참고)
Member 클래스에
@Override
public String toString() {
return "Member [id=" + id + ", name=" + name + " ]";
}
추가하고 커밋한 뒤에
Member retrievedMember = em.find(Member.class, 1L);
System.out.println("Retrieved Member: " + retrievedMember);
조회해봤을때
Retrieved Member: Member [id=1, name=mini ]
이렇게 잘 나오네요. 무가 문제일까요...?
