인프런 커뮤니티 질문&답변

메서드 추출은 되는데

IntelliJ IDEA 2023.2.2 Ultimate
(컴퓨터는 맥북)

해당 버전 사용중입니다

중복된 메서드일때 intellij 에서

Extract Parameters to Replace Duplicate
(10:34 초부분)

이건 안되네요.

인텔리제이 버전 업하면서 그런거같은데

혹시 해당 화면처럼 하는 팁 있을까요?

전체코드고

아래 부분을 메서드 추출하면 중복 체크하고 매개변수 넘기는 방식으로는 안되네요..

 Member member = new Member();
            member.setName("userA");
            member.setAddress(new Address("서울", "1", "1111"));
            em.persist(member);
