📝 WalkthroughWalkthroughThe 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. ChangesComment API and persistence
Automated Gemini review workflow
Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🟠 High · up to 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.

validateUpdatePermission과validateDeletePermission의 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() == null가드를 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.

⚠️ 테스트 데이터소스 부트스트랩 코드가 두 클래스에 그대로 복제되었고, 예외 타입이 목적과 맞지 않습니다.
useRealMySql과requiredEnvironmentVariable이 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. 이후ddl-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 시CustomAuthException(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 변수SNOWTHING_TEST_DB_PASSWORD누락"임을 알 수 없습니다. 도메인 예외를 인프라 실패에 재사용하면 예외 타입이 전달하는 정보가 소실됩니다.수정 대상:

Inline comments:
In @.env.example:
- Around line 7-9: Extend the .env.example database test configuration with
SNOWTHING_TEST_DB_URL, and document that its value must be supplied as a process
environment variable before running tests because backend/build.gradle does not
load .env. Ensure the guidance explicitly covers both CommentCreateTest and
CommentUpdateTest, including their H2 fallback when the variable is absent.
In @.github/workflows/gemini-review.yml:
- Around line 33-35: Update the workflow’s gh pr view and gh pr diff handling to
explicitly check each command’s exit status before processing output; avoid
allowing head to mask gh pr diff failures, and only treat an empty diff as valid
after the GitHub CLI command succeeds.
- Line 38: Update the PR diff handling in the workflow so it does not silently
truncate output at 12,000 bytes. Process the complete diff in hunks or per-file
chunks, or, if that cannot be done, explicitly mark the review as partial and
publish the list of omitted files.
- Line 51: Update the Gemini review prompt in the workflow so PR title, body,
and diff are clearly treated as untrusted data rather than instructions, using
supported system-instruction configuration for review policy and explicit
delimiters around the PR content.
- Line 14: Update the workflow condition around the issue_comment trigger to
require both the existing pull-request and /gemini-review checks and an approved
commenter identity or team allowlist before running Gemini or using pull-request
write permissions; reject unauthorized commenters and add coverage verifying
repeated unauthorized requests do not execute the workflow.
In
`@backend/src/main/java/com/ikae/snowthing/domain/comment/controller/CommentController.java`:
- Around line 57-63: 익명 댓글의 비밀번호 대입을 제한하도록 CommentService의
validateUpdatePermission과 validateDeletePermission에 공통 분산 원자 카운터, 시도 제한 및 잠금 또는
지연을 적용하고, 인증 성공 시 해당 카운터를 초기화하세요. ClientIpResolver는 신뢰된 프록시 범위에서만
X-Forwarded-For를 사용하도록 설정하며, 댓글 생성 검증에는 최소 길이와 충분한 엔트로피를 요구하도록 추가하세요.
In `@backend/src/main/java/com/ikae/snowthing/domain/comment/entity/Comment.java`:
- Around line 108-110: Update CommentService.updateComment to call
commentRepository.flush() after Comment.updateContent() and before constructing
CommentUpdateResponse, and extend Comment.updateContent() to reject null, blank,
and content exceeding the 1000-character column limit before assignment.
Apply the same fix in
`@backend/src/main/java/com/ikae/snowthing/domain/comment/service/CommentService.java`
around lines 229 - 232.
In
`@backend/src/main/java/com/ikae/snowthing/domain/comment/repository/CommentRepositoryImpl.java`:
- Around line 72-77: Unify soft-deleted reply handling across findRootComments,
findTopReplyPreviews, findReplies, and countActiveReplies; use the existing
active-only policy by applying is_deleted = false consistently so replyCount,
hasMoreReplies, previews, and paginated replies describe the same set. Add or
update an integration test covering mixed and fully deleted replies, and reuse a
shared preview-limit constant if the repository supports it.
In `@backend/src/main/resources/application.yml`:
- Line 67: Update the JDBC URL configuration for the docker and prod profiles to
enforce TLS, preferably with sslMode=VERIFY_IDENTITY and the required
truststore; if certificate verification is not yet available, use
sslMode=REQUIRED. Remove useSSL=false and set allowPublicKeyRetrieval=false for
those profiles, while leaving the local profile unchanged.
In
`@backend/src/test/java/com/ikae/snowthing/domain/comment/CommentReadTest.java`:
- Around line 209-214: 댓글 조회의 페이지 크기 검증에서 사용하는 전용 에러 코드를 추가하고,
CommentService.validateReadSize가 1~50 범위를 벗어날 때 INVALID_INPUT 대신 이를 반환하도록 변경하세요.
CommentReadTest의 잘못된 크기 검증도 새 에러 코드를 기대하도록 갱신하되, PostService에서 사용하는
INVALID_PAGE_SIZE와 그 1~100 계약은 변경하지 마세요.
In `@database/spike_seed_comments.sql`:
- Around line 12-16: Update the seed statements for post_category and member so
reruns only update rows owned by the spike seed, rather than silently
overwriting arbitrary records with IDs 1. Use the existing identifying value
public_id = 'member-spike-001' to resolve and target the member, and restrict
the category update to the spike seed’s own row or explicitly limit execution to
the dedicated spike schema.
In `@docker-compose.yml`:
- Around line 10-12: Synchronize the database username contract by updating the
application.yml local and docker/prod profile username settings to use
SNOWTHING_DB_USERNAME, matching the MYSQL_USER configuration in the Compose
service. Preserve snowuser as the default behavior when the environment variable
is unset.

SNOWTHING_TEST_DB_URL을 .env.example에 추가하고 환경변수 전달 방법을 명시하세요.
CommentCreateTest와 CommentUpdateTest는 SNOWTHING_TEST_DB_URL이 없으면 실제 MySQL 설정을 등록하지 않고 H2 datasource를 사용합니다. 또한 backend/build.gradle은 .env 파일을 로드하지 않으므로, 테스트 실행 전에 값을 프로세스 환경변수로 전달해야 합니다.
설명도 두 테스트를 모두 명시하세요.

Spring Data JPA AuditingEntityListener @LastModifiedDatewhen is updated during entity lifecycle flush@PreUpdate official documentation
💡 Result:
In Spring Data JPA, the AuditingEntityListener uses JPA lifecycle events to manage fields annotated with @LastModifiedDate [1][2]. The auditing process is specifically integrated with the @PrePersist and @PreUpdate lifecycle phases [3]. When an entity is updated, the @PreUpdate callback—which is triggered by the AuditingEntityListener—is invoked before the actual update operation is executed against the database [4][3]. Because these auditing updates are applied at this stage, the @LastModifiedDate field is automatically populated just before the SQL update statement is performed [3][5]. It is important to note the following regarding this lifecycle: 1. Timing and Flushing: The auditing update occurs during the flush process when the persistence context synchronizes with the database [4][5]. If you are performing operations that bypass the JPA persistence context—such as using JPQL or native @Query updates with @Modifying—the auditing lifecycle events are not triggered [6][7]. In these cases, the @LastModifiedDate will not be automatically updated because the entity instances themselves are not being processed by the EntityManager [6][7]. 2. Dependency on Lifecycle: Because auditing relies on the standard JPA lifecycle (persist, merge, update) [6], any manual updates performed via bulk repository queries will require manual handling of audit fields, as the AuditingEntityListener is only active for entities managed directly by the EntityManager [6][4]. In summary, the @LastModifiedDate is updated during the @PreUpdate lifecycle phase, which occurs automatically as part of the flush operation when managing entities through standard repository methods like save [4][3][5].

업데이트 응답 전에 JPA flush를 수행하세요
CommentService.updateComment는 Comment.updateContent() 직후 CommentUpdateResponse를 생성합니다. updatedAt은 @LastModifiedDate와 AuditingEntityListener가 flush 중 실행하는 @PreUpdate에서 갱신되므로, 응답에 이전 값이 들어갈 수 있습니다. 응답 생성 전에 commentRepository.flush()를 호출하고, 테스트에서 기존 값보다 이후인지 검증하세요.
CommentUpdateRequest의 검증은 컨트롤러 경로에만 적용됩니다. Comment.updateContent()가 @Column(length = 1000) 불변식을 직접 보장하지 않으면, 검증을 우회한 호출이 flush 시 DataIntegrityViolationException을 일으킬 수 있습니다. 엔티티에서 null·공백·최대 길이를 검증하세요.

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].

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_hash → password 컬럼명 변경도 Member 엔티티 매핑과 일치합니다.
member_id = 1이 이미 존재하면 중복 키 오류로 즉시 실패했습니다. 이제는 기존 행의 nickname을 '스파이크테스터'로 조용히 덮어씁니다. post_category 역시 category_id = 1의 name을 덮어씁니다.
💥 [장애/영향 시나리오]
- 이 스크립트는 대상 스키마를 검사하지 않습니다.
docker-compose.yml이 초기화하는snowthing스키마에 그대로 실행하면, 실제member_id = 1회원의 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

+ON DUPLICATE KEY UPDATE `nickname` = VALUES(`nickname`);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.

환경 변수 필수 지정(:?) 도입은 적절합니다. 다만 MYSQL_USER만 구성 가능해져 애플리케이션 설정과 어긋납니다.
${SNOWTHING_DB_ROOT_PASSWORD:?...}와 ${SNOWTHING_DB_PASSWORD:?...}는 Compose의 required-variable 문법입니다. 변수가 없으면 컨테이너 기동 전에 오류가 발생하므로, 빈 비밀번호나 기본 비밀번호로 DB가 올라가는 상황을 구조적으로 차단합니다. 자격 증명 외부화의 올바른 구현입니다.
${SNOWTHING_DB_USERNAME:-snowuser}로 구성 가능하게 바뀌었습니다. 반면 backend/src/main/resources/application.yml은 username: snowuser를 여전히 하드코딩합니다(local 프로필 Line 42, docker/prod 프로필 Line 66). 두 값이 하나의 계약인데 한쪽만 변수화되었습니다.
💥 [장애/영향 시나리오]
운영자가 SNOWTHING_DB_USERNAME=appuser를 지정하면 다음 순서로 진행됩니다.
- MySQL 컨테이너는
appuser계정을 생성하고,snowuser는 생성하지 않습니다. - 애플리케이션은 여전히
snowuser로 접속을 시도합니다. - HikariCP가
Access denied for user 'snowuser'@'%'로 실패하고, 커넥션 풀 초기화 실패로 컨테이너가 기동하지 못합니다.
.env.example이 SNOWTHING_DB_USERNAME=snowuser를 제시하므로 기본 경로에서는 드러나지 않습니다. 즉 이 결함은 "기본값을 바꾼 순간에만" 나타나며, 원인이 설정 불일치라는 점을 파악하기까지 시간이 걸립니다. 변경 가능해 보이는 설정이 실제로는 변경 불가인 상태는 운영 사고의 흔한 원인입니다.
🛠️ [개선 권장]
애플리케이션 쪽 username도 같은 변수로 통일하세요.
🛠️ 사용자명 계약 통일
backend/src/main/resources/application.yml의 두 프로필을 수정합니다.
datasource:
url: jdbc:mysql://mysql:3306/snowthing?...
driver-class-name: com.mysql.cj.jdbc.Driver
- username: snowuser
+ username: ${SNOWTHING_DB_USERNAME:snowuser}
password: ${SNOWTHING_DB_PASSWORD}또는 반대로, 사용자명을 구성 대상으로 삼지 않겠다면 docker-compose.yml에서 변수화를 되돌려 계약을 하나로 유지하세요.
- MYSQL_USER: ${SNOWTHING_DB_USERNAME:-snowuser}
+ MYSQL_USER: snowuser이 경우 .env.example의 SNOWTHING_DB_USERNAME 항목과 SNOWTHING_TEST_DB_USERNAME 항목도 함께 정리해야 합니다.
