📝작업 내용

기존코드
case "participant_left" -> {
Room room = roomRepository.findByTitle(roomName);
if (room != null) {
room.setParticipantCount(room.getParticipantCount() - 1);
roomRepository.save(room);
}
if (room != null && room.getParticipantCount() > 0) {
if (room != null && roomParticipantCount > 0) {
room.setParticipantCount(roomParticipantCount);
roomRepository.save(room);
System.out.println("Participant left. Current count: " + room.getParticipantCount());
log.info("Participant left now. Current count: {}", roomParticipantCount);
}
else if (room != null && room.getParticipantCount() == 0) {
else if (room != null && roomParticipantCount == 0) {
roomRepository.delete(room);
System.out.println("Room deleted: " + roomName);
log.info("Room deleted: {}", roomName);
}
}

불필요한 if 절을 제거하고 데이터베이스에서 방의 인원을 직접 수정하던 코드를

수정코드
int roomParticipantCount = event.getRoom().getNumParticipants();

                case "participant_left" -> {
                    Room room = roomRepository.findByTitle(roomName);
                    if (room != null && roomParticipantCount > 0) {
                        room.setParticipantCount(roomParticipantCount);
                        roomRepository.save(room);
                        log.info("Participant left now. Current count: {}", roomParticipantCount);
                        }
                    else if (room != null && roomParticipantCount == 0) {
                        roomRepository.delete(room);
                        log.info("Room deleted: {}", roomName);
                    }
                }

웹훅을 수신하여 이벤트를 통해 받아온 방의 인원수를 데이터베이스에 담는 방식으로 수정하였습니다.
