MemberRepository입니다

    }

    public Member find(Long id) {
        return em.find(Member.class, id);
    }
}

application.yml입니다!

그리고 질문란에 써있는데로, H2를 실행한 상태이고, jpashop.mv.db도 만들어져 있습니다. 또 혹시 제가 코드를 잘못 작성했을까봐 강의자료에 나와있는 자료들을 모두 복붙하였습니다. gradle까지 복붙했습니다.. 그런데 자꾸 오류가 생성되어 여쭤보게 되었습니다. 감사합니다! 추가로 컴퓨터도 껐다 켜봤습니다!

또 추가적으로, 그 영한님이 주신 강의 소스코드로 전체 완성본은 또 돌아가더라고요.. 그래서 더더욱 뭐가 문제인지를 모르겠습니다 ㅠㅠ
