MemberServiceTest에서 BeforeEach에서 새로 객체를 불러오고 AfterEach에선 다음 테스트를 위해 저장된걸 지우는걸로 이해를 했는데 어차피 객체를 새로 만드는데 지우는 과정이 왜 필요한건가요? 그래서 AfterEach 코드를 지워봤는데 회원가입()에서부터 막히더라고요 AfterEach는 테스트가 끝나고 실행되는건데 왜 첫번째 테스트부터 작동에 문제가 생기는건가요?
예시 상황은 여러 학생이 테이블을 공유해서 사용하여 모든 테이블에 student_id 컬럼이 있고 이를 이용해 데이터 사용자를 구별한다고 했을 때입니다. 이럴 때 모든 find, update, delete 절에 where student_id = '1000' 와 같은 조건이 필요하다고 하면 단순히 모든 find문에 findByStudentId 하고 아이디를 넣어주는 수밖에 없을까요? 어플리케이션 사용자 학생 아이디는 properties에 적어놓고 가져와 사용할 것이라 프로세스 실행중에 파라미터로 받아오는 경우는 없습니다.

처음에 로그인시 헤더에 jwt 토큰이 저장되고 securityContextholder, 시큐리티 세션에 저장된 loginUser가 stateless 설정에 의해 삭제 되지 계좌등록 컨트롤러에 @AuthenticationPrincipal로 세션에 저장된 loginUser를 사용이 가능한 이유가 JwtAuthrizaitionFilte에서 아래 코드로 securityContextholder에 인증이나 권한체크용으로 저장 되기 떄문에 사용이 가능한걸까요? 맞는거같은데 확실해지고자 여쭤봅니다... Authentication authentication = new UsernamePasswordAuthenticationToken(loginUser, null, loginUser.getAuthorities()); //강제로 authentication 객체를 생성 SecurityContextHolder.getContext().setAuthentication(authentication); //강제 로그인

Test에서 아래 메서드를 추가하여 메모리에 있는 값을 초기화 시키는 것은 이해했습니다. @AfterEach public void afterEach() { repository.clearStore(); } 그런데, 아래 메서드를 추가하기 전에, 왜 MemoryMemberRepository class에서, 아래 메서드를 추가해야 하는지 모르겠습니다! public void clearStore() { store.clear(); } 제가 Test 코드를 처음 작성하는데 이해가 되지 않아서 질문드립니다! 감사합니다.

자바와 스프링 부트로 생애 최초 서버 만들기, 누구나 쉽게 개발부터 배포까지! [서버 개발 올인원 패키지]
7강에서 PostMapping과 GetMapping에 URL로 /user을 입력했는데 홈페이지에서 사용자 등록버튼을 누르거나 목록창을 눌러도 url은 전혀 변하지 않습니다. url로 클라이언트가 요청을해서 서버가 응답하는 거라고 알고있는데 어떻게 이렇게 작용하는건가요? url이 바뀌지 않아도 요청을 받아들이는건가요?
안녕하세요. 정말 재밌고 알찬 강의 잘 보고 있습니다. 영상에 추가가 안 된 부분인거 같아 질문 올립니다. DataSource 자동 구성 클래스 강의 중에 'DataSourceConfig' 클래스를 정의하고, com.southouse.config.MyAutoConfiguration.imports에 패키지 이름을 추가해줘야 하는데 이 부분이 영상에서 빠진거 같아서요.
Database "~" not found 떠서 오류 뜨시는분들 이렇게 base에 jpashop.mv .db가 생성되지 않아서 생기는 문제같습니다. ./h2.sh로 h2 실행한 후 맥이든 윈도우든 상단이나 우측하단의 h2아이콘을 클릭한 후 create new database를 생성합니다. 여기서 그냥 넣게되면 h2의 bin폴더에 생성되면서 제대로 실행이 안됩니다. 그래서 제가 해결한 방법은 h2폴더의 bin폴더에서를 기준으로 한 절대경로로 base까지 이동한 다음 마지막에 jpashop을 기입한다면 원준님 사진처럼 나옵니다. 그리고 해결됩니다 ex)../../../../jpashop 이런식으로요 강의 듣느라 고생많으신데 빨리 해결하고 넘어가시면 좋겠습니다! 정리하자면 1. ./ h2.sh 실행 2. h2아이콘에서 create new database 3. 절대경로로 h2/bin에서 base경로까지 이동해 jpashop으로 파일이름 넣기 4. jdbc:h2:tcp:// localhost/~/jpashop 이후 실행되실겁니다

엔티티 설계시 주의점 강의 13:52/27:32 부분에서 JPA에서 컬렉션을 표현하는 클래스로 지연로딩 전략을 사용할때 PersistentBag 을 사용하는걸로 알고 있습니다. 컬렉션 필드를 매핑하기위해 toMany 애노테이션인 관계에서는 컬렉션 필드를 PersistentBag으로 관리하는다는데 이걸 set으로 새 컬렉션을 넣는건 예외가 발생할수 있다고 하셨습니다. 그러면 아예 사용할때부터 변경할수 없게 final로 지정을 하는건 안되나요?
안녕하세요 강의에서는 resource 서버가 받은 토큰 검증 과정에서 opaqueToken을 사용하고 있는데요. JWT 경우로 질문을 드리고 싶습니다. JWT토큰도 opaqueToken과 마찬가지로 oauth2/revoke api를 호출하면 정상적으로 meta.invalidated 필드가 true로 변경되는 것을 확인했습니다. 해당 필드가 true로 변경되었음에도 불과하고 resource 서버에 동일한 토큰으로 요청을 보내도 정상적으로 동작하고 있는 것을 확인했는데요. jwtToken 방식의 경우에는 토큰 검증시 최초에만 jwkSet을 가져오기 위해 한번만 authorization server를 호출하고 이후에는 내부적으로 jwtDecoder를 사용해 검증하는 것으로 보입니다. 결론적으로 jwtToken을 사용할때는 oauth2/revoke를 통해 meta.invalidated 값과 무관하게 토큰 만료 전까지는 지속적으로 접근이 가능한 것으로 보이는데요. 제가 이해한 흐름이 맞을까요?
