 @pattern을 추가한다.

- CommentService.like/unlike가 삭제 여부를 확인하지 않아 소프트 삭제된 댓글에도 좋아요가 계속 쌓일 수 있었다. 삭제된 댓글이면 CommentNotFoundException을 던지도록 한다. - 좋아요·추천 카운트는 @Modifying 벌크 UPDATE로 DB 값만 갱신하고, 응답은 이미 로드해둔 stale 엔티티 값에 +1/-1 해서 계산했다. 동시 요청 시 실제 DB 값과 응답이 어긋날 수 있어, 갱신 직후 현재 값을 다시 조회해 응답한다 (CommentRepository.findLikeCountById, PostRepository.findRecommendCountById).

GET /api/search(통합 검색)가 permitAll 목록에 없어 비로그인 사용자가 401을 받고 있었다. 게시글 목록·상세 조회가 공개인 것과 일관되게 permitAll에 추가한다. 겸사겸사 이미 "/api/posts/**"에 포함되는 "/api/posts" 중복 나열도 정리한다. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01JNjhau1bE58LegkwKtPBq2

기존 로직은 텍스트 노드가 나올 때마다 무조건 공백을 끼워 넣어, 같은 문단
안에서 굵게 등 서식으로 나뉜 인접 텍스트("안녕"+"하세요")까지 "안녕
하세요"로 바꿔버렸다. 이는 검색용 content_text와 1만자 글자수 검증 결과를
원문과 다르게 왜곡시킨다. 문단 등 블록(텍스트가 아닌 컨테이너) 경계에서만
구분자를 넣도록 순회 로직을 바꾸고, 관련 테스트를 갱신한다.

- Around line 318-321: Update unrecommend in PostService to use a conditional
delete by userId and postId instead of deleting the loaded PostRecommend entity.
If the delete affects zero rows, throw NotRecommendedException; decrement the
post’s recommend count only when exactly one row is deleted.
- Around line 281-283: Update the post deletion flow around
commentLikeRepository.deleteByCommentIdIn and commentRepository.findIdsByPostId
so comment likes are deleted without constructing an unbounded IN parameter
list; use a bulk delete keyed by post ID through a subquery or process comment
IDs in bounded batches, while preserving the existing deletion behavior.

변경사항 요약
게시글(작성/조회/수정/삭제/추천/검색/백링크/트렌딩태그), 댓글·답글(작성/소프트삭제/좋아요), 엔티티 멘션 자동완성 기능을 포함한 게시판 도메인을 신규 추가했다. 관련 마이그레이션(V30, V31), SecurityConfig의 조회 API permitAll 설정, 전 계층 테스트가 함께 포함되었다.
검토 결과
🟡 warning
V30__create_post_tables.sql,V31__create_comment_tables.sql: post/comment 관련 테이블에 FK 제약이 전혀 없다(레포의 다른 마이그레이션 V1/V5/V8/V16은 FK를 사용). 이 때문에PostService.delete()가 게시글 삭제 시 해당 게시글의 댓글(comment)·댓글 좋아요(comment_like)·추천(post_recommend) 행을 정리하지 않아 orphan 데이터로 남는다.→ post_id/comment_id에 FK + ON DELETE CASCADE를 추가하거나,
PostService.delete()에서 연관 댓글·추천 데이터를 명시적으로 삭제하도록 보완 권장.PostService.java(validateContentTextLength): 본문 글자수 제한은 Tiptap JSON에서 추출한contentText(순수 텍스트) 기준으로만 검증되고, 원본content(jsonb) 자체의 크기에는 제한이 없다. 텍스트 노드는 짧지만 구조가 방대한 JSON을 보내면 1만자 제한을 우회해 큰 jsonb를 저장할 수 있다.→ content 직렬화 결과(JSON 문자열) 길이에도 상한을 두는 것을 권장.
