강의진행중 궁금한게 있어서 문의드렸습니다!강의중에 토큰이 탈취될수도 있다고하셔서 String jws = Jwts.builder() .setSubject(String.valueOf(userId)) .signWith(key) .setIssuedAt(new Date()) .compact();코드를 넣어주셨습니다. 매번 다른 accessToken값이 나올수 있도록이요! 그 결과 로그인 시마다 매번 다른 토큰값이 나오는데, 로그인을 하고나서 기존의 토큰값으로 /foo 메소드를 호출하여도 인증이 되는데 왜 그런걸까요??1. 로그인시 abc토큰이 나와서 abc토큰으로 /foo 컨트롤러를 호출함 인증됨2. 또 한번 로그인시 abcd토큰이 나옴. 그런데 이전 로그인 토큰이였떤 abc토큰으로 /foo 컨트롤러를 호출하여도 인증 성공됨.왜 그런지 궁금합니다!

안녕하세요. Querydsl강의를 수강하고 혼자 개발을 진행하다가 다음과 같은 문제가 발생해서 질문을 남기게 되었습니다. 제 상황은 A엔티티와 B엔티티를 가지고 있고, 둘은 OneToOne관계로 B가 연관관계의 주인인 상황입니다. Repository에는 A와 B의 데이터를 호출하는 Querydsl코드가 각각 존재하며, 이를 Service Layer에서 그대로 Return값으로 받고 있습니다.이들을 멀티쓰레드 환경에서 호출했을 때 B데이터를 호출하는 코드에 Connection leak이 존재한다는 에러가 발생하는 상황입니다. (.yml파일에서 hikari의 leak-detection-threshold을 설정한 상황입니다.)Domain@NoArgsConstructor @AllArgsConstructor @Entity public class A { @Id private Long id; @OneToOne(mappedBy = "a") private B b; private int var1; }@NoArgsConstructor @AllArgsConstructor @Entity public class B { @Id private Long id; @OneToOne @JoinColumn(name = "b_id") private A a; private int var1; }Repositorypublic interface Repository extends JpaRepository<A,Long>, RepositoryCustom { }public interface RepositoryCustom { Dto queryOne(); Dto queryTwo(); Dto queryThree(); }public class RepositoryCustomImpl implements RepositoryCustom { private final JPAQueryFactory queryFactory; public RepositoryCustomImpl(EntityManager em) { this.queryFactory = new JPAQueryFactory(em); } @Override public Dto queryOne() { return queryFactory .select(Projections.constructor(Dto.class, a.id, a.var1 )) .from(a) .fetchFirst(); } @Override public Dto queryTwo(){ return queryFactory .select(Projections.constructor(Dto.class, b.id, b.var1 )) .from(b) .fetchFirst(); } @Override public Dto queryThree(){ System.out.println("a.getClass() = " + a.getClass()); System.out.println("b.getClass() = " + b.getClass()); return queryFactory .select(Projections.constructor(Dto.class, b.id, b.var1 )) .from(b) .fetchFirst(); } }queryThree는 queryTwo와 Querydsl코드는 동일합니다. 다만 쿼리를 실행하기 전에 Qtype의 a와 b를 순서대로 한번 호출했다는 부분이 queryTwo와 다릅니다.DTOpublic class Dto { private Long id; private int var1; } Service@org.springframework.stereotype.Service @RequiredArgsConstructor public class Service { private final Repository repo; @Transactional public Dto logicOne(){ return repo.queryOne(); } @Transactional public Dto logicTwo(){ return repo.queryTwo(); } @Transactional public Dto logicThree(){ return repo.queryThree(); } }테스트코드@SpringBootTest @Slf4j public class SimpleTest { @Autowired Service service; @Test void connection_leak_detected(){ Runnable userA = () -> { Dto dto = service.logicOne(); log.info("[Thread A: {}]",dto); }; Thread threadA = new Thread(userA); threadA.start(); Runnable userB = () -> { Dto dto = service.logicTwo(); log.info("[Thread B: {}]",dto); }; Thread threadB = new Thread(userB); threadB.start(); sleep(6000); } @Test void leak_not_detected(){ Runnable userA = () -> { Dto dto = service.logicOne(); log.info("[Thread A: {}]",dto); }; Thread threadA = new Thread(userA); threadA.start(); Runnable userB = () -> { Dto dto = service.logicThree(); log.info("[Thread B: {}]",dto); }; Thread threadB = new Thread(userB); threadB.start(); sleep(6000); } @Test @Transactional void connection_leak_detected_otherCase(){ Runnable userA = () -> { Dto dto = service.logicOne(); log.info("[Thread A: {}]",dto); }; Thread threadA = new Thread(userA); threadA.start(); Runnable userB = () -> { Dto dto = service.logicThree(); log.info("[Thread B: {}]",dto); }; Thread threadB = new Thread(userB); threadB.start(); sleep(6000); } private void sleep(int millis){ try{ Thread.sleep(millis); } catch (InterruptedException e){ e.printStackTrace(); } } }connection_leak_detected를 테스트하면 Connection leak이 발생했다는 에러가 발생합니다.leak_not_detected를 테스트하면 Connection leak 로그가 출력되지 않습니다.leak_not_detected와 동일한 테스트코드에 Transactional을 선언한 connection_leak_detected_otherCase은 Connection leak 로그가 출력됩니다.어떤 이유로 이러한 Connection leak이 발생하는지, 그리고 어떻게하면 이러한 문제를 해결할 수 있는지 궁금합니다..!     

예를 들어 Order와 OrderItem이 있는데 Order의 검색을 동적쿼리로 검색해야해서 querydsl을 사용하고 있는 상황입니다. 그 중 검색조건이 OrderItem의 이름으로 검색해서 Order의 목록을 가져와야하는데 Order와 OrderItem을 조인하고 where절에 OrderItem의 이름으로 조회하는 방법 말고는 없을까요? 그럴 경우 distinct를 쓰거나 따로 중복 제거 로직을 넣어야해서ㅜ 혹시 다른 방법이 있나 문의드립니다.이런 경우에는 양방향 연관관계를 맺어주고 해결해도 될까요?

궁금증이 생겨 한가지 질문할게요.만약 Service 계층에서 validate(), update()라는 메소드가 있을 때 두 메소드 모두 로직 시작부분에 엔티티를 조회한다고 하면 두 메소드에서 모두 select 쿼리가 나갑니다. OSIV 설정을 true로 하면 Controller 영역까지 트랜잭션이 유지 되기 때문에 컨트롤러 안에 xxxService.validate();xxxService.update();이렇게 해도 같은 트랜잭션 안에 있었기 때문에 select 쿼리는 한번만 나갑니다. 하지만 OSIV 설정을 false로 하면 Controller 영역까지 트랜잭션이 유지 되지 않기 때문에 위와 같이 작성하면 select 쿼리가 두번 나갑니다. 이를 해결하기 위해 두가지 메소드를 하나로 합쳐 Controller 영역에서 사용할 수 있습니다.xxxService.updateSet();하지만 이때는 입력 받아야 하는 인자 수가 많을 경우 3, 4개 넘게 받는 경우가 생겨 질문드립니다...쿼리 성능으로는 합치는게 맞지만 구조적으로 이러한 설계가 맞는지 궁금합니다. 감사합니다~!

OrderItem에서 전체가격 조회 메소드입니다.여기서 getOrderPrice()대신 this.OrderPrice를 해도 되는지 궁금합니다

MemberService에서는 member.getId를 해서 id값을 가져와서 확인하는데ItemRepository에서는 item.getId가 null입니다memberService 는 memberRepository에서 저장되고 db에 있는 id를 가져오는게 아니지 않나요?

안녕하세요! 강의 수강 중 궁금한 부분이 있어 질문 남깁니다.테스트 코드 실행 시 콘솔 창의 쿼리가 여러 줄로 format된 형태가 아닌 한 줄로 나옵니다.application.yml 에서 hibernate.format_sql: true를 추가했는데도 적용이 안 되는데 이유를 잘 모르겠습니다.

(예)[질문 내용]여기에 질문 내용을 남겨주세요. 안녕하세요.항상 좋은 강의 감사드립니다.현업에서 업무를 하다보면 package를 도메인별로 분리하고 도메인에 controller, repository, service, entity, dta, dao등 패키지를 구분하고 있습니다.이는 하나의 모든 controller, repository에 담게 되면 유지보수성이 떨어지기 때문인데요.강의에 강사님께서 하나의 패키지에 넣으셔서 질문을 드립니다.MSA구조로 작게 분리한다고 해도 유지보수가 용의하기 위해서는 패키지를 분리하는게 좋다고 생각되는데요.DTA를 controller에 넣는다던지 entity를 모두 하나에 넣고 있어서...현업에서도 이렇게 쓰는게 더 좋은건지,,,아니면 강의에서만 분리하지 않는 것인지 궁금합니다.혹, 강의에서만 분리하지 않는 구조라면sample로 효율적인 패키지 구성을 제공해 주실 수 있나요??
