커맨드와 쿼리의 구분 후 쿼리문 한번 더 실행에서의 궁금증...

미해결

실전! 스프링 부트와 JPA 활용2 - API 개발과 성능 최적화

강의에서 영한님께서는 커맨드와 쿼리를 구분하는 것을 선호하신다고 하셨습니다. 그래서 알아보니 이런걸 CQRS라고 하던데 회원 정보를 update시 update command 메소드 실행 후 보통같으면 update메소드 자체의 반환값으로 member객체나 member id를 받는데, 이것을 명령과 질의를 구분해 memberService.update() 후 memberService.findOne을 실행하면 결과적으로 쿼리문을 한번 더 실행을 하게 되잖아요? update 메소드 내에서도 findOne이라는 메소드를 호출하니깐요. 이렇게 명령과 질의를 분리하였지만 그 대가로 쿼리문을 한번 더 호출하게 된 셈인데 쿼리문을 한번 더 호출해서 명령과 질의를 구분하는 것이 많이 효율적인 패턴인가요?

안녕하십니까? 강사님 수업을 듣는 도 중 똑같이 따라 했는데, Error가 발생해서 질문 드립니다. 먼저 SpringConfig.java 입니다. 위의 Error 내용은 필요 Typedms MemoryMemberRepository인데, 제공된 타입이 MemberRepository여서 Error가 나고 있습니다 MemberService.java 입니다. MemoryMemberRepository.java 입니다. 이렇게 수업대로 따라 했는데, SpringConfig에서 Repository부분에서 Error가 나는데, 왜 나는지가 궁금합니다!

Update 할 때 조건검사(price >= 0) 는 어디서 하는게 좋은 방법일까요?

미해결

실전! 스프링 부트와 JPA 활용1 - 웹 애플리케이션 개발

안녕하세요. 너무 좋은 강의 잘 듣고있습니다 !! :) 강의 마지막부분에서 가장 좋은 방법이라고 말씀해주신대로, Service 계층에 ItemUpdateDto 를 추가하고, 엔티티 클래스에 update() 함수도 만들어서 구현을 했습니다. 여기서 한 가지 궁금한점이 생겼는데요, - price >= 0 - stockQuantity >= 0 - name 은 빈 문자열이 아님(StringUtils.hasText == true) 등의 조건을 검사하여 exeception 을 날리거나, update 를 진행하고 싶을 때 조건검사를 어디서 하는 것이 가장 좋은지 고민이 됩니다. 제 생각에는 크게 세가지 방법이 있을 것 같은데요.. 1. Controller 에서 검사하여, 검증된 값만 DTO에 담아서 service 에 전달한다. 2. service 에서 엔티티의 update() 함수를 호출하기전에 검사한다. 3. 엔티티 클래스의 update() 함수 내부에서 검사한다. 세 가지 방법에대해 제가 고민해본 내용을 말씀드리면.. Book 클래스의 removeStock() 처럼 엔티티 내부에서 검사하고, NotEnoughStockException 같은 에러를 날리는 비지니스 로직을 넣어야할까요? (코드에 일관성이 있도록..) --> 3번 그런데, Controller 에서 미리 검사를 하면 굳이 service -> repository 를 타고 내려가서 select 쿼리를 날릴 필요가 없어지기 때문에 성능상 유리할 것 같다는 생각도 듭니다. --> 1번 두 군데에서 다 검사를 하는 것이 좋을까요? 실무에서는 보통 어떤 방법을 채택하는지 궁금합니다 .

JSP 파일이 Java 코드로 변환된 파일 경로에 대한 질문입니다.

해결됨

스프링 MVC 1편 - 백엔드 웹 개발 핵심 기술

안녕하세요, JSP를 사용한 회원 관리 프로젝트를 진행하던 중 궁금한 것이 생겨 질문드립니다. JSP도 결국에는 프로젝트 실행시 Java 코드로 변환이 되는 것으로 알고 있는데요. 이전에 개인적으로 Eclipse IDE를 사용한 경우 .metadata라는 폴더가 존재했고, 그 안을 들여다 보면 JSP가 Java 코드로 변환된 파일이 존재했습니다. 예를 들어 "sum.jsp" 파일을 작성했다면 "sum_jsp.java" 파일이 존재한 것 처럼요. (이 .java 파일안에서 pageContext, session, application 객체를 사용할 수 있도록 선언되어 있었던 것도 기억이 나네요.) 어느덧 IntelliJ에 익숙해져서 이런 내용을 잊어버린체 코딩을 하는 것 같아 제가 작성한 JSP 파일에 대해 Java 코드로 변환된 파일을 찾아보고 싶은데, 어떤 경로를 통해 찾을 수 있을까요? 미리 답변 감사드립니다.

상속관계매핑 중 JOINED 질문드립니다.

미해결

자바 ORM 표준 JPA 프로그래밍 - 기본편

※ 참고 : MySQL DB 를 사용하고 있습니다. 아래 사진처럼 SecureSetting, SessionTimeoutSetting 2개의 엔티티를 JOINED 전략을 이용해 상속관계 매핑을 해주었습니다. 그런데 3번째 사진처럼 테스트 코드를 작성하고 실행한 결과, ss_configuration 테이블에는 데이터가 잘 들어가는데 ss_session_timeout 테이블에는 데이터가 들어가지 않습니다. 쿼리로 로그 찍힌걸 봐도 insert 쿼리는 2번 나간것을 확인하였습니다. 혹시나 싶어서 SecureSetting 클래스의 @Id 전략을 AUTO 로 바꾸고 하면 잘 되었습니다. JOINED 전략에서는 Id 전략 중 IDENTITY 전략을 사용할 수 없나요?

안녕하세요, 강의 잘 듣고 있는 학생입니다. 다름이 아니라 "스프링 통합 테스트"부분에서 기존 메모리에서 진행하던 테스트를 DB랑 연동해서 진행하는 부분에서, 테스트로 진행한 name이 들어가지 않는 중입니다. 테스트 돌릴시 fail은 따로 뜨지 않고, 잘 넘어가는 중입니다. 그리고 id 시퀀스도 하나 증가해서 잘 되는데 name이 등록이 되지 않더라고요. 따로 프로젝트를 실행해서 웹페이지에서 넣으면 문제없이 동작하는 중입니다. (따로 id 시퀀스가 증가가 잘되는 것을 확인한게 웹페이지에서 넣고, 테스트로 돌리고, 다시 웹페이지에서 넣었을시, id가 8,10이 뜨는걸로 확인했습니다.) 어떻게 수정하면 될까요..ㅎ?

실전! 스프링 부트와 JPA 활용2 - API 개발과 성능 최적화

하이버네이트 모듈이 기본상태일때 orderItem을 DB에서 자꾸 쿼리하는게 로그상에 보여서 질문드리는데요 이 상태에서 Order엔티티에 "orderItems" 는 1대다 관계로 묶여있어서 당연히 기본이 lazy로딩이라서 orderItems에 접근하지 않는한 DB에서 쿼리하지 않을줄 알았는데 쿼리가 나가더라구요 ..? 왜 그런걸까요 ..?? 제가 배운 내용으로는 이해가 가지 않아서 ㅠㅠ

@Transacional의 범위에 대해서 궁금한 점이 하나 있습니다!

해결됨

실전! 스프링 부트와 JPA 활용1 - 웹 애플리케이션 개발

안녕하세요 강사님. 항상 훌륭한 강의 감사드립니다. 스프링 MVC 1, 2편에서 사용했던 프로젝트에 JPA를 적용시키는 도중 궁금한점이 하나 생겨서 질문드립니다. TestInitData 클래스에 @PostConstruct로 데이터베이스에 초기 데이터들을 넣어두려고 합니다. package com.myservice.web.test ; import com.myservice.domain.item.Item ; import com.myservice.domain.item.ItemRepository ; import com.myservice.domain.member.Grade ; import com.myservice.domain.member.Member ; import com.myservice.domain.member.MemberRepository ; import com.myservice.domain.member.MemberService ; import lombok. RequiredArgsConstructor ; import lombok.extern.slf4j. Slf4j ; import org.springframework.stereotype. Component ; import org.springframework.transaction.annotation. Transactional ; import javax.annotation. PostConstruct ; @Slf4j @Component @RequiredArgsConstructor @Transactional public class TestDataInit { private final ItemRepository itemRepository ; private final MemberService memberService ; private final MemberRepository memberRepository ; /** * 테스트용 데이터 추가 */ @PostConstruct public void init () { itemRepository .save( new Item( "itemA" , 10000 , 10 )) ; itemRepository .save( new Item( "itemB" , 20000 , 20 )) ; itemRepository .save( new Item( "itemC" , 15000 , 15 )) ; Member member1 = new Member() ; member1.setLoginId( "manager" ) ; member1.setPassword( "manager" ) ; member1.setUsername( " 최한슬 " ) ; member1.setGrade(Grade. MANAGER ) ; Member member2 = new Member() ; member2.setLoginId( "user" ) ; member2.setPassword( "user" ) ; member2.setUsername( "USER" ) ; // 바로 memberRepository.save 로 접근하면 현재 스레드에서 사용할 수 있는 EntityManager 가 없다고 오류 발생 memberRepository .save(member1) ; memberRepository .save(member2) ; //memberService.save -> memberRepository.save 로 접근하면 정상적으로 작동 memberService .save(member1) ; memberService .save(member2) ; } } 또한, memberRepository와 memberService는 다음과 같습니다. [memberRepository] package com.myservice.domain.member ; import org.springframework.stereotype. Repository ; import java.util.List ; import java.util.Optional ; @Repository public interface MemberRepository { Long save (Member member) ; Optional<Member> findById (Long id) ; Optional<Member> findByLoginId (String loginId) ; List<Member> findAll () ; } package com.myservice.domain.member ; import lombok. RequiredArgsConstructor ; import org.springframework.context.annotation. Primary ; import org.springframework.stereotype. Repository ; import javax.persistence.EntityManager ; import java.util.List ; import java.util.Optional ; @Repository @RequiredArgsConstructor @Primary public class JpaMemberRepository implements MemberRepository { private final EntityManager em ; @Override public Long save (Member member) { em .persist(member) ; return member.getId() ; } @Override public Optional<Member> findById (Long id) { Member member = em .find(Member. class, id) ; return Optional. ofNullable (member) ; } @Override public Optional<Member> findByLoginId (String loginId) { Member member = em .createQuery( "select m from Member m where m.loginId = :loginId" , Member. class ) .setParameter( "loginId" , loginId) .getResultStream() .findAny() .orElse( null ) ; return Optional. ofNullable (member) ; } @Override public List<Member> findAll () { return em .createQuery( "select m from Member m" , Member. class ) .getResultList() ; } } [memberService] package com.myservice.domain.member ; import lombok. RequiredArgsConstructor ; import org.springframework.stereotype. Service ; import org.springframework.transaction.annotation. Transactional ; @Service @Transactional @RequiredArgsConstructor public class MemberService { private final MemberRepository memberRepository ; public void save (Member member) { memberRepository .save(member) ; } } 현재 MemberService에는 @Transactional이 걸려있고, memberRepository에는 @Transactional 걸려있지 않습니다. 궁금한점은 TestDataInit 클래스의 init() 메서드에서 바로 memberRepository로 접근하게되면 사용할 수 있는 EntityManager가 없다고 나오며, memberService->memberRepository로 접근하게 되면 정상적으로 처리되는 것을 확인하였습니다. 두 방식 모두 결국 memberRepository를 통해 save를 수행하게 되는데 바로 memberRepository의 접근은 오류가 발생하고 memberService를 통한 접근은 정상적으로 처리되는 이유를 모르겠습니다.
