 제가 community version을 사용 중이라 이니셜라이져에서 파일 만들어서 오픈 하는 방식으로 프로젝트 생성을 했는데 404에러도 나오지 않고 컨트롤러를 만들어도 우측 상단에 런버튼이 작동 하지 않습니다. 혹시 다른 설정해야 할 부분이 있을까요?

안녕하세요 토비님먼저 좋은 강의 만들어주셔서 감사드립니다.스프링의 기본부터 다시 배우고자 해당 강의를 신청하게 됐습니다. 다름이 아니라 혹시 강의 내용과 pdf 강의 자료를 제 블로그에 정리해서올려도 되는지 여쭙고자 글 남겨드렸습니다.다른 분들과 공유보다는 스스로 복습하는 용도로 글을 작성하는 목적이 크지만 인터넷에 올라오는 내용인 만큼 먼저 허락을 구하고자 합니다.(강의 내용과 강의 자료를 그대로 복붙하지는 않고 스스로 정리한 다음 포스팅 하고자 합니다.)최대한 지양하겠지만 필요하다면 pdf 파일 속 그림이나 사진을 올릴때도 있을것 같습니다.당연히 출처는 남기겠습니다.만약 불가하시다면 비공개 처리하여 공유 및 열람이 안 되도록 조치해놓겠습니다. 

@Test void conditional() { new ApplicationContextRunner().withUserConfiguration(Config.class) .run(context -> { assertThat(context).hasSingleBean(MyBean.class); assertThat(context).hasSingleBean(Config.class); }); new ApplicationContextRunner().withUserConfiguration(Config2.class) .run(context -> { assertThat(context).doesNotHaveBean(MyBean.class); assertThat(context).doesNotHaveBean(Config2.class); }); } 토비님이 작성해주신 코드에서 Config2 를 테스트 할때 Config2의 빈의 생성유무를 체크를 해야할 거 같은데 맞을까요?26번째줄입니다.맥락상 FalseCondition인 Config2를 ApplicationContext에 빈이 생성되어 있는지 생성 되지 않았는지에 대한 맥락에서 테스트의 목적은 생성되지 않아야 함으로 assertThat(context).doesNotHaveBean(Config2.class);이게 맞을거 같습니다.

서버에서 session이 어떤식으로 관리되는지 궁금합니다.궁금하게 된 이유는 저희가 흔히 인증방식을 jwt token을 쓸 경우 session less때문에 서버에 부하를 줄인다고 알려져 있는데spring boot를 포함한 다른 서버들도 각 요청마다 HttpServletRequest.session이 담겨져서 오고있고 실제로 컨트롤단에서 사용할 수 있는데 단지 session객체를 참조하지않고 사용한다는 것 만으로 세션을 안쓰기 때문에 서버에 부하를 안준다고 말할 수 있는 걸까요? 제가 생각하는 서버에 부하를 안준다는건, session객체 자체가 생성되지 않아야 부하가 안생긴다는 말이 자연스러울거 같은데, 단지 session객체를 참조해서 쓰지 않는다는 이유만으로 서버의 부하가 없다고 볼 수 있는지 (체감이 될 정도) 궁금합니다.아마 제가 session에 대한 이해도가 부족해서 드는 궁금함 같습니다. 좋은 강의 만들어주셔서 감사합니다.

 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.

 안녕하세요. 토비님스프링부트로 api테스트시에 가끔식 400 Bad Request 가 나오는데요.호출하는 header와 body는 모두 동일한데, 2~30번 호출 중에 한번씩 튀어나오는 경우는 어떤 설정에 문제일까요?api 내용은 별게 없고 로그를 다 찍기도 전에 앞에서 400에러가 나는 상황입니다. 혹시 관련해서 경험하신 바가 있으신지 궁금합니다.

  토비님 안녕하세요. intellij CE 버전에서 spring initializr 로 생성한 프로젝트 실행 시 궁금한게 있습니다. ultimate 버전은 영상에서처럼 run 할 때 우상단에 spring 아이콘이 있고 springboot 플러그인이 적용되어있는데, CE 버전은 그렇지 않고 따로 Run Configurations 가 설정되어있지 않아 아주 동일한 방법으로 실행할 수는 없었습니다. (영상의 "HellobootApplication" 대신 "Current File"로 표시되어있고 실행버튼이 비활성화 되어있습니다.) 일단 main 메소드가 있는 Application.java 파일에서 코드 왼쪽의 실행버튼으로 실행했는데 이렇게 해도 상관 없는건가요? Ultimate 버전과 달리 CE 버전에서 놓치고 가는게 있는지 궁금해서 여쭙니다. 좋은 강의 해주셔서 감사합니다 ~

안녕하세요, 강사님.섹션 9-2, DataSource 자동 구성 클래스에서, connect() 을 테스트하는 코드에서 yml파일을 이용했을 때, 테스트 실패를 하여 질문글 드립니다.먼저 강의와 동일하게 properties 파일을 이용한다면 정상적으로 테스트가 통과됩니다.application.propertiesDataSourceTest평소에 yml 파일을 더 선호하여, yml 파일로 변경한 후, 테스트 코드 상에서 @TestPropertySource("classpath:/application.yml") 로 classpath를 properties에서 yml로 바꿨을 뿐, 기존과 동일한 환경에서 테스트를 진행해봤습니다. application.ymlDataSourceTest하지만, 아래와 같은 에러 로그가 발생하며

 지난번에 말씀해주신 부분들은 다 수정 처리 해서 했는데 이번에 jdbc를 연결하면서 이상하게 build.gradle도 다시 재실행하고 h2 관련 디펜던시도 다 적용을 했는데, 서버 자체는 잘 실행되는데 DataSourceTest가 지금 실행이 안되서 이렇게 질문드립니다. 뭔가 connect를 잘 못불러오는거 같은데 봐주시면 감사합니다!깃허브 주소는 https://github.com/ted7088/hellospring_toby_study 입니다...

 앞서 수강생처럼 contextPath 부분이 value를 잘 읽어오지 못해서 질문드립니다... PropertyPlaceHolderConfig를 추가하고 META-INF에도 추가를 했는데 contextPath 값을 그대로 가져오지 못해서 이렇게 질문드립니다.깃허브 링크 남겨드립니다. 감사합니다!https://github.com/ted7088/hellospring_toby_study

 제가 강의 들으면서 공부할때 매번 깃에다 올리고 커밋 후 푸시 하는 작업을 통해 두대의 컴퓨터에서 작업을 진행했는데, 색션 7,8을 어느 한 컴퓨터에서 듣고 다른컴퓨터에서 깃에서 프로젝트 업데이트 하니깐 hellobootapplication 이 실행이 안됩니다... 오류 사항은 Description:Web application could not be started as there was no org.springframework.boot.web.servlet.server.ServletWebServerFactory bean defined in the context.Action:Check your application's dependencies for a supported servlet web server.Check the configured web application type.종료 코드 1(으)로 완료된 프로세스이렇게 나오는데 혹시 이유를 알 수 있을까요?깃에서 가져와서 그런지 HellobootApplication에 환경변수를 추가해도 이상하게 안되더라고요...기존에 한컴퓨터는 실행이 지금도 잘되는데 다른컴퓨터에서는 이런 오류가 걸려서 질문드립니다

jdk는 11.0.18로 사용중이고 sdk install springboot로 최신버전을 설치하는 것은 가능한데 버전을 지정하면 오류가 발생합니다. 최신 버전(3.1.0)으로 진행해도 될까요?

 spring boot 3.0 버전 부터 CLI 를 통한 run 명령어가 사용불가능한 것으로 보이는데 대체할 수 있는 방법이 있을까요?https://github.com/spring-projects/spring-boot/issues/32263

 spring 명령어를 쳐서 확인하려는데 오류가 발생했습니다. 이 버전의 Java Runtime은 최대 55.0까지의 클래스 파일 버전만 인식한다고 합니다. Java SE 11 = 55이란거 까진 알았는데 그 다음에 어떻게 해야 될까요? 고민과 검색 많이하다가 답이 안나와 여쭤봅니다.

 안녕하세요.단위 테스트를 작성하여 확인한 후, 통합 테스트를 진행해보고 있습니다.궁금한 점은 통합테스트 실행시 단위 테스트들이 실행되지 않는 다는 것인데 별도의 설정이나 콜이 필요한가요? 제가 이해한 바로는 @SpringBootTest 가 붙은 통합테스트 진행시 @Test가 붙은 단위 테스트들을 contextload()에서 자동으로 실행 되는 것으로 알고 있습니다.현재 SpringBootTest쪽에는 별도의 코드가 있진 않고 빈 contextload()만 존재합니다. 조언 부탁드리겠습니다. 감사합니다.
