안녕하세요.오늘도 질문을 남기러 왔습니다. 자주 올려서 죄송합니다ㅠ저는 이제 국비지원학원에서 JSP + SERVLET을 기반으로하는 팀 프로젝트를 마치고 스프링 강의에 들어갑니다.학원 강의를 따라가기 위해, 김영한 강사님의 스프링 입문, 스프링 핵심 원리(기본편) 강의로 스프링을 예습을 해둔 상태입니다.원래대로라면 다음 강의로 스프링 MVC 1편을 들을 예정이었지만, 강사님 조언에 따라서 야생형 코스를 밟고자합니다! 저 같은 상황이라면 바로 JPA 활용 1편으로 넘어가면 되는게 맞을까요? 학원 커리큘럼이 mybatis 기반이라 JPA를 선행학습하는게 맞나 고민이 생겨서 질문 드립니다 ㅠㅠ...

여기 두 개에서 코드 오류떠요..!이유를 모르겠어서 질문합니다..

학습하는 분들께 도움이 되고, 더 좋은 답변을 드릴 수 있도록 질문전에 다음을 꼭 확인해주세요.1. 강의 내용과 관련된 질문을 남겨주세요.2. 인프런의 질문 게시판과 자주 하는 질문(링크)을 먼저 확인해주세요.(자주 하는 질문 링크: https://bit.ly/3fX6ygx)3. 질문 잘하기 메뉴얼(링크)을 먼저 읽어주세요.(질문 잘하기 메뉴얼 링크: https://bit.ly/2UfeqCG)질문 시에는 위 내용은 삭제하고 다음 내용을 남겨주세요.=========================================[질문 템플릿]1. 강의 내용과 관련된 질문인가요? (예/아니오)2. 인프런의 질문 게시판과 자주 하는 질문에 없는 내용인가요? (예/아니오)3. 질문 잘하기 메뉴얼을 읽어보셨나요? (예/아니오)[질문 내용]1. 만약 slice 를 이용해서 0부터 10개의 데이터를 가져오려고 하는데 데이터가 10개 미만으로 있다면 어떻게 처리가 되나요?2. public int bulkAgePlus(int age) { int resultCount = em.createQuery( "update Member m set m.age = m.age + 1" + "where m.age >= :age") .setParameter("age", age) .executeUpdate(); return resultCount; }이 코드에서 resultCount를 return 하는데, 쿼리 문에서 count 와 같은 표현이 안보이는데 어떻게 개수를 return 할 수 있나요?

(예/아니오)[질문 내용]1. @Entity 의 역할을 영속성 컨텍스트에 Entity 넣기, @PersistenceContextContext 의 역할은 영속성 컨텍스트 데이터를 DB 에 넣기로 이해하면 될까요?2. return em.find(Member.class,id); 에서 id 값을 기준으로 해당되는 member 객체가 반환되는 걸로 이해했는데 맞을까요?3. update 는 구현이 따로 필요 없다고 하셨는데, public Member save(Member member) 에서 이 update 기능을 사용할 수 있어서 그런건가요? 

회원가입시 em.persist(member)를 실행하게 되면, 바로 DB에 SQL문이 날아가는게 아니라 2차 쓰기 지연때문에, 트랜잭션이 커밋될때 sql문이 날아가기 때문에, 메소드가 끝나는 시점에 db에 반영되는걸로 아는데, 그렇다면 만약 중복 ID가 이미 등록되어 있는 경우의 exception을 처리해주기 위해서 공통예외처리를 만들어주었다고 한다면, repository에서 exception을 던지는게 맞는지 아니면 service에서 exception을 던지는게 맞는지 궁금합니다.대신, 동시성 처리 문제현상때문에 validateDuplicateMember를 모두 통과했다는 가정하에 질문드립니다.

Order Service URL 주소에서IP:PORT/user/{user-id}/order 이렇게 주소를 주셨는데Restful API 에서 주문 도메인에 있는 정보를 유저 아이디 값으로 가져오고 싶을 때GET ip:port/order?user-id='' 로 가져와도 상관없을까요? 이게 API 디자인 가이드에 위배 되는 행위인지 궁금합니다.
