다대다 관계 풀어내는 과정에서 질문이 있습니다!

안녕하세요. 항상 좋은 답변 주셔서 감사합니다.

이번에 강의를 듣고 복습하는 과정에서 잘 안되는 부분이 있어 여쭤보고 싶어 글을 적습니다.

이미지는 위를 참고 부탁드리며, MemberProduct 중간 Entity를 DB의 ORDER TABLE과 연결해서 쓰려고 합니다. 

@Entity
@Table(name = "order")
public class MemberProduct {

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

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

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

    private int orderAmount;
    private LocalDate orderDate;

}

코드는 위와 같이 작성했습니다. 코드를 실행하면 create Table Order까지는 나가는 것이 확인이 되는데, 아래와 같은 warning이 발생되는 것을 확인했습니다. 그리고 실제 H2 DB에는 생성이 되지 않았습니다. Warning 메세지는 아래와 같습니다.

혹시 어떤 것이 문제점이 되는지 알려주실 수 있으실까요? 감사합니다!
