인프런 커뮤니티 질문&답변

우선은 무시하고 그냥 동이랗게 진행하시고, 나중에 찾아서 해보시길 바랍니다.

그거 하다 보면 엄청많은 문제에 직면하면서 본래 강의를 못들을겁니다... 저는 전에 하다가 죽을뻔햇습니다...

정 궁금하시면 여기 사이트 참고하시면 됩니다.

저는 많은 시행착오와 위의 사이트 참고, 그리고 다른 spring security 강의를 들어서 다음과같이 수정이 가능햇습니다.!

기본적으로 deprecated 된 방식 말고 새로운 방식은 bean을 중점적으로 등록하는 방식으로 진행됩니다. 그렇기 때문에 어떤 bean을 수정해야 하는지 spring security 를 좀 아셔야합니다.
