@Test void 회원가입() { //given Member member = new Member(); member.setName("hello"); //when Long saveId = memberService.join(member); //then ( 우리가 save한게 repository에 있는 것이랑 같아?를 찾는 로직) Member findMember = memberService.findOne(saveId).get(); assertThat(member.getName()).isEqualTo(findMember.getName()); //Assertions.assertThat(member.getName()).isEqualTo(findMember.getName()); } 위 회원가입 테스트 코드에서 처음에는 static으로 import 안해서(1) >>>>Assertions.assertThat(member.getName()).isEqualTo(findMember.getName());이렇게썼다가다시 import static org.assertj.core.api.Assertions.*;하면서 아래 로직으로 바꾸는 이유가 궁금합니다.(2) >>>>assertThat(member.getName()).isEqualTo(findMember.getName());굳이 바꾸는 이유가 무엇인지 궁금합니다.오로지 가독성때문에 그러는것인가요?그렇다면 처음부터 import static~으로는 import가 불가능한것인지도 궁금합니다!(1)처럼 쓴다음에 (2)로 다시 바꾸면서 import를 static으로 변경하는 방법만 있는지 궁금해서요.

(예)[질문 내용]강의를 보고 엔티티를 설계하여 프로젝트를 진행하고 있습니다. 강의에서 말씀해주신대로 모든 FetchType을 LAZY로 하여 개발하고 있는데 문득 지연로딩이 실제로 어떤 상황에 필요한지가 궁금해졌습니다.강의에서 말씀해주신대로 연관관계 매핑 데이터를 즉시 가져오지 않고 필요할 때 사용할 수 있도록 할 때 지연로딩을 사용한다는 것은 이해했습니다.실무에서 어떤 상황에 적용되는지 찾아보니, 여러 이미지들을 스크롤하면서 이미지를 실제로 화면에서 보게 될 때 사용하면 효율적이라는 포스팅을 보았습니다.그런데 또 실무에서는 OSIV를 off한다고 보았습니다. OSIV가 off라면 영속성 컨텍스트가 Service, Repository에서만 살아있게 되어 어쨌든 Service 단에서 모두 처리해야 하는데 그렇다면 지연로딩이나 즉시로딩이나 별 차이가 없는 것 아닌가요?? 혹시 제가 잘못 알고 있는 것이 있는지, 어떤 상황에서 지연로딩을 사용하는 것이 좋은지 궁금합니다. 감사합니다:)

(예/아니오)[질문 내용]안녕하세요. 강사님의 강의를 쭉 따라들으며 진행하던 중, 데이터베이스까지 연동을 하여 localhost:8080에 회원 목록이 뜨는 것을 확인했습니다.근데 회원 가입 페이지에서 shkim99라는 이름을 입력하고 엔터를 누른 뒤, localhost:8080 페이지로 갔다가 회원 목록을 눌러보니까 위 사진처럼 인덱스 번호가 2가 아닌 33으로 할당되어 있더라구요... 왜 그런걸까요??코드도 처음부터 끝까지 김영한 강사님과 똑같이 설정했습니다.  그리고 추가적으로 이번 강의의 내용은 실무에서 사용하지 않는 건가요?? 강사님께서 처음에 강의 시작하실 때 "고전 방식이라 우리 선배들은 이렇게 개발했구나~ 하면서 편하게 들으세요." 라고 하셨는데 이번 강의 내용 전체에 대한 말씀이신지 궁금하네요. 

클라이언트(안드로이드)가 카카오에서 발급받은 엑세스토큰을 백으로 주는 상황일 때강의영상 토큰 발급 구현 (1), (2)는 작성하지 않아도 되는걸까요??

학습하는 분들께 도움이 되고, 더 좋은 답변을 드릴 수 있도록 질문전에 다음을 꼭 확인해주세요.1. 강의 내용과 관련된 질문을 남겨주세요.2. 인프런의 질문 게시판과 자주 하는 질문(링크)을 먼저 확인해주세요.(자주 하는 질문 링크: https://bit.ly/3fX6ygx)3. 질문 잘하기 메뉴얼(링크)을 먼저 읽어주세요.(질문 잘하기 메뉴얼 링크: https://bit.ly/2UfeqCG)질문 시에는 위 내용은 삭제하고 다음 내용을 남겨주세요.=========================================[질문 템플릿]1. 강의 내용과 관련된 질문인가요?

- 학습 관련 질문을 남겨주세요. 상세히 작성하면 더 좋아요! - 먼저 유사한 질문이 있었는지 검색해보세요. - 서로 예의를 지키며 존중하는 문화를 만들어가요. - 잠깐! 인프런 서비스 운영 관련 문의는 1:1 문의하기를 이용해주세요. social Login 연동 구현을 알고 싶어 해당 강의 부분만 수강하고 있습니다.강의에서 keycloak에 설정에 관해 이전 강의 시간에 했기 때문에 바로 넘어가셨는데 혹시 어디 부분을 참고하면 알 수 있나요?++ keycloak 설치 및 실행하는 첫 강의는 확인하고 따라 했습니다
