스프링 인터셉터 호출에서 afterCompletion에서 질문이 있습니다.

아하! 감사합니다ㅎㅎ

여러가지 오류를 만나다, 해결을 하였지만 소스 중에서 이해가 되지 않는 부분이 있어 작성하게 되었습니다.

1. .gradle이 복잡 (사진) 2. .gradle 저장 경로 잘못 지정 (사진) 제가 첫 프로젝트 settings 할 때 저장 경로가 잘못 지정하여 hello-springs에 .gradle 디렉터리 및 파일들이 다 저장된 것 같습니다. 결론 선생님, 완성된 프로젝트 참고해서 수정해보겠습니다! 선생님 마지막 질문으로, 현재 스프링 입문 수업을 들으며 배웠던 스프링 DB 접근 및 AOP를 새로운 프로젝트에다가 구현하기는 힘들거 같습니다. (소스를 보면 '수업시간에 배운 게 이거구나' 정도는 가능할 것 같습니다.) 혹시 이후 강의에서(스프링 핵심 원리 - 기본편, 스프링 MVC 1편 등) 다시한번 깊게 스프링 DB 및 AOP를 배우게 되는걸까요??

OMG 선생님, 안녕하세요. 알려주신 내용 적어놓겠습니다ㅎㅎ 제가 이해 못한 부분은, 1. member1, member2 입력 값이 다를 경우 (사진) member1에 spring123e2 입력 member2에 pring123vc2 입력 이와 같이 다를경우 org.opentest4j.AssertionFailedError: Expected
