안녕하세요 기선님.

강의 잘 듣고 있습니다 ~ 좋은 강의 제공해주셔서 감사드려요 ! 

다름이아니라 실습중에 에러가 생겨서요ㅜㅜ 구글링을 해보고 했는데, 다른 부분들을 잘 이해하지 못해 해결이 잘 안되더라고요.. 그래서 이렇게 질문 남깁니다 ! 소스코드는 아래 공유드립니다 !

https://github.com/g1moon/study/tree/master/Web-Programming/%5Binflearn%5D-Spring-Boot/springbootjpa

우선 account를 엔티티 등록할 때 

@Entity ->이부분 org.hibernate.annotations.Entity' is deprecated 
public class Account {
    @Id @GeneratedValue
    private Long id;

------------------------------
엔티티 어노테이션이 디프리케이트되더라고요... 다른 거로 임포트하면 하이버네이트 어노테이션을
이용하라고 하는 것 같고요 .. 이러한 상태에서 빈 테스트를 돌렸을 떄 잘 돌아기간하는데,
dataSoruce부분에서 문제가 생깁니다..

SpringbootApplicationTest.java를 해보면
