문제 원인

PICNIC(현장체험학습)으로 상태 변경 후 매일 21:00에 실행되는 리셋 스케줄러가 동작하지 않는 버그 두 가지가 겹쳐 있었습니다.

---

Bug 1: ResetStatusService — @Transactional(readOnly = true) 로 인한 리셋 불가

// 수정 전
@Transactional(readOnly = true)
override fun reset() {
    // ...
    saveStatusPort.saveAll(update)  // readOnly = true → flush 안 됨 → DB 미반영
}

// 수정 후
@Transactional
override fun reset() {

readOnly = true로 설정 시 JPA의 FlushMode가 MANUAL로 강제되어 saveAll() 호출이 있어도 실제 DB에 커밋되지 않았습니다. PICNIC뿐 아니라 모든 상태 리셋이 동작하지 않는 근본 원인이었습니다.

Bug 2: ResetAttendanceService — PICNIC 출석 상태를 영구 보존 처리

// 수정 전
when (currentStatus) {
    AttendanceStatus.DROPOUT, AttendanceStatus.PICNIC, AttendanceStatus.EMPLOYMENT -> currentStatus
    else -> AttendanceStatus.ATTENDANCE
}

// 수정 후
when (currentStatus) {
    AttendanceStatus.DROPOUT, AttendanceStatus.EMPLOYMENT -> currentStatus
    else -> AttendanceStatus.ATTENDANCE
}

퇴학(DROPOUT)·취업(EMPLOYMENT)은 영속성 유지가 맞지만, 현장체험학습(PICNIC)은 하루짜리 상태이므로 다음날 ATTENDANCE로 돌아와야 합니다.

---

영향 범위

• ScheduleService.resetTable() (매일 21:00 실행) 내 resetStatusUseCase.reset() + resetAttendanceUseCase.resetAttendance() 정상화
• PICNIC 상태 학생이 다음날 자동으로 ATTENDANCE로 복구됨

Test plan

• PICNIC으로 상태 변경 후 reset() 호출 시 Status가 ATTENDANCE로 변경되는지 확인
• PICNIC 상태의 출석(period6~10)이 리셋 후 ATTENDANCE로 돌아오는지 확인
• DROPOUT, EMPLOYMENT 상태는 리셋 후에도 유지되는지 확인
