안녕하세요 강사님

요렇게 나오고

기존에 만들었던 멤버클래스랑 멤버리파지토리클래스를 지워서 테스트에 MemberRepositoryTest에 빨간줄 그어진거랑은 상관없이 테이블이 만들어지지않는거같은데

어디서 에러가나는건지 잘모르겠어요 ..ㅜ

Member의 다음 부분을 확인해주세요.

@Embedded
private Address address;

Address 부분도 확인해주세요.

package jpabook.jpashop.domain;

import lombok.Getter;

import javax.persistence.Embeddable;

@Embeddable
@Getter
public class Address {

    private String city;
    private String street;
    private String zipcode;

    protected Address() {
    }

    public Address(String city, String street, String zipcode) {
        this.city = city;
        this.street = street;
        this.zipcode = zipcode;
    }
}
