[질문 내용]
영한님께서는 @GeneratedValue의 속성값을 auto로 설정해서 h2 데이터베이스에 맞는 기본키전략, 즉 시퀀스 전략을 사용했습니다. 하지만 저는 Identity 전략으로 사용이 되는데 무슨 이유일까요? auto로 해도 Identity 전략, @GeneratedValue의 속성값을 시퀀스로 설정해도 Identity전략으로 됩니다.

이런식으로 실행된 로그를 보면 sequence가 나오는데 실제 h2.db에는 그대로 identity 전략이 사용되네요 ㅠㅠ

안녕하세요. hal8hal9님, 공식 서포터즈 OMG입니다.
.
Member 엔티티를 현재 코드로 둔 채,
jpashop DB를 완전히 지우고(jpashop.mv.db를 삭제해주세요),
application.yml에서 ddl-auto를 create로 한 후
다시 생성해서 확인해보시겠어요?
.
감사합니다.

왜 IDENTITY 전략이 실행된다고 생각하시는건지 알 수 있을까요?
제 생각에는 SEQUENCE가 제대로 동작한다고 생각이 되어서요
