username뿐만 아니라 password까지 검증되는 이유

미해결

스프링 시큐리티

현재 강의까지의 인증 로직을 보면 @Service @RequiredArgsConstructor public class CustomUserDetailsService implements UserDetailsService { private final UserRepository userRepository; @Override public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException { Account account = userRepository.findByUsername(username); if (account == null) { throw new UsernameNotFoundException("UsernameNotFoundException"); } List<GrantedAuthority> roles = new ArrayList<>(); roles.add(new SimpleGrantedAuthority(account.getRole())); AccountContext accountContext = new AccountContext(account, roles); return accountContext; } } useranme으로만 Account객체를 조회해서 이것이 null인지 아닌지로 사용자를 인증하는 로직으로 이해했습니다. 하지만 로그인 페이지에서 DB에 존재하는 username을 알맞게 입력하고 password는 틀리게 입력하면 인증단계에서 걸러지는걸 확인했습니다. 그렇다면 password까지 검증을 한다는 것인데.. 분명 인증로직으로만 봤을땐 username으로만 인증을 하는것 같았는데 password까지 검증될 수 있었던 이유가 무엇인가요.?

h2에 background

미해결

CSS에 날개를 달아주는 Sass (SCSS)

느낌표에 호버하면 'invalid property value' 라고 나오면서 h2에 background: linear-gradient(left, $color-primary, $color-secondary); 가 안 먹히는 상황입니다 제공해주신 파일의 _type.scss를 그대로 붙여넣기 했는데도 동일하네요 ㅜㅜ 뭐가 문제일까요..

float 속성 상속 관련 궁금합니다!

미해결

float 속성이 상속 될 때에, 바로 아래 선택자 하나에만 상속되나요? 아니면 그 아래 모든 선택자들에게 상속되나요?? 그리고 clear 속성 예제 과정 중, clear div 가 다른 div들 뒤에 가려졌는데, 왜 text는 밖에 나와있는건가요?

강의를 보면 controller에서 작업을 마무리하고, 이후에 코드를 정리하면서 controller, service, repository로 3단 분리를 하시는데, 실제로 처음부터 3단 분리를 하면서 코드를 짜려니까 머리 속에 로직이 잘 정리가 안되더라고요. 처음부터 역할에 맞게 분리를 하며 코딩을 하시는지, 아니면 처음에는 머리 속의 로직을 그대로 쭉 코딩하신 후에 나중에 정리를 하시는 편이신지 궁금합니다.

(예/아니오) 3. 질문 잘하기 메뉴얼을 읽어보셨나요? (예/아니오) 일반적으로 스프링 컨테이너는 싱글톤 기반으로 동작하기에 빈은 모든 쓰레드가 공유합니다. 그런데@PersistenceContext을 통해 주입 받은 EntityManager는 동시성 문제가 발생하지 않는다고 해서 의문이 생겼습니다. 따라서 관련된 내용을 공부하던 중 아래 질문의 영한님 답변을 봤습니다. https://www.inflearn.com/questions/158967/%EC%95%88%EB%85%95%ED%95%98%EC%84%B8%EC%9A%94-entitymanager%EC%97%90-%EB%8C%80%ED%95%B4-%EA%B6%81%EA%B8%88%ED%95%9C-%EC%A0%90%EC%9D%B4-%EC%9E%88%EC%96%B4-%EC%A7%88%EB%AC%B8-%EB%82%A8%EA%B9%81%EB%8B%88%EB%8B%A4 제가 이해한 바로는 private final EntityManager em;를 통해 주입 받은 엔티티매니저는 싱글톤 빈이지만 일반적인 빈들과는 다릅니다. 공통점 : 일반적인 스프링 빈과 엔티티 매니저는 모두 프록시 객체를 주입받는다. 그리고 이는 모두 싱글톤이다. 차이점 : 일반적인 스프링 빈은 호출될때마다 에플리케이션 전체를 대상으로 해당 빈이 스프링 컨테이너에 등록되어 있는지 찾고 있으면 스프링 컨테이너에서 찾아 반환, 없으면 빈을 생성하고 등록(CGLIB 기술) 반면 엔티티매니저는 이해가 가지 않습니다. 책 581 페이지를 보면 A, B 코드에서 호출한 엔티티 매니저는 서로 다르며 , 582에서 멀티 쓰레드에서 같은 코드에서 호출한 엔티티 매니저는 서로 같습니다. 일반적인 싱글톤 빈들이나 엔티티 매니저 모두 싱글톤이며 프록시 객체를 주입 받는 것 같은데 그 안의 원리들이 조금 다른 것 같은데 이 점이 궁금합니다.

나도코딩의 자바 기본편 - 풀코스 (20시간)

안녕하세요, 다름이 아니라 제가 나도코딩 자바(Java) 기본편을 공부하면서, 배열(Array)에 관해 모르는 것이 생겨서 이렇게 질문을 남깁니다. 일반적으로 배열이 String[] array = {...}; 이렇게 선언 되었을 때, array.length를 이용 해서 배열의 길이를 파악하고, array[0] 처럼 이렇게 인덱스로 값의 위치를 파악 하면서 데이터를 읽는다고 알고 있습니다. 반면에 String sentence = "sentence"; 이런 경우에는 같은 length를 쓰지만 String 클래스의 메소드라서 괄호를 나타낸 sentence.length()로 길이를 파악 하고, "..."; 안 문장의 각 글자 별 위치를 파악할 때는 sentence.charAt()을 쓴다 고 알고 있습니다. 제가 이해한 부분이 혹시 맞을까요? 또한 아래처럼 선언된 String[] 배열에서: String[] Java = { "나는 자바가 좋아요" }; Java 배열의 전체 길이를 파악하고 싶다면, Java.length 으로 적는데, 만약 배열 안 문장 "나는 자바가 좋아요" 의 전체 길이를 알고 싶다면 Java[].length()으로 적고, 배열 안에 들어있는 문장 "나는 자바가 좋아요" 에서 각 낱말의 위치를 파악하고 싶다면, Java[].charAt()를 적으면 되는 건가요? 여기서 Java[].부분에는 배열 index를 적고 (예를 들면 Java[0]), charAt()은 "..." 문장의 각 글자 별 인덱스를 적는 방식으로요. 질문이 조금 많이 길었습니다. 하지만 동시에 그 만큼 제가 또한 열심히 배우고 싶다는 열정으로 봐주셨으면 합니다! 게다가 앞으로 다가올 기말시험에서도 배열의 비중이 꽤 크기도 해서, 정말로 잘 배우고 싶습니다! (해외에서 대학을 다니는 지라 지금 이맘때 쯤이 시험기간입니다 ㅠㅠ) 참 얼마 전에, 자바로 소켓 프로그래밍으로 과제를 해야 했었던 일이 있었는데, 그 때 나도코딩님이 업로드 해주신 섹션 12. (Section 12.) 예외 처리 부분이 상당히 많이 도움 되었습니다. 덕분에 과제에서 나쁘지 않은 점수를 받았습니다. 앞으로도 좋은 강의 잘 부탁하고, 진심으로 감사합니다 :-)

데이터베이스 한 칼럼에 다중 값을 넣으려면 어떻게 해야 할까요? 예를 들어서 월, 화, 수, 목, 금, 토, 일을 체크박스로 만들고 여러 개의 값을 체크하면 그 값이 한칼럼에 다 들어간다고 가정했을 때 어떤 방법을 사용해야 할까요?

React key prop 오류 케이스 나오시는 분들 보세요

미해결

비전공자를 위한 진짜 입문 올인원 개발 부트캠프

존경하는 그랩님 Warning: Each child in a list should have a unique "key" prop 오류 케이스에 대해서 조언좀 구할 수 있을까요? ReactDOM.render 방식이 React 18에서 지원하지 않으면서 오류들을 수정했습니다. //[AS-IS] import ReactDOM from 'react-dom'; ReactDOM.render( <React.StrictMode> <BrowserRouter> <App /> </BrowserRouter> </React.StrictMode>, document.getElementById('root') //[TO-BE] import * as ReactDOM from 'react-dom/client'; const root = ReactDOM.createRoot(document.getElementById("root")); root.render( <React.StrictMode> <App /> </React.StrictMode>); 다만 아래와 같은 오류들이 발생을 하였는데요. 구글링에서 찾아보니 각 엘리먼트에 key값을 주는 것으로 해결하라고 하는데요. - 그렇다면 src > main > index.js 에서 각 엘리먼트들에 key 값을 설정해줘야 하나요? - 각 엘리먼트들에 map 으로 되어있는 함수를 지우고.. (product, index) 형태를 key={product.id}>{product.imageUrl} key={product.id}>{ product.name } 형태로 바꾸어 주어야 하나요? - 조금 어렵게 느껴지네요. 해당 부분처럼 바꾸는게 맞는지 조금 조언 부탁드립니다. 현재 제 깃 레파지토리 참조로 첨부드립니다. 도와주세요 ㅠㅠ https://github.com/promotionX/Grabmarket-clinet

싱글톤 질문 드립니다.

스프링 입문 - 코드로 배우는 스프링 부트, 웹 MVC, DB 접근 기술

강의 교재의 "스프링은 스프링 컨테이너에 스프링 빈을 등록할 때, 기본으로 싱글톤으로 등록한다(유일하게 하나만 등록해서 공유한다) 따라서 같은 스프링 빈이면 모두 같은 인스턴스다." 이 문장에서 같은 스프링 빈이면 모두 같은 인스턴스라는 말이 하나의 인스턴스로 자원을 공유한다는 의미 같은데 어떤 경우에 싱글톤을 사용해 자원을 공유하는지 궁금합니다.

강의에서 데이터 베이스를 아직 정하지 못해 인터페이스로 추상화 한다고 설명해 주셨는데 인터페이스 말고 추상 클래스를 사용하면 안되나요? 그리고 만약 데이터 베이스를 정했어도 추상화 할 때 인터페이스를 써야 하는지 궁금합니다.
