오류는 이부분이고 H2버전을 낮추라고 해서 버전을 낮췄는데도 같은 오류가 나서 Order 부분이 문제인거 같습니다.

[ Member. class ]

@Entity
public class Member {

    @Id @GeneratedValue
    @Column(name = "MEMBER_ID")
    private Long id;

    @Column(name="USERNAME")
    private String username;

    @OneToMany(mappedBy = "member")
    private List<Order> orders = new ArrayList<>();

}

 

[ Order.class ]

@Entity
public class Order {

    @Id @GeneratedValue
    private Long id;

    @ManyToOne
    @JoinColumn(name = "MEMBER_ID")
    private Member member;

    @ManyToOne
    @JoinColumn(name = "PRODUCT_ID")
    private Product product;

    private int count;
    private int price;

}

참고한 자료를 모두 시도했으나 같은 오류가 발생해서 문의드립니다.

https://github.com/MrPPak/ex1-hello-jpa

여기있는 코드대로 했고 문제의 코드는 Member, Order, Product부분입니다.

한번 확인해주시면 정말 감사하겠습니다.

Order가 H2에서는 예약어로 잡혀있네요.

강의 내에서 작성된 것처럼 Order 대신 MemberProduct으로 이름을 변경하여 진행해주세요.

안녕하세요. fecorp님, 공식 서포터즈 David입니다.

.
h2에 접속하셔서 기존에 생성된 테이블을 모두 제거한 뒤 다시 시도해보시겠어요?

그래도 안 되신다면 아래 글을 참고하셔서 Hibernate 버전을 올려서 프로젝트에 적용하신 뒤 다시 시도해주세요.

감사합니다.
