actions에서 state에 접근할 수 없다고 하셨는데요~ context에 보면 state를 가지고 있어서 context.state.news 로 접근이 가능하였습니다.   접근은 가능하지만 이렇게 사용하는게 좋지 않은건가요? 이렇게 접근하는경우 단점이나 문제점은 뭐가있을까요?

public class ComponentFilterAppConfigTest { @Test void filterScan() { ApplicationContext ac = new AnnotationConfigApplicationContext(ComponentFilterAppConfig.class); BeanA beanA = ac.getBean("beanA", BeanA.class); org.assertj.core.api.Assertions.assertThat(beanA).isNotNull(); Assertions.assertThrows(NoSuchBeanDefinitionException.class, () -> { ac.getBean("beanB", BeanB.class); }); } @Configuration @ComponentScan( includeFilters = @ComponentScan.Filter(type = FilterType.ANNOTATION, classes = MyIncludeComponent.class)//, //excludeFilters = @ComponentScan.Filter(type = FilterType.ANNOTATION, classes = MyExcludeComponent.class) ) static class ComponentFilterAppConfig { } }   안녕하세요 강의잘 보고있습니다. 질문이 여러가지가있는데 우선 첫번째로 저는 처음에  @MyExcludeComponent 위에 Target 과 Retention 옵션으로 스캔이 되나 했는데.. 이건 그냥 메타데이터일 뿐이고 실제로는 @Component 인터페이스만 붙여진 것만 컴포넌트 스캔의 대상이다 가 맞나요??   두번째로 그렇다면 위예제에서 MyExcludeComponent 자체는 사실 컴포넌트 스캔의 대상이아니고 IncludeFilter 에 해당하는 MyIncludeComponent 만 수동등록해준건데.. excludeFilter 를 명시적으로 해주나 안해주나 동일한것 맞나요?? 실제 생략하고 테스트돌려도 동일해서요. 감사합니다.  

- 먼저 유사한 질문이 있었는지 커뮤니티의 '자주 묻는 질문'과 '질문 리스트' 그리고 '강의 소식'에서 검색해 보세요.- 수업 관련 질문은, 강의 번호와 스크린샷을 포함하면 더 확실한 답변을 들을 수 있어요.- 서로 예의를 지키며 존중하는 문화를 만들어가요. - 작성한 질문은 답변을 들은 후 절대 삭제하지 마세요, 다른 수강생분에게도 도움이 됩니다.- 인프런 서비스 운영 관련 문의는 1:1 문의하기를 이용해주세요.   객체화하기전에는 얼굴 몸 따로그리면 페인트통가능한데 객체화하면 페인트통 사용이안되요..

1번 예제 HTML <a href="#none" class="show-btn">보이기</a> <a href="#none" class="hide-btn">감추기</a>   <p>     태그선택자 a를 클릭했습니다.   </p>   jQuery $(function () {   $("p").css({"display":"none"});     $(".show-btn").click(function () {     $("p").css({"display":"block"})   });     $(".hide-btn").click(function () {     $("p").css({"display":"none"})   }); });     2번 예제 HTML <a href="#none" class="show-btn">보이기</a> <a href="#none" class="hide-btn">감추기</a>   <div>Box</div>   jQuery $(function () {   $("div").css({"display":"none"});   $(".show-btn").click(function () {     $("div").show()   });   $(".hide-btn").click(function () {     $("div").hide() });       1번 예제하고 2번 예제 둘다 보여주고 감추는 기능을 하는 명령문? 들 인데 2번예제의 jQuery를 1번 예제의 jQuery 처럼 작성해서 실행 시켜봤더니 동작이 안되네요?? 그 이유를 알 수 있을까요??

index.tsx 파일에 const App = () => { const getName = () => { return "test";}  return <div>{getName()}</div> } 예를 들어 위와 같은 구조에서 1. App 컴포넌트 내부에 getName 함수를 정의해서 사용하는거랑 App 컴포넌트 밖에 함수를 정의해서 사용하는 경우 어떤 차이가 있는지 궁금합니다 2. App 컴포넌트 내부에서 함수를 정의하는 경우 App 컴포넌트가 랜더링 될 때마다 getName 함수도 다시 만들어지는 걸로 알고 있는데 이런 일반함수들은 App 콤포넌트 밖에다 정의해도 상관이 없는건가요?   3. 상태를 변경하는 함수인 경우에만 App 콤포넌트 내부에 정의하고 그렇지 않은 경우 밖에다 정의하는게 좋을까요?   감사합니다

먼저 좋은 강의 감사드립니다.  만약 마스터 노드에 급격한 부하로 복제가 지연되고 있을떄 마스터 노드가 다운되어 페일오버가 될경우 지연된 binlog를 어떻게 처리하는 지 궁금합니다. 그럼 수고하세요 

- 학습 관련 질문을 남겨주세요. 상세히 작성하면 더 좋아요! - 먼저 유사한 질문이 있었는지 검색해보세요. - 서로 예의를 지키며 존중하는 문화를 만들어가요. - 잠깐! 인프런 서비스 운영 관련 문의는 1:1 문의하기를 이용해주세요.     샘플 아키텍처를 구현하는 강의로 실습 하는 강의면 좋겠습니다. 추가 강의 부탁드립니다.

개발자가 타입 컨버터를 직접 등록하지 않아도 @ModelAttribute로 커맨더 객체를 받을 수 있잖아요 그러면 @ModelAttirbute는  개발자가 만든 객체여도 자동으로 타입 컨버터가 적용된건가요? 만약 이게 맞다면 타입 컨버터를 개발자가 직접 등록할 때는 @PathVariable / @RequestParam 을 사용할 때만 하면 되나요?

오류로 이렇게 떠요 마지막 부분쯤이었어요 오류 CS0177 제어가 현재 메서드를 벗어나기 전에 'monster' out 매개 변수를 할당해야 합니다.

이상하네요. 생성후 git status 했는데 .gitignore.txt 라고 뜨고 제외시킬 .jpg 도 그대로 뜨네요 .   .gitignore 는 똑같이 원도우 텍스트 파일로 생성했고 안에 *.jpg 라고 입력했는대요.

 제가 14강에서 처음 부분만 보고 readline 모듈을 사용해 node.js에서도 터미널 입력이 가능하다는 것을 알게되었습니다. 그런데 여기서 입력받는 값을 변수로 사용이 가능할까요? 파이썬에서는 아래 처럼 사용가능한 것으로 알고 있습니다. a = input("값 입력 : ") 자바스크립트로 알고리즘 공부하는것을 해보려하는데 알고리즘 공부를 할때 입력값을 자주 사용하더라구요. 그래서 readline 모듈 혹은 다른 방법으로 위에 파이썬 코드처럼 입력값을 변수로 사용할 수 있는 방법이 있다면 알려주시면 감사하겠습니다. 

터미널에 표기 될때 붉은색 부분이 표기 될때도 있고, 아닐때도 있는데, 없애는 방법이 궁금합니다

예제 코드가 나와있는 사이트에 접속은 했는데 파이썬이나 다른 어떠한 프로그램 언어도  사용해본 경험이 없어서 그런지 예제 파일을 어떻게 활용해야하고.. 강의를 통해 배운 내용을 어떻게 활용해서 공부해야 할지 감을 못 잡겠습니다.. 예제 파일이 이런식으로 나오던데 이게 뜻하는게 무엇인가요 ..? 제가 아무것도 쓰여지지 않은 백지에 예제 파일과 똑같이 작성 할 수 있을 때 까지 연습을 해야 하는걸까요?

두 문법에 차이가 어떤건지 알 수 있을까요? 결과값이 다르게 나오는데 이해하기가 어렵네요 ..
