이슈 #118: 약관 변경 이메일 고지 시스템의 기반이 되는 정책 버전 메타데이터(PolicyDocument)를 도입하고, 관리자가 새 정책 버전을 등록하는 POST /api/admin/policies API를 추가한다. 원문 전체는 프론트엔드가 SSOT로 관리하므로 detailUrl로만 연결한다. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01JNjhau1bE58LegkwKtPBq2
이슈 #118: User의 agreed_terms/agreed_privacy boolean 필드를 대체할 UserPolicyAgreement(userId, policyId, agreedAt) 이력 테이블을 추가한다. 마이그레이션에서 레거시 PolicyDocument(TERMS/PRIVACY, version=legacy)를 시드하고, 기존에 agreed_terms/agreed_privacy=true였던 유저의 동의 이력을 agreed_at 기준으로 백필한다. 로컬 DB에 다른 브랜치의 V30/V31(post/comment 테이블)이 이미 적용되어 있어 정책 관련 마이그레이션을 V32/V33으로 재넘버링했다(V30__create_policy_document.sql 커밋 포함). Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01JNjhau1bE58LegkwKtPBq2
이슈 #118: User.agreedTerms/agreedPrivacy/agreedAt 필드를 제거하고, 회원가입 완료 시 현재 시행 중인 TERMS/PRIVACY PolicyDocument에 대한 UserPolicyAgreement를 기록하도록 AuthService.register()를 리팩터링한다. 이미 동의 이력이 있으면 건너뛰어 탈퇴 후 재가입 시 유니크 제약 위반을 방지한다. 레거시 컬럼은 V34 마이그레이션으로 제거한다.

이슈 #118: 정책 변경 이메일 발송 대상과 발송 상태(PENDING/SENT/FAILED), 재시도 횟수를 추적하는 PolicyNotificationTarget을 추가한다. 배치 Job이 이 테이블을 기준으로 대상 생성과 발송 상태 갱신을 수행한다(후속 커밋). Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01JNjhau1bE58LegkwKtPBq2
이슈 #118: Gmail SMTP 기반 JavaMailSender 설정과 Thymeleaf 이메일 템플릿(policy-change-notice.html)을 추가한다. 법적 고지 목적상 수신거부 링크는 넣지 않고, 발신자 정보·변경사항 요약(changeSummary)· 시행일자를 본문에 필수로 노출한다. requiresReconsent인 경우 재동의 필요 안내를 추가로 표시한다.

이슈 #118: Spring Batch를 도입하고, 정책 발행 시 ACTIVE 유저 중 이메일이 있고 아직 대상이 아닌 유저를 PENDING 상태의 PolicyNotificationTarget으로 등록하는 Tasklet을 추가한다. 배치 스키마는 Flyway(V36)로 관리하고, spring.batch.job.enabled=false로 앱 기동 시 자동 실행되지 않도록 한다(트리거는 후속 커밋). Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01JNjhau1bE58LegkwKtPBq2
이슈 #118: PENDING 상태 PolicyNotificationTarget을 청크 단위로 읽어 메일을 발송하고 상태(SENT/FAILED)를 갱신하는 Step2를 추가하고, Step1(대상 생성)과 Step2(메일 발송)를 policyNotificationJob으로 조립한다. 발송 실패(SMTP 예외 포함)는 FAILED로 마킹되어 재시도 대상이 된다(재시도 스케줄러는 후속 커밋). 임시 DB에 V1~V36 전체 마이그레이션을 적용해 실제 앱을 기동, Job/Step/ Reader/Processor/Writer 빈 그래프가 정상 등록되는지 확인했다.

이슈 #118: 정책 등록 트랜잭션 커밋 후(@TransactionalEventListener AFTER_COMMIT) policyNotificationJob을 동기로 실행하는 트리거를 추가한다. 발송 실패(FAILED) 대상은 별도 스케줄러가 1시간 간격으로 최대 3회까지 재시도한다. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01JNjhau1bE58LegkwKtPBq2
임시 DB에 실제 앱을 기동해 관리자 API로 정책 등록 → 배치 실행까지 end-to-end로 검증한 결과 두 가지 실행 시점 버그를 발견해 수정했다. - JobOperator.start(Job, JobParameters)는 인크리멘터가 설정된 Job에서 run.id 외의 커스텀 파라미터(policyId)를 무시하고 버림 → run(...)으로 전환 - @TransactionalEventListener(AFTER_COMMIT) 콜백과 같은 스레드에서 자체 트랜잭션을 가진 배치를 실행하면 트랜잭션 동기화 상태 충돌로 JobInterruptedException 발생 → 별도 스레드에서 실행 후 join으로 대기 수정 후 Step1(대상 생성) → Step2(메일 발송, 실패 시 FAILED 처리) → Job COMPLETED까지 실제 동작을 확인했다.

Inline comments:
In `@src/main/java/com/Coming/Backend/auth/repository/UserRepository.java`:
- Line 19: Change UserRepository.findByStatus to use paginated or keyset-based
retrieval instead of returning all users at once, then update the policy target
creation flow that calls it to process and persist users in bounded batches
while preserving active-user filtering.
In `@src/main/java/com/Coming/Backend/auth/service/AuthService.java`:
- Around line 162-170: Make user policy agreement creation atomic in the service
flow around existsByUserIdAndPolicyId and UserPolicyAgreement.builder().save by
replacing the separate existence check and insert with a PostgreSQL upsert or
conflict-ignoring insert keyed by (userId, policyId). Preserve the unique
constraint and add a concurrent signup test verifying simultaneous requests do
not fail with a uniqueness exception.
In
`@src/main/java/com/Coming/Backend/policy/batch/PolicyNotificationBatchConfig.java`:
- Around line 71-74: Update mailSendItemReader and its findByPolicyIdAndStatus
paging flow to use a keyset or cursor-based reader instead of offset pagination,
while retaining ascending id ordering and PENDING filtering. Ensure status
mutations persisted by sendAndMark do not cause later chunks to skip targets,
and add a multi-chunk test verifying every target is processed.
- Around line 50-61: Refactor the mailSendStep flow so
PolicyNotificationMailProcessor and PolicyNotificationTargetWriter do not send
SMTP messages within the chunk transaction: reserve targets in a short database
transaction, perform PolicyNoticeMailSender.send outside it, then persist SENT
or FAILED in separate transactions. Add recovery or idempotency handling for
reservations left in progress so job restarts cannot resend already accepted
messages.
In
`@src/main/java/com/Coming/Backend/policy/batch/PolicyNotificationJobTrigger.java`:
- Line 32: Update PolicyNotificationJobTrigger’s transactional event handling to
dispatch runJob through the configured Spring async executor after the existing
AFTER_COMMIT phase, returning immediately to the policy-registration caller.
Remove the manual virtual-thread creation and jobThread.join() wait while
preserving the existing job behavior.
- Around line 34-43: Make notification launch durable by creating a persistent
outbox/launch record within the same transaction as
PolicyService.registerPolicy, then have PolicyNotificationJobTrigger process and
retry pending records through JobOperator until
PolicyNotificationTargetCreationTasklet completes successfully. Do not rely on
the AFTER_COMMIT runJob invocation or logging alone; ensure failed launches
remain discoverable and are retried by a durable worker.
In
`@src/main/java/com/Coming/Backend/policy/batch/PolicyNotificationRetryScheduler.java`:
- Line 33: Remove the class-level transaction from the retry scheduler and
separate SMTP sending from database transactions. Update the flow around
policyNotificationSender.sendAndMark() to reserve recipients in a short
transaction, perform external mail delivery outside it, then persist each
delivery result in an independent transaction using appropriate propagation so
failures cannot roll back recipient reservations or previously recorded results.
In
`@src/main/java/com/Coming/Backend/policy/batch/PolicyNotificationTargetCreationTasklet.java`:
- Around line 39-49: The PolicyNotificationTargetCreationTasklet must filter
users by UserPolicyAgreementRepository only when the policy’s requiresReconsent
value is true; preserve notification of all eligible active users when it is
false. Load the policy and use its requiresReconsent setting before creating
PENDING targets, excluding users with an existing agreement only in the
re-consent branch, and add tests covering both branches.
In
`@src/main/java/com/Coming/Backend/policy/entity/PolicyNotificationTarget.java`:
- Line 54: Update PolicyNotificationTarget.markFailed and the
PolicyNotificationRetryScheduler retry eligibility logic so an initial delivery
failure does not consume one of the three allowed retries. Distinguish the
initial attempt from retry attempts, or adjust the counter semantics and
threshold consistently, while preserving a maximum of three retry deliveries.
In `@src/main/resources/application.yaml`:
- Line 74: Update the mail STARTTLS configuration by adding the required setting
alongside the existing starttls.enable option, ensuring SMTP authentication
cannot proceed without TLS.
- Line 69: Configure finite SMTP connection and response timeouts under the
existing mail properties, adding connectiontimeout and timeout alongside
smtp.auth and preserving the current STARTTLS settings; use values appropriate
for the operational requirements.

Separate initial SMTP delivery from the chunk transaction.
PolicyService.register publishes PolicyRegisteredEvent, and PolicyNotificationJobTrigger starts policyNotificationJob after commit. In mailSendStep, PolicyNotificationMailProcessor calls PolicyNotificationSender.sendAndMark inside the configured chunk transaction. That method invokes PolicyNoticeMailSender.send, then marks the target SENT; PolicyNotificationTargetWriter persists the chunk.
If a later processor call, saveAll, or transaction commit fails, the chunk rolls back. The SMTP server can already have accepted the earlier messages, while their targets remain PENDING. A job restart can select those targets again and send duplicate messages.
Reserve targets in a short database transaction, send mail outside that transaction, and record SENT or FAILED in a separate transaction. Add recovery or idempotency handling for reservations that remain in progress.

Use a keyset or cursor reader for status-mutating chunks. mailSendItemReader pages findByPolicyIdAndStatus(..., PENDING, pageable) with an offset and pageSize(20). sendAndMark changes each processed target to SENT or FAILED, and the writer persists those changes. The next page therefore applies offset 20 after those rows leave the PENDING result set. With 40 targets, the second page can be empty and targets 21–40 remain PENDING. Add a multi-chunk test that asserts every target is processed.

Do not wait for batch completion in the event listener.
Line 32 blocks the policy-registration caller until target creation and all email sends complete. A large recipient set or slow SMTP server can keep the registration operation blocked long enough to time out.
Keep @TransactionalEventListener(phase = AFTER_COMMIT), but dispatch runJob through a configured Spring async executor. Remove the manual virtual thread and join().

이 트랜잭션은 대상 순회 전체와 policyNotificationSender.sendAndMark()의 SMTP 호출을 포함합니다. 메일 발송 후 이후 대상 처리 또는 커밋이 실패하면 데이터베이스 상태는 롤백되지만 이미 전송된 메일은 취소되지 않습니다. 대상은 다시 FAILED로 남고 다음 실행에서 중복 메일을 발송합니다. 짧은 트랜잭션으로 발송 대상을 예약하고 발송 결과를 별도 트랜잭션으로 기록하십시오. Spring의 기본 전파는 같은 물리 트랜잭션에 참여하며, 롤백 표시는 외부 트랜잭션의 커밋에도 영향을 줍니다. (docs.spring.io)
Based on learnings: Do not include a non-transactional external API call with local database changes in one database transaction.

at line 33, Remove the class-level transaction from the retry scheduler and
separate SMTP sending from database transactions. Update the flow around
policyNotificationSender.sendAndMark() to reserve recipients in a short
transaction, perform external mail delivery outside it, then persist each
delivery result in an independent transaction using appropriate propagation so
failures cannot roll back recipient reservations or previously recorded results.

Filter targets only when requiresReconsent is true. PolicyService.registerPolicy stores requiresReconsent, but the tasklet does not load the policy or check UserPolicyAgreementRepository. A re-consent policy can therefore create a PENDING target for an active user who already agreed and send that user a re-consent email. A policy with requiresReconsent=false must still notify all active users. Apply the agreement filter only in the re-consent branch, and add tests for both branches.

변경 개요
커뮤니티 기능 추가로 이용약관·개인정보처리방침 개정이 필요해짐에 따라, 정책 변경 사항을 사용자에게 이메일로 고지하는 시스템을 추가한다. 프론트엔드가 약관 원문을 SSOT로 관리하므로 백엔드는 원문을 저장하지 않고 버전 메타데이터·동의 이력·발송 상태만 관리한다.

registerPolicy) 트랜잭션이 커밋된 후에만 배치가 실행되도록@TransactionalEventListener(phase = AFTER_COMMIT)를 사용했다. 커밋 중인 트랜잭션과 같은 스레드에서 배치(자체 트랜잭션 포함)를 직접 실행하면 트랜잭션 동기화 상태가 충돌해JobInterruptedException이 발생하므로, 별도 가상 스레드에서 실행하고join()으로 대기한다.PolicyNotificationSender)을 배치 Step2 Processor와 재시도 스케줄러가 공통으로 사용하도록 분리해 중복을 제거했다.agreedTerms/agreedPrivacy이력은 현재 시행 중인 정책(effectiveDate <= 오늘중 최신)에 대해 기록하며, 탈퇴 후 재가입 케이스를 고려해 이미 동의 이력이 있으면 건너뛴다.테스트
./gradlew test통과)리뷰어 참고사항
AuthService.recordPolicyAgreement는 시행 중인 TERMS/PRIVACY 정책이 하나도 없으면PolicyNotFoundException을 던진다. 배포 후 신규 가입을 받으려면 admin API로 초기 정책 버전을 반드시 먼저 등록해야 한다.PolicyNotificationJobTrigger는 배치(대상 생성 + 전체 메일 발송)가 끝날 때까지 커밋 후 콜백 스레드에서 동기적으로 대기한다. 현재 유저 규모에서는 문제가 없지만, 대상자가 많아지면 정책 등록 API 응답 지연으로 이어질 수 있다.코드 리뷰
변경사항 요약
정책 버전 등록 API, 회원가입 시 약관 동의 이력 기록, Spring Batch 기반 알림 대상 생성·메일 발송·실패 재시도까지 이어지는 정책 변경 고지 파이프라인 전체를 추가했다.
검토 결과
🟡 warning
PolicyNotificationJobTrigger: 정책 등록 API 요청이 배치 Job(대상 생성 + 전체 대상 메일 발송) 완료까지 동기적으로 블로킹된다.→ 유저 수가 늘어나면 admin API 응답 시간이 함께 늘어난다. Job 트리거를 fire-and-forget으로 바꾸고 별도 상태 조회 API를 제공하는 방향을 검토할 수 있다.
PolicyNotificationTargetCreationTasklet:userRepository.findByStatus(ACTIVE)로 활성 유저 전체를 한 번에 메모리에 로드한다.→ 유저 규모가 커지면 페이징 처리가 필요하다.
🔵 suggestion
