안녕하세요 강사님.
테스트가 진행하다가 멈춰버리네요.
강사님 강의에는 전파전략이 있고 깃헙에는 또 없으신데... 어느게 맞는건가 싶기도 합니다...

제 깃헙에 저장된 소스입니다.

mj Song 님 안녕하세요
깃헙에 올려주신 소스를 확인해봤는데
@Transactional(propagation = Propagation.REQUEST_NEW) 옵션을 facade 에 붙여주셨더라고요..!
facade 에 있는 @Transactional 을 StockService 로 옮기시고 StockService 에 붙어있는 Synchronized 를 삭제하시면 되실겁니다.
이렇게해도 안되시면 다시한번 답글 달아주세요!!

로그를 확인하니 재고가 32개까지만 딱 줄고 그 뒤로는 멈추는거 같습니다
마지막 락 제거하고가 딱 끝이네요

mj Song 님 안녕하세요.
어느부분을 수행하다가 멈추시는지 알려주실 수 있으실까요 ?
전파전략이 있는건 named lock 부분이 맞을까요 ?
맞다면 전파전략이 있는것이 맞습니다.
깃헙에는 최종본 소스가 올라가있기때문에 상이한것 같습니다.
감사합니다.
