섹션 4. 회원 도메인 개발] 회원 기능 테스트 강의를 수강하는 중 질문이 있습니다. @ExtendWith(SpringExtension.class) @SpringBootTest @Transactional // for rollback class MemberServiceTest { @Autowired MemberService memberService; @Autowired MemberRepository memberRepository; @Autowired EntityManager em; @Test @DisplayName("회원가입") @Rollback(false) public void signUp() throws Exception { // given Member member = new Member(); member.setName("kim"); // when Long saveId = memberService.join(member); // then Assertions.assertThat(member).isEqualTo(memberRepository.findOne(saveId)); }@Rollback(false) 어노테이션을 사용한 결과 강의와 동일하게 db의 member table에 name = "kim" 이 정상적으로 들어온 것을 확인하였습니다. 그런데 이후 @Rollback(false) 어노테이션을 주석 처리한 뒤 Test를 실행하면, 위에서 저장했던 name="kim" 의 row가 지워진 것을 확인할 수 있었습니다. 여기서 저의 궁금증은, 첫 번째의 결과로 인해 name = "kim" 인 row가 이미 생성이 되었으므로, 2번을 실행할 때 memberService.join 메서드에서 이미 기존의 name="kim"인 데이터가 있으므로 오류를 발생시켜야 한다고 생각했는데요, 결과는 정상적으로 테스트가 수행됩니다.위의 이유를 잘 모르겠습니다.감사합니다.   

title이 글자수 10이 넘지 않으려면Post클래스 title객체에다가 @Max(value=10,"10이 넘으면 안된다") 를 붙이면 해결되지 않을까요??만약 기존에 있던 글들이 글자수 10이 넘으면 오류가 날테니? 그에따른 try catch문으로 substring적용해서 글자 수 줄여주고요!

안녕하세요. 강의 영상보고 data jpa 를 사용해 프로젝트 진행중에 있습니다.다름이 아니라 카운트 쿼리에countQuery = "SELECT count(a) from Article a inner join fetch a.content where a.category =:categoryId and (a.title like %:keyword% or a.content.content like %:keyword%) join fetch 하면 에러가 발생하였고, 해다 에러 발생 이유는 구글링 후에 확인할 수 있었습니다.이유: 그런데 여기서 문제는 fetch join은 객체 그래프를 조회하는 기능이기 때문에 연관된 부모가 꼭 있어야 합니다. 그런데 수를 뽑는 count(u)로 조회 결과가 변경되어버렸기 때문에, 오류가 발생한 것이지요.그런데 하나 의문점이 생깁니다.해당 쿼리 내용을 보면, join 한 엔티티의 요소를 where절에서 찾고 있습니다.( a.content.content like %:keyword%)그런데 제가 알고 있는 개념으로는, 기본 Lazy loading 을 사용하게 되면, 연관되어 있는 엔티티를 프록시로 가져오는 것으로 알고 있습니다.그렇게 되면 저 where절의 부분에서 content가 프록시로 들어갔기 때문에, 올바르게 동작하면 안된다고 생각합니다.fetch를 사용하지 않아도, inner join으로만 쿼리가 날라가도, 쿼리 자체는 전부 실행되는 것인가요?그런데 가만히 생각해보면 그런 방식이라면, 지연로딩을 사용하는 방식이 사용자가 필요로 하지 않는 정보까지 join 하는 데이터베이스의 부하를 줄이기 위해 이렇게 하는 것으로 알고 있는데, fetch를 사용하지 않아도 데이터베이스에는 완전한 쿼리가 날라간다면, 이걸 굳이 스프링이 proxy로 끼워줄 필요가 있나? 하는 생각도 듭니다. 따라서 요약해보면,카운트 쿼리에서 조건에 따라 count 가 달라지므로, join을 할 때 fetch 를 넣지 않아도, 올바르게 작동하는 것이 맞는지맞다면 fetch를 사용하지 않아도 실제 데이터베이스에는 join 연산이 항상 일어나는 것이고, 대신 엔티티에 반환 해 줄 때, 프록시로 들어가는 것이고fetch 를 사용하게 되면 나왔던 모든 결과가 엔티티로 들어가 는 것이 맞는지 입니다.jpa 책이랑 웹 전부 뒤져봤는데 이 부분이 약간 모호해서 질문드립니다!

엔티티 설계를 강의를 들으면서 엔티티끼리의 관계(다:다, 1:다, 1:1 등등)양방향관계, 단방향관계 @Embedded@JoinColumn등을 잘 이해하지 못하고 클론코딩 하기 급급했는데 일단 이 활용편 강의를 마저 듣고 기본편을 들으면 될까요 ?

 선생님 안녕하세요 좋은 강의 제작해주셔서 정말 감사합니다. @ConditionalOnMissingBean 관련 궁금한 사항이 있습니다.수업에서는 아래처럼 ServletWebServerFactory 빈을 직접 만들었기에, @ConditionalOnMissingBean 주석 역시 직접 붙이셨습니다.@MyAutoConfiguration @ConditionalMyOnClass("org.apache.catalina.startup.Tomcat") public class TomcatWebServerConfig { @Bean("tomcatWebServerFactory") @ConditionalOnMissingBean public ServletWebServerFactory servletWebServerFactory() { return new TomcatServletWebServerFactory(); } } 그럼 위처럼 직접 생성한 auto config 파일이 아니라, 스프링부트 자체의 auto config 클래스에도 자체적으로 @ConditionalOnMissingBean 주석이 붙어있다고 생각하면 될까요?가령 스프링부트 프로젝트에서 자체 Tomcat 컨테이너를 만들면, 기존 springboot-starter의 톰캣과 충돌이 일어날 거라 생각되는데, @ConditionalOnMissingBean 이 미리 starter하위에 설정돼 있어서 충돌을 회피할 수 있는 것인지 궁금합니다.!

9:08쯤 생성자 오류 부분이 왜 발생하나요??이미 post 필드 외 필드들에 대한 생성자는 annotation에 의해 생성되어 있는데 갑자기 왜 오류가 발생하는지 이해가 되지 않습니다..

K8S나 Docker Swarm 없이 2대 이상의 Host PC에 Multi Cluster를 구성할 수 있을까요?혹시 2대의 PC에 각각 Docker를 설치하고, 여기에 분산되서 올라간 Container들을 하나의 Network으로 묶는것이 가능한가 해서요.방법이 있으면 알고 싶습니다

 강사님께서 application.properties는 스프링 프레임워크의 기본 동작 방식이 아니다스프링 부트 초기화 과정에서 추가 해주는 거라고 말씀해주셨는습니다. @ContextConfiguration는 통합 테스트를 위해서 ApplicationContext를 로드하고, 구성요소 클래스를 넘겨주면 빈을 등록해주는거 같더라구요 SpringApplication.run을 할경우에는Environment 구현체는 ApplicationServletEnvironment가 빈으로 등록이 되고,@ContextConfiguration로 테스트를 할경우에는Environment 구현체는 StandardEnvironment 구현체가 빈으로 등록되는걸 확인했습니다.그래서 Enviroment 구현체가 등록이 되면application.properties를 가져올수있지 않나? 라는 생각에 해당 구현체를 찾아보니StandardEnvironment 는 propertySource를 받지 않는걸 확인했습니다. 제가 궁금한건1.같은 구성 정보 클래스를 넘겨주고 빈으로 등록을 했는데 구현체가 달라지는지 궁금합니다.2.스프링부트에서 테스트를 하는데@TestPropertySource를 따로 명시적으로 메타어노테이션으로 선언해서 사용하는 이유가 궁금합니다.  

안녕하세요? 먼저 좋은 강의 감사드립니다. 실무에 많은 도움을 받고 있습니다.OAuth2.0 Roles(Resource Owner, Resource Server, Authorization Server, Client)의 개념에 대해 궁금한 점이 생겨서 아래 예시와 함께 질문드립니다.카카오톡과 연동한 게임을 보면 게임내 순위 화면에 카카오톡의 프로필 사진이 사용되는 것을 알 수 있는데요.이 경우 카카오톡의 OAuth2.0 인가 서버가 사용자 인증의 역할과 함께 리소스 서버(프로필 사진 제공)의 역할도 함께 수행하는 것으로 보이는데요 이게 맞을까요?감사합니다.

안녕하세요!제가 강의를 다 듣고 난 뒤 추가로 공부를 해볼 생각으로catalog-service 에서 example-catalog-topic 를 받은 뒤상품의 개수를 파악 후 재고 유무의 따라 order-service 에주문 상태를 전달 해주는 example-order-topic 를 만들어 구독 중인 order-service 에서example-order-topic 에서 전달 받은 주문 상태를 업데이트 하는 로직을 구현하려고 했습니다.로컬에서 order-service 와 catalog-service 의 consumer groupId 를 consumerGroupId 로 통일해서 사용 했을 때는 괜찮았으나, docker 에 올리니 example-order-topic 이 생성은 됐으나 구독 및 전달이 되지 않더라구요.... 혹시나 해서 order-service 의 consumer groupId 를 consumerGroupId2 로 변경하여 docker 에 올리니 정상 작동이 됩니다. 혹시 각각의 service 는 groupId 를 다르게 해주어야 할까요??

 아래 블로그 참고해주세요. 저는 이걸로 해결했습니다.https://dkswnkk.tistory.com/672

 public Long save(Member member) { em.persist(member); return member.getId(); }리포지토리에 이 코드가 Member를 반환하지 않는 이유를 설명하면서 커멘드 메서드와 쿼리의 분리를 언급하셨습니다. 그래서 코드가 아무 값도 반환을 하지 않는 코드를 작성하실 줄 알았는데, 또 다음 설명에서 Id를 가져와 반환한 이유를 설명해주셨습니다. 그럼 Member 반환하는 코드는 CQS에 위배되지만, Id를 가져와 반환하는 것 까지는 CQS에 부합하는 코드라는 설명으로 이해해야하는 것인지 혼동됩니다. 제가 이해하기론 설명하고 반대되는 코드라고 생각되어 질문을 남깁니다. CQS에 대한 설명은 하셨지만, Id 정도는 의도가 있으니 Query해도 된다. 정도로 이해하면되는걸까요? 제가 이해못한 부분이 있다면 설명 부탁드리겠습니다. 감사합니다.
