setter를 지양하는 이유 중에 하나가 보안성이라고 생각했습니다.그런데 builder를 사용하면 똑같이 보안에 문제가 생기지 않나 의문이 들었습니다.값을 변경하거나 삽입할 때 함수를 따로 만드는 것이 가장 보안성이 좋지만 파라미터가 많을 때 가독성과 편리성을 위해 builder를 사용하는 건가요??

자바 설치를 하며 se11을하려고하는데 자바 유료에 대한 얘기를 듣고나서 java 17 Azul Zulu version 17.07을 했는데 혹시 강의를 듣는데 이상이 없을까요? 혹은무료 유료와 상관없이 se11은 상관이 없나요???

풀이에서 배열을 1부터 N까지 반복문을 돌며 현재 인덱스 값으로 초기화하는데1은 소수가 아니므로 2부터 N까지 반복문을 돌거나, 반복문이후에 A[1] = 0; 으로 초기화해야합니다.왜냐하면 문제의 입력 조건 범위가 1이상 1,000,000이하 이므로 M의 값이 1로 들어올 수 있기 때문입니다.

인터페이스에 findByName(String name) 메소드를 선언만하고 구현체에 무슨 역할을 하는지 상세한 메소드를 오버라이딩 하지 않았는데 쓸 수 있는 이유가 뭔가요?아 강의를 더 들으니 설명을해주시네요 ㅎㅎ..그리고 제가 자바에 아직 잘 모르기 때문일까요? 자바 문법을 처음 공부하고 현재 이 강의를 듣고 있는데 위와 같은 질문들을 잘 모르겠다면 자바를 더 공부해야 하는걸까요?자바 문법만 공부했고 자바에 익숙해지려는 연습으로 자바 코딩테스트를 해보면 자바에 더 익숙해질까요? 아니면 다른 추천 해주실 만한 공부가 있을까요?

강의에서spring.jpa.hibernate.ddl-auto: create 이 옵션은 애플리케이션 실행 시점에 테이블을 drop 하고, 다시 생성한다. 라고 되있는데테스트에서는 @Transaction에 의해 자동으로 메소드가 끝나면 rollback되니까 영향을 끼치지 못한다. 라고 이해하면 될까요??정리하면rollback이 테이블자체를 삭제하는 것은 아니니까 ddl-auto: create와 다르지만 결과에는 영향을 끼치지 않는다. 라고 이해하면 될까요?답변주시면 정말 감사하겠습니다.

Team team = new Team(); team.setName("teamA"); manager.persist(team); Member member1 = new Member(); member1.setName("hello1"); member1.setTeam(team); manager.persist(member1); manager.flush(); manager.clear(); Member m = manager.find(Member.class, member1.getId()); System.out.println("m = " + m.getTeam().getClass()); // Proxy System.out.println("=============="); m.getTeam().getName(); System.out.println("=============="); System.out.println("m = " + m.getTeam().getName());프록시 설명해주실 때 엔티티 매니저의 flush(), clear()를 호출해서 1차 캐시를 비웁니다. 실무에서 이렇게 코드 중간에 1차 캐시를 비우는 일이 잦은가요? 프록시 객체의 존재를 확인시켜주기 위해서 호출하신 건지, 실제로 실무에서 프록시 객체를 사용하기 위해(?) 중간에 flush(), clear()을 사용하는 일이 있는지 궁금합니다 1차 캐시를 강제로 비우지 않는 한은 Query 문 나갈 일 없이 영속성 컨텍스트에서 데이터를 가져오는 일이 대부분일 것 같아서요! 복잡한 쿼리를 JPQL로 작성할 때는 Lazy loading을 적용하고 필요한 객체들이 그때그때 프록시를 통해 초기화되는 일이 자주 있겠지만, 강제로 1차 캐시를 비우는 일은 거의 없지 않나 하는 생각이 들어 질문드립니다.감사합니다.

우선 저는 일반 Maven이 아니라 Maven archetype 으로 프로젝트가 생성이 되더라고요 찾아보니 큰 문제는 아닌 거 같아 진행을 하였습니다.우선적으로 자바 18을 사용하려니 사용이 안돼서 jdk 1.8.0 사용하였고 아래와 같이 h2는 지금 다운받은 서버 버전을 하이버네이트는 강의 pdf그대로 사용하였습니다. 아래처럼 경고는 아니지만 위험표시정도가 뜨는것을 확인할 수 있었고 버전 업그레이드 권장인거 같길래 넘어가고 persistence.xml 설정을 해주었습니다. 우선적으로 저는 resource 밑에 META_INF.maven이라는 파일이 존재하기에 해당 파일에 persistence.xml을 붙여 놓고 빌드를 해주었고 그 상태로 JpaMain을 다음과 같이 작성하고 빌드한 결과 위처럼 강의와는 다른 내용의 오류가 떴습니다. 아무래도 META_INF.maven하위의 persistence 를 인식 못하는것 같아 META_INF 디렉토리를 새로만들어주고 persistence.xml을 옮겨주었지만 그래도 똑같은 오류가 발생합니다 . 이유가 무엇일까요..
