📌 개요 (Overview)

  • PR 브랜치: feature/sprint03-comment-u ➔ feature/sprint03-comment
  • 관련 이슈: [Feature]: 댓글 수정(Update) 기능 구현 [Feature]: 댓글 깊이와 아키텍처 #13
  • 작업 목적: 댓글 본문 수정 API(PUT /api/v1/comments/{commentId})와 3대 작성자 권한 검증(일반 회원, 로그인 익명, 비회원 익명) 로직을 구현하고, 원문 조작 방지를 위해 관리자 우회를 제외한 본인 전담 수정 정책 및 단위/통합 테스트를 검증함.

🛠️ 주요 변경 사항 (What Changed)

  1. DTO 정의 (backend/.../domain/comment/dto/)
  • CommentUpdateRequest: 본문(content) 필수 검증(@notblank, @SiZe(max = 1000)), 비회원 익명 수정용 anonymousPassword(선택).
  • CommentUpdateResponse: 클라이언트 렌더링에 필요한 commentId, content, updatedAt 필드 반환.
  1. 엔티티 수정 (Comment.java)
  • updateContent(String newContent) 메서드 추가: 영속성 컨텍스트 더티 체킹(Dirty Checking)을 통해 트랜잭션 커밋 시 UPDATE 쿼리 자동 발행 및 BaseTimeEntity의 updatedAt 갱신.
  1. 댓글 수정 비즈니스 로직 및 권한 검증 (CommentService.java)
  • updateComment: 댓글 존재 확인 및 Soft Delete 상태 검증(둘 다 COMMENT_001, 404 Not Found 반환).
  • validateUpdatePermission 3대 권한 검증:
    • 일반 회원 및 로그인 익명: 본인 세션(publicId) 일치 여부 검증 (타인 접근 시 AUTH_002, 403 Forbidden 반환).
    • 비회원 익명: passwordEncoder.matches(anonymousPassword, comment.getAnonymousPassword()) 검증 (비밀번호 누락 또는 불일치 시 POST_004, 403 Forbidden 반환).
    • 최고 관리자(ROLE_ADMIN) 우회 제외: 삭제(DELETE)와 달리 원작성자 본인만 수정 가능하도록 제한.
  1. 컨트롤러 엔드포인트 연동 (CommentController.java)
  • PUT /api/v1/comments/{commentId} 엔드포인트 연결 및 @Valid 요청 검증 적용.

💡 핵심 기술 의사결정 및 트레이드오프 (Technical Rationale)

  • 삭제 권한(관리자 허용)과 수정 권한(본인 한정)의 정책 분리:
    • 삭제(DELETE)는 음란물, 도배, 비방 등 커뮤니티 정화를 위해 최고 관리자(ROLE_ADMIN)의 강제 개입이 필수적임.
    • 반면 수정(PUT)은 관리자라 할지라도 타인의 발언 내용을 임의로 변경할 경우 원문 왜곡, 책임 소재 불분명, 신뢰도 훼손 문제가 발생하므로 오직 작성자 본인만 수정할 수 있도록 관리자 우회 권한을 엄격히 배제함.
  • JPA 더티 체킹(Dirty Checking) 기반 단일 책임 갱신:
    • 별도의 JPQL 벌크 쿼리 대신 엔티티 상태 변경 메서드(updateContent)를 호출하여 1차 캐시와 DB 상태를 동기화하고, JPA Auditing을 통해 updatedAt이 정확한 수정 일시로 갱신되도록 보장함.
  • 타입 기반 예외 처리 및 문자열 리터럴 배제:
    • 문자열 리터럴 예외 생성을 배제하고 ErrorCode Enum(COMMENT_001, AUTH_002, POST_004, COMMON_001)과 CustomAuthException으로 예외 처리를 일원화함.

🧪 테스트 및 검증 결과 (Verification & QA)

  • CommentUpdateTest (수정 기능 7개 시나리오 전수 검증):
    • [성공 1] 일반 회원 본인 댓글 수정 성공 (본문 갱신 및 updatedAt 반영 검증).
    • [성공 2] 비회원 익명 댓글 올바른 비밀번호 입력 시 수정 성공 검증.
    • [실패 1] 로그인 회원이 타인의 댓글 수정 시도 시 AUTH_002 (403 Forbidden) 차단 검증.
    • [실패 2] 비회원 익명 댓글에 잘못된 비밀번호 입력 시 POST_004 (403 Forbidden) 차단 검증.
    • [실패 3] 비회원 익명 댓글에 비밀번호 누락 후 수정 시도 시 POST_004 (403 Forbidden) 차단 검증.
    • [실패 4] 이미 Soft Delete된 댓글 수정 시도 시 COMMENT_001 (404 Not Found) 차단 검증.
    • [실패 5] 존재하지 않는 댓글 ID 수정 시도 시 COMMENT_001 (404 Not Found) 차단 검증.
  • 백엔드 테스트 검증: ./gradlew test --tests "CommentUpdateTest" 실행 결과 7/7건 통과 (BUILD SUCCESSFUL in 18s).
  • 코드 포맷팅: ./gradlew spotlessApply 서식 검증 완료.

✅ PR 체크리스트 (Checklist)

  • 코드가 정상적으로 빌드되고 모든 단위/통합 테스트가 통과하는지
  • DTO 생성 시 불필요한 가변성을 차단하고 Java Record 표준을 준수했는지
  • 문자열 리터럴 예외 대신 ErrorCode 기반 커스텀 예외로 일원화했는지
  • Controller ↔ Service ↔ Repository 간 계층 분리 원칙을 준수했는지
  • docs/conception/sprint03/ 하위 설계 문서(API 명세서 PUT 스펙)와 일치하는지
  • docs/project/work.md 작업 기록지가 최신 상태로 업데이트되었는지

The PR adds cursor-based comment and reply retrieval, structured comment responses, comment updates, reply-limit enforcement, pessimistic locking, integration tests, environment-backed database credentials, and expanded Gemini review workflow behavior.

Changes

Comment API and persistence

Layer / File(s) Summary
Comment contracts and domain behavior
backend/src/main/java/com/ikae/snowthing/domain/comment/dto/*, backend/src/main/java/com/ikae/snowthing/domain/comment/entity/Comment.java, database/ddl.sql, backend/src/main/java/com/ikae/snowthing/global/error/ErrorCode.java
Comment responses now include writer, anonymity, deletion, reply, and pagination metadata. Update DTOs, immutable collections, domain update methods, database indexes, and the 100-reply error code were added.
Cursor-based comment repository
backend/src/main/java/com/ikae/snowthing/domain/comment/repository/*
Custom JDBC queries now resolve cursors, retrieve root comments and replies, load five-item reply previews, count active replies, apply locking, and map visibility metadata.
Comment service and HTTP endpoints
backend/src/main/java/com/ikae/snowthing/domain/comment/service/CommentService.java, backend/src/main/java/com/ikae/snowthing/domain/comment/controller/CommentController.java
Comment reads now use cursor pagination and bounded previews. Creation validates locked parent roots and reply limits. Update endpoints validate content and authorize member or anonymous edits.
Comment validation and database support
backend/src/test/java/com/ikae/snowthing/domain/comment/*, backend/src/test/java/com/ikae/snowthing/domain/comment/service/*, .env.example, backend/src/main/resources/application.yml, docker-compose.yml, database/spike_seed_comments.sql, backend/src/main/java/com/ikae/snowthing/domain/comment/spike/CommentSpikeBenchmarkHarness.java
Integration tests cover reads, creation, updates, authorization, concurrency, limits, and error handling. Database credentials use environment variables. Seed operations use upserts, and partitioned EXPLAIN parsing accounts for an extra column.

Automated Gemini review workflow

Layer / File(s) Summary
Pull request review retrieval and posting
.github/workflows/gemini-review.yml
The workflow retrieves pull request metadata and the complete diff with gh, uses a Korean review prompt, targets gemini-2.5-flash, and posts a repository-scoped pull request comment.

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk: 🟠 High · up to 3c624

This PR adds public comment mutation while also changing repository automation and production database connection behavior. Unauthorized users can trigger privileged automation, anonymous comment passwords can be guessed repeatedly, and database traffic may be sent without encryption, creating material security and reliability risk; merge should wait for these issues to be fixed or explicitly accepted by the appropriate owners.

validateUpdatePermissionvalidateDeletePermission의 중복을 정리해 주세요.

두 메서드는 관리자 우회 블록(Line 285-291)을 제외하면 논리가 동일합니다. 익명 분기, 작성자 동일성 판정, 예외 코드까지 같은 코드가 두 벌 존재합니다.

권한 판정 로직의 중복은 정책 드리프트를 만듭니다. 예를 들어 위에서 지적한 getAnonymousPassword() == null 가드를 한쪽에만 추가하면 수정과 삭제의 동작이 갈라집니다. 감사 로그나 차단 회원 검사 같은 규칙이 추가될 때도 같은 문제가 반복됩니다.

관리자 우회 여부만 파라미터로 받는 단일 메서드로 통합하는 방식을 권장합니다.

♻️ 제안 리팩토링

호출부는 각각 validateWritePermission(comment, request.anonymousPassword(), userDetails, false)validateWritePermission(comment, anonymousPassword, userDetails, true)가 됩니다. "수정에는 관리자 우회가 없다"는 정책이 호출부에 한 줄로 드러나는 이점도 있습니다.

52-79: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

⚠️ 테스트 데이터소스 부트스트랩 코드가 두 클래스에 그대로 복제되었고, 예외 타입이 목적과 맞지 않습니다.

useRealMySqlrequiredEnvironmentVariable이 두 파일에 문자 단위로 동일하게 존재합니다. 공통 원인은 테스트 인프라 설정을 공유 지점 없이 각 테스트 클래스가 소유하고 있다는 점입니다.

두 가지 문제가 함께 발생합니다.

1. 설정 드리프트
댓글 테스트가 추가될 때마다 이 28줄이 복사됩니다. 이후 ddl-auto나 dialect를 한 곳에서만 수정하면, 클래스별로 서로 다른 스키마 전략으로 테스트가 돌아갑니다. 또 @DynamicPropertySource가 클래스마다 다른 프로퍼티를 등록하면 Spring이 별도의 ApplicationContext를 각각 생성합니다. 컨텍스트 캐시가 무효화되어 전체 테스트 실행 시간이 클래스 수에 비례해 늘어납니다.

2. 예외 타입 오용
requiredEnvironmentVariable은 환경 변수 누락 시 CustomAuthException(ErrorCode.INVALID_INPUT)을 던집니다. 이는 HTTP 400과 "잘못된 입력값입니다."라는 도메인 의미를 가진 예외입니다. 테스트 부트스트랩 실패에 이 예외를 쓰면 CI 로그에 인증 오류처럼 표시되어, 원인이 "환경 변수 SNOWTHING_TEST_DB_PASSWORD 누락"임을 알 수 없습니다. 도메인 예외를 인프라 실패에 재사용하면 예외 타입이 전달하는 정보가 소실됩니다.

수정 대상:

  • backend/src/test/java/com/ikae/snowthing/domain/comment/service/CommentCreateTest.java#L52-L79: useRealMySqlrequiredEnvironmentVariable을 제거하고, 공통 설정 클래스를 상속하거나 @ContextConfiguration으로 참조하도록 변경하세요.
  • backend/src/test/java/com/ikae/snowthing/domain/comment/service/CommentUpdateTest.java#L45-L72: 동일하게 제거하고 같은 공통 설정을 참조하세요. 두 클래스가 같은 프로퍼티 집합을 사용하면 ApplicationContext도 재사용됩니다.

MySQL Connector/J sslMode parameter values useSSL deprecated allowPublicKeyRetrieval security warning

💡 Result:

In MySQL Connector/J, the sslMode property is the current standard for configuring SSL/TLS connections, while older properties like useSSL have been deprecated [1][2]. sslMode Parameter Values The sslMode property determines the level of SSL security. The supported values are: DISABLED: Establish unencrypted connections [1][3]. PREFERRED: Establish encrypted connections if the server supports it; otherwise, fall back to unencrypted (this is the default) [1][4]. REQUIRED: Establish secure connections if the server supports it, or fail the connection [1][5]. VERIFY_CA: Similar to REQUIRED, but also validates the server's TLS certificate against configured Certificate Authority (CA) certificates [1][3]. VERIFY_IDENTITY: Similar to VERIFY_CA, but additionally verifies that the server's certificate matches the hostname used for the connection [1][6]. Deprecated Properties Legacy connection properties such as useSSL, requireSSL, and verifyServerCertificate are deprecated [1][2]. While the driver still accepts them, they are ignored if sslMode is explicitly set [1][3]. If not explicitly set, the driver translates legacy settings into an equivalent sslMode value [1][4]. allowPublicKeyRetrieval and Security Warnings The "Public Key Retrieval is not allowed" error typically occurs when using the caching_sha2_password authentication plugin (the default in MySQL 8+) over an unencrypted connection [7]. To authenticate securely, the driver requires the server's RSA public key to encrypt the password [7]. allowPublicKeyRetrieval=true permits the client to automatically request the public key from the server [8][7]. This is considered a security risk because it exposes the client to potential Man-in-the-Middle (MitM) attacks, where an attacker could intercept the key exchange [7][9]. It is recommended to use encrypted connections (SSL/TLS) instead of enabling allowPublicKeyRetrieval=true, as SSL protects the password exchange without needing to retrieve the public key insecurely [7][9]. If you must use this parameter, it should generally be reserved for development environments only [7].

🗄️ Data Integrity & Integration | 🟠 Major | ⚡ Quick win

멱등성 확보는 좋습니다. 다만 실패가 조용한 덮어쓰기로 바뀌었습니다.

💡 ON DUPLICATE KEY UPDATE 도입으로 시드 스크립트를 반복 실행할 수 있게 된 점은 좋습니다. 스파이크 벤치마크는 조건을 바꿔 여러 번 돌려야 하는데, 이전처럼 중복 키 오류로 중단되면 매번 수동 정리가 필요합니다. password_hashpassword 컬럼명 변경도 Member 엔티티 매핑과 일치합니다.

⚠️ 다만 이 변경으로 동작 성격이 바뀌었습니다. 이전에는 member_id = 1이 이미 존재하면 중복 키 오류로 즉시 실패했습니다. 이제는 기존 행의 nickname'스파이크테스터'조용히 덮어씁니다. post_category 역시 category_id = 1name을 덮어씁니다.

💥 [장애/영향 시나리오]

  • 이 스크립트는 대상 스키마를 검사하지 않습니다. docker-compose.yml이 초기화하는 snowthing 스키마에 그대로 실행하면, 실제 member_id = 1 회원의 닉네임이 '스파이크테스터'로 교체됩니다. 해당 회원이 작성한 모든 게시글과 댓글의 표시 이름이 한꺼번에 바뀝니다.
  • 원본 닉네임은 어디에도 보존되지 않으므로 복구가 불가능합니다. 오류 메시지도 없어 변경 사실 자체를 인지하기 어렵습니다.
  • 개발자 로컬 DB와 스파이크 DB를 같은 인스턴스에서 운용하는 경우 특히 발생 확률이 높습니다.

🛠️ [개선 권장]

시드가 자기 소유 행에만 작용하도록 만들거나, 대상 스키마를 명시적으로 제한하세요. public_id로 소유권을 표시하면 실수로 실제 회원을 건드리지 않습니다.

🛠️ 소유권 기반 시드로 변경

이후 프로시저에서 member_id = 1을 하드코딩하고 있다면, SELECT member_id FROM member WHERE public_id = 'member-spike-001'로 조회해 변수에 담아 사용하세요. 파일 상단에 "스파이크 전용 스키마에서만 실행" 문구를 주석으로 남기는 것도 도움이 됩니다.

[질문] 이미 @Transactional인 메서드 안의 기본 transactionTemplate은 새 트랜잭션이 아니라 기존 트랜잭션에 참여합니다. 회원 조회와 BCrypt까지 같은 범위이므로 시작 지점 재설계나 별도 Bean 분리가 필요하지 않을까요?

[질문] 버전 검사 없이 수정해 동시 요청이면 마지막 요청이 앞선 변경을 덮어씁니다. last-write-wins 의도가 아니라면 @Version이나 수정시각 조건부 업데이트를 검토해주세요. last write wins가 무엇인지도 찾아보면 좋겠네요
