(예)[질문 내용]2:00 부분에서 "생성자가 하나만 있으면 @Autowired를 생략할 수 있다"라고 하셨는데그런 이유가 아니더라도 SpringConfig에 MemberRepository가 스프링 빈으로 등록이 되어 있으니, 그것의 구현체인 JdbcTemplateMemberRepository의 생성자에@Autowired를 붙이지 않아도 되는 거 맞나요?예전 강의에서 SpringConfig에 등록된 MemberService 등은, MemberService 클래스에서 @Service, @Autowired를 지웠던 기억이 있어서 그렇습니다.

중형 테스트는 멀티 스레드, 멀티 프로세스를 허용하는 테스트라고 이해했는데 그 설명을 하시면서 "멀티 프로세스와 멀티 스레드를 사용할 수 있는 완화조건이 생기죠. 이는 다시 말해 h2 같은 테스트용 DB를 사용할 수 있게 된다는 의미입니다." 라고 하셔서요! 혹시 h2를 사용하려면 멀티 스레드나 멀티 프로세스 환경에 있어야 한다고 이해해도 되는걸까요? "h2는 멀티 스레드, 멀티 프로세스 환경에 있어야 하기 때문에 h2를 사용하는 순간 중형 테스트로 보면 된다"로 이해하면 될까요??

제가 이해한 게 확신이 안 들어서 질문드립니다.  @RequestParam은url을 통해서 데이터를 전달하는 방식인 거죠? 즉vi/menu_up?no=8처럼이렇게 데이터를 ?뒤에서 key=value 형식으로 나르는 거죠? 그리고 html에서 링크를 /v1/menu_del(no=..) 이런 식으로 지정하거나,html 태그 form+input이 저런 url을 만들어주는 거죠? (태그 안에 action="/v1/menu_ins"을 적어줄 경우 그 뒤 url에 ?no=8 이런 식의 데이터를 붙여주는 거죠?)

(예/아니오)[질문 내용]스프링 DB 1편 트랜잭션 이해 파트에서 질문입니다."애플리케이션에서 DB 트랜잭션을 사용하려면 트랜잭션을 사용하는 동안 같은 커넥션을 유지해야한다. 그래야 같은 세션을 사용할 수 있다" 여기서 세션의 개념이 정확히 이해가 가지 않아 질문드립니다.찾아본 결과 하나의 커넥션에는 여러 개 세션이 존재할 수도, 아예 없을 수도 있다고 하고, 세션은 전달된 SQL이 실행되는 하나의 논리적 단위라고 합니다. 강의 설명에 따르면 같은 세션을 유지해야만 트랜잭션이 하나의 단위로 처리되기 때문에 이를 위해 같은 커넥션을 사용해야 한다고 이해했습니다. 그렇다면 같은 커넥션을 사용하는 것을 보장했을 때 항상 같은 세션을 사용하는 것도 보장되는 것인가요? 한 커넥션이 여러 세션을 사용하는 경우는 어떤 경우인가요? 여러 세션을 사용하게 되면 여러 세션에서 여러 개의 트랜잭션이 실행될 수 있는 것인가요? 

 47강 회원정보 수정부분에서 session을 왜 추가적으로 넣어주어야 하는지 궁금합니다. 로그아웃 하기 전에 세션은 사라지지 않는 것 아닌가요?

(예/아니오)[질문 내용]추상적인 내용을 코드로 먼저 보여드리고 질문하겠습니다. 먼저 정적인 클래스 의존관계는 다음과 같은데요import hello.core.discount.DiscountPolicy; import hello.core.member.Member; import hello.core.member.MemberRepository; public class OrderServiceImpl implements OrderService{ private final MemberRepository memberRepository; private final DiscountPolicy discountPolicy; public OrderServiceImpl(MemberRepository memberRepository, DiscountPolicy discountPolicy) { this.memberRepository = memberRepository; this.discountPolicy = discountPolicy; }제가 이해한 바로는, DIP 원칙을 지키기 위해 생성자를 통한 인터페이스 주입을 해야 한다고 들었습니다. 다음은 동적인 인스턴스 의존관계 관련 코드입니다.public class AppConfig { public MemberService memberService() { return new MemberServiceImpl(memberRepository()); } public MemberRepository memberRepository() { return new MemoryMemberRepository(); } public OrderService orderService() { return new OrderServiceImpl(memberRepository(), discountPolicy()); } public DiscountPolicy discountPolicy() { return new RateDiscountPolicy(); } }먼저 앱을 실행하기 전인 정적인 클래스 의존관계 단계에서 생성자를 통한 인터페이스 의존성 주입으로 OrderService 객체가 MemberRepository와 DiscountPolicy 인터페이스를 사용할 것이라고 알린 후, 실제로 앱을 구동하면 런타임 환경에서 사용할 인스턴스를 생성하고 이전의 정적인 클래스 단계에서 주입한 것을 구현 객체로 반환하면서 의존성이 물리적으로 연결되었다고 볼 수 있나요? 그래서 정적인 단계와 동적인 단계로 구분한 것인가요?

(예)[질문 내용]build.gradle의 dependencies에 추가한runtimeOnly 'com.h2database:h2'이것이 DB가 제공하는 클라이언트라고 하셨는데 인텔리제이로 실행한 후 웹 브라우저로 localhost:8080에서 회원 등록을 하고, 회원 조회를 할 수 있잖아요? 제가 회원 등록 및 조회를 할 때의 웹 브라우저에 붙어 있는 게 클라이언트이고, h2.bat을 통해 실행시킨 프로그램이 서버라고 보면 되나요? 비슷하게 이해한 건지 궁금합니다

회원등록과 회원목록조회의 경우, 서버기동 중에만 메모리에 등록되고 서버를 죽이면 데이터(?)가 사라지는 걸로 알고있습니다. 근데, 서버재기동 후 이전에 했던 회원정보로 회원가입하면 아래와같이이미 존재하는 회원이라는 에러처리가 발생합니다. 서버 재기동시 store객체는 초기화 되는거 아닌가요?에러처리가 발생하는게 정상인지? 정상이면 왜 그런지 알고싶습니다.

(예)[질문 내용]@Transaction을 사용 시, 스프링 AOP가 적용되어야 하기 때문에 테스트 코드에서는 @SpringBootTest와 함께 트랜잭션 적용에 필요한 다양한 객체를 수동으로 등록하고 적용하는 법을 배웠습니다. (PlatforTransactionManager, DataSource 등) 그러면 테스트 환경이 아닌 서비스 로직에서 @Transaction을 사용할 경우에는 강의에서 진행한 수동 빈 등록 절차를 거치지 않아도 되는 건가요? @Transcation을 썼을 때 트랜잭션에 필요한 빈들을 자동으로 등록한다는 내용이 이 뜻인건지 궁금합니다.
