메서드 계약과 구현 간의 불일치 확인 필요
Line 71의 주석은
aiChatImageId가 null이 아니면 해당 이미지가 반드시 존재해야 한다고 명시하고 있습니다. 하지만 Lines 80-82의 구현은.orElse(List.of())를 사용하여 이미지가 없을 경우 조용히 빈 리스트를 반환합니다.이는 다음과 같은 문제를 야기할 수 있습니다:
AiChatMessageService에서 이미지 존재 여부를 검증(Line 65)한 후, 비동기 메서드가 실행되기 전에 이미지가 삭제되면 조용히 무시됨다음 중 하나를 선택하여 일관성을 확보하세요:
옵션 1 (권장): 이미지가 없으면 예외 발생
// 이미지가 있으면 해당 이미지 조회 List<AiChatImageEntity> aiChatImages = List.of(); if (aiChatImageId != null) { - aiChatImages = aiChatImageRepository.findById(aiChatImageId) - .map(List::of) - .orElse(List.of()); + AiChatImageEntity aiChatImage = aiChatImageRepository.findById(aiChatImageId) + .orElseThrow(() -> new AppException(ErrorCode.IMAGE_NOT_FOUND_EXCEPTION)); + aiChatImages = List.of(aiChatImage); }옵션 2: 주석을 구현에 맞게 수정
