실전 모의고사 강의 python버전도 출시 예정일까요?

탈퇴하려고 하는데 못찾겠어요 ㅜㅜ

강의 내용과 상관없긴하지만 노이즈가 설명하는 말소리보다 커서 뭐라고 하는지 집중도 안되고, 거슬립니다. 혹시 이부분 개선 안될까요?

안녕하세요 강의 잘 듣고 있습니다. 인터셉터 안에 this를 사용하고 싶으면 바인딩을 어떤 방식으로 하는 것이 좋은지 조언을 구하고 싶습니다. 감사합니다

[질문 템플릿]1. 강의 내용과 관련된 질문인가요? (예)2. 인프런의 질문 게시판과 자주 하는 질문에 없는 내용인가요? (예)3. 질문 잘하기 메뉴얼을 읽어보셨나요? (예)[질문 내용]입문, 핵심원리 강의 다 들었을 때 예를들어 회원시스템, 주문 코드 등등, 제가 강의에서 본 그 코드들을 몇개는 만들 수 있겠지만 처음부터 끝까지는 못만들 것 같아요. 이 상황에서 실습느낌으로 제가 코드를 한번 전체적으로 강의에 쓰인 코드처럼 짜보는 게 맞는건지 질문드립니다. 이 이후 강의를 더 듣고 그 다음 제가 구현해봐야 하는건지 아니면 지금 한번 느낌잡고 가는게 맞는건지 모르겠어서요. 만약 저 혼자 강의 실습코드들 처럼 만든다고 가정했을 때, 강의에 나온 할인, 회원조회 이런 기능들을 만들어보는게 맞겠죠?    

변수를 생성할때, String result; 와 String result = ""; 의 차이점이 뭔가요?

안녕하세요 Spring 기본편들은 후 JPA와 함께 혼자 간단한 토이 프로젝트 진행하다가 해결이 안되서 질문 남깁니다!   간단히 jpaUserRepositroy 빈이 생성됬는지부터 확인해보고 싶은데 어떤 것이 문젠지 모르겠습니다ㅜㅜ     "C:\Program Files\OpenJDK\jdk-11.0.1\bin\java.exe" -ea

항상 고생이 많으십니다.     메인페이지 새로고침시 위와 같은 에러가 나왔는데 어디가 문제인지 못찾고 있습니다.   User에 관련된 부분이 문제인것 같은데 리덕스에선 보시다시피 User 관련이 Null로 나오고 있습니다. 어디쪽을 봐야할까요     워크벤치에서도 UserId 부분이 Null로 표시 돼 있습니다. 터미널에서 서버와 프론트 모두 에러로그 표시는 없습니다.  

고유한 이메일 문제풀이 1번에서는  domaing은 @이후로 substring 하고, local은 앞에서 부터 for 문을 돌면서 +와 @를 만나면 break 하는 방식으로 풀었는데다음 강의 보니까 subString 방식은 이미 풀어져있고, 설명은 없네요

만약에 선택을 잘못해서 뒤로 빽할려면 어떻게 해야 하나요?

안녕하세요. 영속성 컨텍스트와 관련해서 질문드립니다.   위 테스트를 실행하면 name이 마지막에 변경된 lee로 insert 쿼리가 날라갈것이라고 예상했으나 변경 전 값인 park로 insert 되었습니다. 제가 생각하는 insert 과정은 아래와 같은데 혹시 어떤게 잘못되었는지 알 수 있을까요..?엔티티매니저의 persist로 영속성 컨텍스트에 멤버 엔티티 올림 -> 멤버 엔티티의 이름을 lee로 변경 -> 트랜잭션 커밋 -> 영속성 컨텍스트 flush -> 멤버객체(name 이 lee 인 상태)가 insert 됨.   추가로 변경감지도 되지 않는것 같아서 질문드립니다. member1을 insert 하고 영속성 컨텍스트를 clear 한 뒤, 다시 select 해서 name을 변경했는데 update 쿼리가 날라가지 않네요.. jpql로 update 쿼리 짜서 하면 update 쿼리가 날라긴 합니다.. 변경감지는 왜 안되는 걸까요..?

%ls Data를 작성했는데 폴더에 파일도 넣어놨는데 불러오질 않네요...

Appconfig에서 이렇게 쓰셨는데 memberService()는 따로 실행한 코드가 안보이는데 자동으로 실행이 되는건가요? public class AppConfig { public MemberService memberService() { return new MemberServiceImpl(new MemoryMemberRepository()); }} private final MemberRepository memberRepository;public MemberServiceImpl(MemberRepository memberRepository) { this.memberRepository = memberRepository;}

안녕하세요. 강사님 먼저 유익한 강의에 대해 감사드립니다.   강좌에서 spring boot 버전 2.3.8로 진행되고 있는데, 저는 이클립스 환경의 spring boot 버전 2.4.11부터 있어서 2.4.11버전으로 강좌 실습을 진행해도 괜찮을지요?? 강좌에서 최하위(old) 버전을 이용해 실습되어 버전 호환에 우려하고 있었습니다. ㅎㅎ 관련하여 답변 부탁드리겠습니다.
