data class BookRequest( val name: String, val type: BookType,) 웹에서 폼에 책이름, 타입을 컴퓨터로 선택해서 요청을 보내면컨트롤러에서 BookRequest에 enum 타입인 type에 자동으로 값이 받아지는건가요?별도로 converter를 구현안해줘도 되는것인지 궁금합니다

안녕하세요Optional 소개 강의 13분쯤에 "Map의 가장 큰 특징이 key는 null이 아닙니다"라고 하셨는데 HashMap은 key값으로 null이 가능한 것으로 알고 있는데, (Hashtable은 key로 null이 불가능하고요) 혹시 제가 뭔가 잘못 알고 있는걸까요?

[질문 템플릿]1. 강의 내용과 관련된 질문인가요? 예2. 인프런의 질문 게시판과 자주 하는 질문에 없는 내용인가요? 예3. 질문 잘하기 메뉴얼을 읽어보셨나요? 예[질문 내용]생각해봤는데 예제라서 상관은없지만 Team에 @OneToMany(mappedBy = "team") private List<Member> members = new ArrayList<>();이 부분에서 하나의 팀에 똑같은 회원이 중복안되도록 Set<Member>로 하는것도 괜찮을까요?아니면 제가 모르는 뭔가 때문에 상관 없을까요?

안녕하세요. 우선 좋은 강의 제공 해주셔서 감사드립니다 :) 이번에 회사에서 신규 프로젝트로Client Server (Vue, React, Android, IOS)Back Server (Spring Boot)해당 언어로 구성하기로 결정 되었습니다. 신규 프로젝트에 있어서 가장 중요한 부분이 인증 및 인가 시스템인데요.여기서 우리는 JWT + Spring Security 를 사용하기로 결정되었고특히 Social Login 경우 Grant Type 을 "Authorization Code Grant Type" 을 이용하기로 했습니다.아무래도 Authorization Code Grant Type 이 가장 안전하기 때문 입니다. 앞써 말씀드렸지만 Client Server 를 vue, react, Android, ois 를 이용 계획이고Authorization Code Grant Type 을 동시에 이용하면서 인증 처리 할 예정인데요. 인증이 성공적으로 완료된다면 자체적으로 JWT 토큰을 생성해서 Access Token 을 만들고 Client 서버 에게 반환 해서 반환 받은 Client 서버들을 Resouce Server 에서 자원을 요청 하는 시스템입니다. 우선 이미지를 보면서 시나리오를 설명 드리도록 하겠습니다. 일반 로그인A 사용자가 아이디 하고 패스워드를 입력 후 Authorization Server(Spring Boot) 로 전송한다. 인증 처리가 완료 되면 A 사용자 그러니깐 Client 서버에게 자체적으로 JWT Token 을 만들어서 Access Token을 전송한다. Client Server 는 자체적으로 만든 JWT Token (Access Token) 을 쿠키에 저장 하고 Resource Server 에 요청 한다. Social 로그인Client 서버 접속한 사용자는 KaKao 소셜 로그인 버튼을 클릭한다. (요청 파라미터는 카카오로 부터 제공 받은 client_id, redirect_uri + response_type 을 'code' 로 지정한다.) KaKao Authorization Server 는 요청 받은 파라미터로 Client 식별하고 사용자에게 kakao 로그인 페이지를 보여드린다. 생략 되었지만 인가 처리되었다면 임시 코드값을 지정한 redirect uri 통해 client server 로 전송한다. 임시 코드를 받은 Client Server 는 자체적으로 구축한 Authorization Server(Spring Boot) 로 전송한다. 임시 코드를 전송 받은 데이터와 client_id, client_secret, response_type 함께 KaKao Authorization Server 로 요청한다 (Access Token 받기 위해) 인증이 완료되면 KaKao Authorization Server 는 Authorization Server(Spring Boot) 로 인가처리가 완료되었음을 의미하는 Access Token 만들어 전송한다. Access Token 을 발급 받은 Authorization Server(Spring Boot) 서버는 해당 Access Token 을 이용해서 인증 처리하기 위해 KaKao Authorization Server 로 요청한다. 인증 처리 완료되었다면 해당 접속자의 유저 정보를 전송 한다. 해당 유저 정보를 이용해서 회원 가입 프로세스 처리 동시에 자체적으로 JWT Token (Resource Server 접근 하기 위한) 을 생성해서 Client Server에 반환 한다. Client Server 는 자체적으로 만든 JWT Token (Access Token) 을 쿠키에 저장 하고 Resource Server 에 요청 한다. 선생님 강의에서는 Client Server 경우 Spring Boot Security 을 이용했던거와 달리클라이언트 서버 경우 Vue, React, Android, IOS 사용 할려고 합니다.그리고 Grant Type 을 "Authorization Code Grant Type" 사용 하기 때문에 일반 로그인 경우는 문제가 없는데Social 로그인 경우 프로세스를 어떻게 하면 잘 구성 될지 제 나름대로 고민을 해보았습니다. Implicit Grant Type 경우를 사용하면 쉽게 처리 할 수 있을것 같은데Grant Type 을 "Authorization Code Grant Type" 사용 할려다 보니 많이 복잡해지고 이렇게 작동이 될지 의문도 들고 이런 저런 생각이 드네요. 또한 Client Server 경우 절대로 client_secret 을 노출 해서는 안되다는 점 제한으로 이러저런 구성하는데 힘이 좀 들었습니다한번 선생님에게 제가 구상한 프로세스를 피드백 받고 싶어 이렇게 질문 드립니다. 항상 소중한 강의 제공해주셔서 감사드리고 답변 부탁드립니다. 감사합니다 :)      

안녕하세요. 고생 많으십니다!현재 저는 스프링 기초 지식이 어느 정도 있는 상태입니다.헌데, 학원 커리큘럼상 servlet / jsp를 활용하여 먼저 세미 프로젝트를 진행한 다음, 스프링 교육을 통해 파이널 프로젝트를 진행합니다.그렇기 때문에 servlet / jsp 관련하여 학습이 필요한 상황인데, 스프링 핵심 원리 - 기본편 강의를 완강하지 않고, 스프링 MVC 1편에 jsp / servlet 항목을 먼저 수강해도 큰 지장이 없을까요?

안녕하세요! 강의에서 말씀해주신대로, 엔티티 레벨에서 단위테스트를 작성해보았는데 단위 테스트에서 이미 여러 케이스 별로 테스트를 작성했다고 했을 때 서비스 계층의 테스트(repository는 mock 사용)에서도 다시 한 번 모든 경계값 등을 고려하여 '빡빡한' 테스트를 작성할 필요 내지는 그럴 가치가 있다고 생각하시는지 궁금합니다.추가로, 서비스 테스트에서 repository는 mock을 사용한다고 했을 때 repository에 대한 테스트는 생략해도 괜찮은건지 궁금합니다!감사합니다.

[질문 내용]jpa 강의를 spring boot 3버전으로 진행중입니다.메뉴얼을 보고 쿼리 파라미터 로그 남기기 중에hibernate6org.hibernate.orm.jdbc.bind: trace로 수정 후 해결하였고, 외부 라이브러리인 p6spy는 적용이 안됩니다.p6spy 버전은 1.8.1을 사용했습니다. 해당 문제 해결방법이 있을까요?

안녕하세요. 신규 프로젝트를 생성하여 강의를 따라하려고 하다가 스프링부트의 그래들과 관련하여 궁금한 점이 있어서 질문드립니다. 인텔리제이의 스프링 이니셜라이저로 스프링부트 프로젝트를 생성할 때 그래들이 두 가지로 나뉘어지더라구요. 확인해보니 Gradle-Groovy가 보편적인(?) 기존 그래들인것 같고, Gradle-Kotlin은 그래들 파일이 build.gradle.kts로 되어있고 문법도 조금 다른것 같았습니다. Gradle-Kotlin에 코틀린이 적혀있다보니 저의 개인적인 생각으로는 이게 코틀린 프로젝트에 좀 더 맞지 않을까?(호환성 등등...) 하는 생각이 들게 되었는데 두 종류 중 어떤것을 쓰는게 더 좋을지, 혹은 어떤것을 쓰더라도 별 문제는 없는지에 대한 의견이 궁금합니다!

@Transactional 지정위치에대해 궁금합니다 6:17초 부분에서 JPA의 변경을 이용할때에는 트랜잭션을 사용하는게 좋다고 하셨는데 그러면 MemberService 레벨에서 @Transactional 를 지정하는게 아닌 직접적으로 JPA를 작동시키는 MemberRepository에서 어노테이션을 지정하는게 더 좋지않을까요

아래 코드에서 Customer 클래스는 Buy, Sell 인터페이스를 구현하고 buy, sell, order 메서드를 갖고 있는데,buyer.sell()은 왜 실행되지 않는건지 궁금합니다.가상메서드에 의해 Customer 클래스의 sell 메서드가 불리는 것이 아닌가요?public class CustomerTest { public static void main(String[] args) { Customer customer = new Customer(); Buy buyer = customer; buyer.buy(); Sell seller = customer; seller.sell(); // 가상 메서드 : 인스턴스의 메서드가 불림 customer.order(); buyer.order(); seller.order(); } }

안녕하세요. 동시성 이슈를 synchronized 키워드를 사용하지 않고 해결해보려고 했었는데요.MySQL InnoDB의 default level은 repeatable_read로 알고 있어서 한 단계 더 높은 수준인 serializable로 설정하면 동시성 이슈를 해결할 수 있을거라 생각을 했었는데요. 그래도 동시성 이슈가 발생하더라구요..@Transactional(isolation = Isolation.SERIALIZABLE) public void decrease(Long id, Long quantity) { Stock stock = stockRepository.findById(id).orElseThrow(); stock.decrease(quantity); stockRepository.saveAndFlush(stock); }제가 뭘 놓치고 있을까요?

안녕하세요!Event와 Member의 N : N 관계를 중간 테이블(EventMEmber)을 만들어서 풀어낼때Event <-> EventMember <-> Member에서Event를 리스트로 조회하려고 하는데 이때 EventDto에 Member의 String name 필드를 리스트로 가져오려고 합니다. 1. @Query("select distinct e from Event e " + "join fetch e.eventMember a " + "join fetch a.member")Event에 중간 엔티티인 EventMember를 fetch join하고 별칭을 사용해서 EventMember의 member를 fetch join 했습니다.fetch join에서 별칭 사용을 권장하지 않고, 컬렉션을 fetch join을 하면 추후 페이징에 문제가 생길 것 같습니다.  2.@Query(value = "select e from EventMember e " + "join fetch e.member " + "join fetch e.event")List<EventMember> eventMembers = eventMemberRepository.findAllEventArtist(); Map<Event, List<String>> events = new HashMap<>(); for (EventMember eventMember : eventMembers) { if (!events.containsKey(eventMember.getEvent())) { events.put(eventMember.getEvent(), new ArrayList<>()); } events.get(eventMember.getEvent()) .add(eventMember.getMember().getName()); } 중간 엔티티인 EventMember로 Event와 Member를 fetch join으로 가져오고 자바 코드로 원하는 응답을 만들었습니다. 혹시 둘중 더 나은 방법이나 더 좋은 방법, 제가 잘못 알고 있는 부분이 있으면 말씀 부탁드리겠습니다 ㅠㅠ 

안녕하세요.Windows 환경에서 프로필 이미지 변경 화면 접속 시, 아래와 같이 Jdenticon이 안보이는 현상이 발견되네요.IDE를 통해 로컬에서 실행하여 확인할때뿐만 아니라 프로젝트를 Dockerizing한 후, 외부 서버에 컨테이너 형태로 띄운 상태에서 접속하여 동작 확인을 해도 동일한 현상이 나옵니다. 이와 반대로, Mac OS 환경에서는 모두 정상적으로 나옵니다.위 현상과 관련하여 뭔가 Dependency가 있는 요소가 있는걸까요?? 브라우저 캐시 삭제를 해봤는데도 마찬가지네요. 구글링해봐도 관련 내용이 잘 나오지도 않고요. 어떻게 해결할 수 있을지 문의드립니다.
