안녕하십니까 영한님!!!잘만 되던 테스트코드가 어느 순간 아래와 같은 오류가 발생합니다. 해결방법들을 찾아보고 시도해보았지만 해결되지 않아 맨 아래에 구글 드라이브 코드 링크 남겨드립니다. java.lang.IllegalStateException: Failed to load ApplicationContext for

 섹션 3 독립 실행형 서블릿 애플리케이션 > 서블릿 컨테이너 띄우기 강의를 듣고나서 든 생각입니다! 왜 Servlet을 써야만할까요? (왜 Spring은 Servlet을 선택한걸까요?)

안녕하세요스프링부트와 JPA 활용1 중 섹션1. 프로젝트 생성 강의를 듣고 있는데요.13:04 부분에 플러그인 롬복을 설치하시는데 앞쪽에서 스프링부트 스타터에서 롬복을 받고 빌드를 했는데 플러그인을 따로 설치해주어야 하는 이유가 뭔가요?빌드한 롬복과 플러그인에서 설치하는 롬복은 무슨 차이인지 어떻게 활용되는지 궁금합니다.

회원생성 부분에서 @PostMapping("/api/v2/members") public CreateMemberResponse saveMemberV2(@RequestBody @Valid CreateMemberRequest request) { Member member = new Member(); member.setName(request.getName()); Long id = memberService.join(member); return new CreateMemberResponse(id); }CreateMemberRequest 가 dto라고 설명하셨는데회원가입시 json값은 값 변경이 없는데 vo가 아닌가요?      

안녕하세요 강사님, 강의 잘 듣고있습니다.강의에서 updateName 메소드를 domain에 작성하였는데 그 이유가 궁금합니다. 다른 기능은 userrepository의 메소드를 활용하는 것 같은데 수정 기능은 다른 이유가 궁금합니다.감사합니다.

먼저 강의 잘 들었습니다.취준 중인데도 이해가 잘 돼서 좋습니다! 다름이 아니라 동시성 제어를 할 때 redis, kafka로도 해결할 수 있다는 것은 알겠습니다. 다만, Lock으로도 동시성 제어도 할 수 있지만 줄줄이 기다리기 때문에 선착순 쿠폰 같은 이슈에 대해서는 비관적 락을 걸 경우 100명까지 순차적으로 느리게 된다는 것으로 이해했는데 맞을까요? 제가 이해한 것이 맞다면 락을 사용하면 많이 느릴텐데 보통 어떤 경우에 락을 통해 동시성 제어를 하고, 어떤 경우에 카프카를 쓰시나요? 같은 경우라도 상황마다 다르겠지만.. 예시를 조금만 들어주실 수 있을까요? 잘 이해를 하지 못해서 질문 남깁니다감사합니다

zookeeper의 경우D:\{home}\kafka_2.13-2.7.0>bin\windows\zookeeper-server-start.bat config\zookeeper.properties이대로 실행하면 아래 파바박 뜨면서 tmp에 zookeeper 폴더도 잘 만들어 지는데kafka는D:\{home}\kafka_2.13-2.7.0>bin\windows\kafka-server-start.bat config\server.properties아무것도 안뜨고 그냥 D:\{home}\kafka_2.13-2.7.0>으로 넘어갑니다 tmp에 폴더도 안 만들어지고요. 딱히 에러가 발생하지도 않습니다. java는 jdk 11.0.2사용 중이고 버전에 문제 없어 보이는데 왜 이러는 걸까요?

fetchtype을 LAZY로 설정했을 경우 N+1문제는 이해했습니다. 그런데 EAGER의 경우 Order를 위한 1개의 select쿼리 뒤에 delivery를 위한 1개의 쿼리와 3중 조인문 2개의 쿼리가 나가고 있는데 (위 사진) join문이 EAGER처리를 위한 쿼리라면 왜 order 조회쿼리 뒤에 바로 나가지 않고 delivery 조회쿼리가 한번 나간 뒤에 나가는건지 왜 delivery에 대한 추가 쿼리는 나가는데 member는 조회쿼리가 나가지 않고 join문이 나가는지 EAGER의 경우에도 모든 연관객체가 영속성 콘텍스트 안에 존재하지 않는다면 정확히 1+N개의 쿼리가 나가는지 (=LAZY와 똑같이 1+N개의 쿼리가 나가는지) 이 세가지가 이해되지 않습니다.EAGER일때 쿼리를 이해해보려고 노력했는데 "LAZY와는 추가쿼리(N)가 나가는 시점의 차이가 있다" 정도 말고는 이해가 되지 않아 질문드립니다.

No matching variant of org.springframework.boot:spring-boot-gradle-plugin:3.1.2 was found. The consumer was configured to find a library for use during runtime, compatible with Java 11, packaged as a jar, and its dependencies declared externally, as well as attribute 'org.gradle.plugin.api-version' with value '8.2.1' but: 현재 SDK는 11 Oracle, Language level은 11- local variable syntax for lambda parameters로 되어있습니다. 원래는 컴파일이 됐었는데 1번 강의(스프링 프로젝트를 시작하는 두 번째 방법) 이후 안되는 것 같습니다. 어떻게 해야할까요?

도서관앱의 포트번호가 8080으로 설정되어 있는것 같은데 포트번호를 변경하는 방법을 모르겠습니다..ㅠ

이번 강의의 native 와 기존에 처음부터 보여주신 uri : file///~~~ 의 방법과 크게 다른점이 뭔가요? 다른점이 없는것 같은데요...

강의 소스 그대로 참고하여 현재 진행중인 프로젝트에CustomUserDetailsService, CustomAuthenticaionProvider, SecurityConfigure 모두 작성하였습니다.그런데 CustomAuthenticaionProvider의 UserDetailsService와 PasswordEncoder의 @Autowired 부분에서 빨간 줄이 그어져 진행이 불가능합니다. 혹시 스프링 부트 버전차이 때문에 그러는 걸까요?? 현재 2.7.1 사용중입니다.실습한 코드 사진 첨부하도록 하겠습니다.configurecontextcustomUserDetailsServicecustomAuthenticationProvider

강의대로 했는데 안되네요.  우선 깃 링크로 접속하여 코드 다운로드받은뒤 압축풀어서 intellij 로 open 하여 해당 강의처럼 maven -> compile 더블클릭 했는데,  잘 돌던중 에러한줄이 뜹니다. /Users/jjeoV/Desktop/jjeoV/인프런/keesun/studyolle-master 2/target/classes/static/node_modules/.bin/jdenticon jdenticon 파일이 없는건가요? 그냥 딸랑 경로하나뜨니까 뭔지 잘 몰르겠네요.  감사합니다.

SpringBoot를 초기화하는 클래스를 살펴보면 BeanPostProcessor 이후 톰캣을 생성하고 톰캣의 dispatcherServlet에 AnnotationApllicationContext를 주입하는 것을 볼 수 있었습니다.그리고 스프링 부트를 사용한 이후에는 빈을 주입 받을 필요가 있는 필터에 대해서 이제는 DelegatingFilterProxy를 사용 할 필요가 없고 필터 또한 빈으로 등록이 가능하다는 것을 볼 수 있었는데요.개인적인 추론으로는 DispatcherServlet이 이미 초기화가 완료된 ApplicationContext를 알고 있고 이에 따라 Filter 등록 시 다음과 같은 과정이 가능해진건지...제 기억상으로는 웹 요청-> WAS -> 서블릿 컨테이너 -> 필터 순서로 기억을 하고 있는데 스프링 부트 애플리케이션 내부로 WAS가 들어오게 되면서 이러한 일들이 가능해진걸까요??

안녕하세요. 좋은 강의 잘 보고 있습니다.토비님이 저술하신 토비의 스프링 3.1의 내용을 보면 BeanFactoryPostProcessor를 구현한PropertySourcesPlaceholderConfigure를 Bean으로 등록할 때는 static 메소드를 통해 등록해야 한다고 봤었습니다.현재 보고 있는 스프링 부트 강의에서는 이를 일반 메소드로 등록하셔서 사용하시던데,스프링 부트에서는 static 메소드로 등록하지 않아도 문제가 없을까요?
