(질문 잘하기 메뉴얼 링크: https://bit.ly/2UfeqCG) 질문 시에는 위 내용은 삭제하고 다음 내용을 남겨주세요. ========================================= [질문 템플릿] 1. 강의 내용과 관련된 질문인가요? (예/아니오) 2. 인프런의 질문 게시판과 자주 하는 질문에 없는 내용인가요? (예/아니오) 3. 질문 잘하기 메뉴얼을 읽어보셨나요? (예/아니오) 혹시나 잘못 타이핑한 거 있나 싶어서 지난 강의 내용들 pdf로 전부 복붙해서 갈아엎고 그래도 계속 에러가 터져서 여러가지 경우로 실험을 해봤는데 @Configuration만 붙으면 에러가 터집니다.. 어떻게 해야 할까요? ㅜㅜ 참고로 일부러 보기 편하시라고 코드 텅 비워놓은 것이고 강사님 pdf 파일에 있는 코드 그대로 갖다 붙여도 똑같습니다. 그리고 해당 테스트 말고 다른 테스트도 Configuration 붙이면 터집니다.. 에러 코드로 검색해봐도 구글링해도 별다른 게 없어서 괴롭네요 Spring boot 2.7.1버전 JAVA 11 버전입니다.. /Library/Java/JavaVirtualMachines/jdk-11.0.15.1.jdk/Contents/Home/bin/java

우선 테스트 실패는 ApplicationContextSameBeanFindTest에서 실패하는데요, Map~ 아래에 { } 로 코드가 한번 더 중괄호로 묶여 있는 부분이 강의와 다르네요. 코드 일부만으로 확인이 어려워 우선 첨부하신 이미지 정보를 바탕으로 단서를 찾고 있는데, 이 문제가 아니라면 코드 확인이 필요할 것 같습니다. 수정 후 결과를 공유해주세요.

안녕하세요. 으뀨뜌 님, 공식 서포터즈 OMG입니다. 강의와 다르게 작성한 부분이 보이네요. ApplicationContextExtendsFindTest 위의 @Configuration을 지워주세요. 추가로, AppConfig의 위치를 order 패키지 바깥으로 위치해주세요. 해결이 안될 경우 댓글남겨주세요. 감사합니다.
