영한님 안녕하세요! 어제 답변주시거 해결하고 다음강의 듣는 중에 또 문제가 생겼습니다 ㅠ_ㅠ
1. 터미널에서 ./h2.sh 명령어로 실행
2. localhost:8082로 접속
3. member 테이블생성
4. 강의를 따라가면서 아래 코드만 작성 후 실행했는데,
EntityManagerFactory emf = Persistence.createEntityManagerFactory("hello");
EntityManager em = emf.createEntityManager();
Member member = new Member();
em.persist(member);
em.close();
emf.close();
강의처럼
ids for this class must be manullay~ 이 에러가 아닌 아래와 같은 에러가 나타납니다 ㅠㅠ 뭐가 문제일까요??
