query method 질문합니다!Member findMember = memberRepository.findByNameAndAgeGreaterThan("kim",20);에서findByNameAndAgeGreaterThan 이라는 부분이 어떻게 구현 되어 있는지 볼 수 있을까요?어느 파일을 타고 들어가야 볼 수 있는지 궁금합니다! 

안녕하세요. 타임리프 렌더링 관련해서 질문이 있습니다.현재 스프링부트랑 타임리프 버전이 3.3.2입니다.html에서 사용하면 아래와 같이 렌더링이 안되어 있는 거 같습니다.버전에 문제일까요?

기선님 강의를 여러개 들었는데 이전에 라이브러리를 직접 만들고 시연해줬던 강의를 찾고 있는데 어디있는지 모르겠습니다. ㅠㅠ 혹시 어떤 강의인지 알려주실 수 있으실까요?

to one 관계는 여러개를 사용해도 상관없고 to many 관계는 한개만 사용해야 된다고 하셨는데 질문이 생겨서 글을 써봅니당 테이블 A가 있다고 할때, A테이블이 B,C,D 테이블과는 to one 관계이고 E 테이블과는 to many 관계인 경우에 A 테이블에서 B,C,D,E 테이블을 전부 fetch join해도 문제가 없는건가요? ( B,C,D,E 테이블은 A에만 연관관계가 있고 B,C,D,E 끼리의 관계는 존재하지 않습니다.) 여러개의 테이블을 join하는 경우 to many관계가 한개 , 나머지 테이블은 to one관계이면 모두 fetch join해도 되는건지 알고싶습니다.

안녕하세요 토비님 혹시 강의자료로 사용했던 notion 은 공유 안되나요?

첫번째 스크린샷 build ~ using을 인텔리제이로 썼을 땐 에러가 안 나는데 이번 강의에서 gradle(default)로 설정한 후 main함수 실행 시 에러가 뜨며 실행이 되지 않습니다. 다른 질문들 참고해봤는데 다른 건 없고 계속 똑같은 오류가 뜨더라구요.. 해결 방법이 있을까요?
