강사님 도와주세요 ㅠㅜ 스프링데이터 JPA 오류

Question

강사님....

스프링 데이터 JPA 편 듣고있는데

진짜 있는그대로 얼마안되는 코드 토씨하나 안틀리고 썼는데....심각한 오류가 발생했는데

도저히못찾겠어요 뭐가 문제인건지 모르겠습니다....

그전강의 JPA 강의보면서 로직짜볼떈 아무이상없었는데

스프링 데이터 JPA를 쓰려고 필요없는거 삭제하고 인터페이스만들고 나온내용대로 따라했더니 치명적인오류가

나오는데.....이게 어디서부터 뭐가잘못되었는지 아무리찾아봐도 알 수가 없어요ㅠㅜ

혹시몰라서 제가 오류난 부분을 Console 창 복사해서

여기에 남깁니다......
