@Repository
@RequiredArgsConstructor
public class MemberRepository {
private final(추가) EntityManager em;
코드 확인해보았습니다.
final 키워드를 추가해야 생성자 주입이 발생합니다. final을 추가해주세요
@RequiredArgsConstructor에 대해 아시면 좋을 것 같네요.

확인해보았는데 객체를 생성하고 메서드를 호출했습니다. 강의랑 똑같이 코드를 작성했습니다. 위에 첨부한 사진처럼 join메서드를 호출할때 빨간 밑줄표시가 뜹니다!

안녕하세요.
프로젝트 코드를 확인해봐야 할 것같아요.
전체 프로젝트를 압축해서 구글 드라이브로 공유해서 링크를 남겨주세요.
구글 드라이브 업로드 방법은 다음을 참고해주세요.

주의: 업로드시 권한 문제 꼭 확인해주세요
감사합니다
