빌더패턴질문

createmember라는메서드를 만들어서 사용하려는데 메서드안에서는 빌더를못쓰는걸까요?
public static Member createMember(){
이안에 빌더가안써져서요 ㅠㅠ
}
&nbsp;

안녕하세요 기본편을수강했는데 제가 그래들만쓰다가 이 편에서는 (실전1편에서는 그래들) 메이븐을쓰시던데&nbsp;
저는 그냥그래들로 하고들어도상관없을까요?&nbsp;

merge관련

감사합니다 더 공부해보겠습니다

order builder패턴 질문

그럼 위에 같은 경우는&nbsp;
 Order order = Order.builder()
 .member(member)
 .delivery(delivery)
 .orderItems(new OrderItem[] {orderItems)
 .build();
이게 맞나요? 빨간줄이 뜨는데&nbsp;

오...이해했씁니다 감사합니다

cascade관련

아이디만 지우고하시라는말씀이실까요 ?
