안녕하세요. JPA를 수강하고 '도메인 주도 개발 시작하기'라는 책을 읽었는데요.궁금한 점이 생겨 글을 남기게 되었습니다.JPA의 엔티티와 값 타입에 대해 읽게 되었는데요.애그리거트[루트 앤테티]를 뺀 나머지는 구성 요서는 대부분 밸류이다. 라고 하여 라이프 사이클이 다르면 루트 엔티티로 해야 되고, 같으면 @Embeddable 애너 테이션을 사용하여 값 타입으로 구현해야 된다고 보았습니다. 강의에서는 주소를 구현할 때 잠시 사용하였던 걸로 기억하는데, 어떤 게 맞는지 궁금하여 글을 남기게 되었습니다.

잘되다가 등록 후 조회에서 막히네요ㅠㅠ부탁드립니다...!!https://drive.google.com/drive/folders/1_dcicJUyawOjH4ZO4kd7Tq8REtaDwU6O?usp=drive_link

강의자료를 보면 ItemRepository 클래스에는 private static final Map<Long, Item> store = new HashMap<>(); 이렇게 static final 로 설정하고 MemberRepository 클래스에는 private static Map<Long,Member> store = new HashMap<>(); final이 없는 static으로만 설정했는데 두 방식을 굳이 final 있고없게 설정한 이유가 따로 있을까요??

server 프로젝트 톰켓 연결해서 실행하니깐 서블릿은 동작하는데 index.html 파일은 "HTTP 상태 404 – 찾을 수 없음" 이라고 뜨네요.webapps 폴더에 다른 html 파일을 만들어 넣어도 동작하지 않아요..별도의 설정이 필요한 부분이 있을까요?

안녕하세요 회원 서비스 테스트 강의 듣다가 이해 안가는 부분이 있어서 질문드립니다12:11 에서MemoryMemberRepository memberRepository = new MemoryMemberReposiory(); 이 코드를 왜 작성해야하는지 이해가 안갑니다. clearStore()를 할거면 그냥 위에 적힌 memberService.memberRepository.clearStore(); 로 해도 같은 기능을 하는 코드가 아닌가요? 그리고 memberService.memberRepository를 사용하면 하나의 회원repository instance만 사용하므로 회원 서비스 코드를public class MemberService{ private final MemberRepository memberRepository; public MemberService(MemberRepository memberRepository){ this.memberRepository = memberRepository; } }위와 같이 작성하지 않아도 되는거 아닌지 궁금합니다

IDE를 보니 유용한 플러그인들이 보이는 것 같아요.궁금합니다...!

사용자가 많지 않고 일반 커뮤니티 같은 경우에는 좋아요 개수가 많이 몰릴 일이 없다고 생각해서 PessimisticLock을 적용하려고 합니다. 제가 생각했을 땐 인스타나 그런 대규모 사이트의 좋아요는 PessimisticLock을 적용하면 성능 저하가 뚜렷하게 나타난다고 생각합니다. -> 레디스 사용이 베스트토이프로젝트 규모의 SNS는 PessimisticLock으로 구현하는게 비용도 들지 않고 데이터 정합성이 보장된다고 판단했습니다.혹시 제가 틀린 거나 더 나은 방법이 있을까요?항상 감사합니다! 아 추가로 newFixedThreadPool은 왜 32로 설정하는지도 궁금합니다!!

(예/아니오)[질문 내용]웹서블릿 url이 잘 이해가 안됩니다.예를 들어, test.html 이라는 웹 페이지를 만들고 이 웹페이지에서 로직을 수행하기 위한 자바 코드를 생성한다면 @WebServlet(name="test", urlPatterns="/test.html");을 이용해서 동작을 수행한다고 이해했습니다. 이때, "/test.html"이라는 url은 언제 어디서 어떻게 만들어 지는건가요??  제가 이해하기로는 아래와 같이 이해했는데 아닌거 같더라구요1../test.html이라는 url 생성 2 test.html 웹 페이지 코드 생성 3.WebServlet을 통해 해당 웹페이지에서 동작 수행그렇다면 강사님께서 강의에서 사용하시는 url은 어디서 어떻게 얻어오는 건가요?WebServlet의 url 패턴에 넣으면 자동으로 url을 생성하는 건가요?설명 부탁드립니다
