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

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.

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.

※ 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?

thymeleaf, cannot resolve vars 에러 문제

이런식으로 에러가 떠서 구글링을 해보니 다양한 해결책이 있긴한데 그것이 옳은 방식으로 해결되는 것인지 모르겠습니다 <html xmlns:th="http://www.thymeleaf.org"> 여기에서 www를 삭제하면 th: 라인이 전부 초록색으로 변하면서 에러는 해결되기는 하더라고요 다른 해결 방식이 있을까요?

데이터베이스 연동관련 문의

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?

프록시 관련해서 질문 있습니다.

안녕하세요! 강사님께서 em.clear를 한순간 끈건 아니지만 영속석 컨텍스트안에 완전히 다 지우고 새로 만든거라고 하셨는데 refMember.getUserName();을 한 순간에 DB를 조회해서 쿼리가 나가서 해당 클래스가 영속성 컨텍스안에 들어가는걸로 알고 있습니다. 근데 아직 DB 조회를 하기전( refMember.getUsername()을 하기전 )이라 영속성 컨텍스트안에 해당 클래스가 없는거 아닌가요? 항상 강의 잘보고있습니다 . 감사합니다!!

repository은 트랜젝션이 기본인가요?

예전에는 service단에서 trasaction을 걸어서 했었는데 repository에 기본적으로 @trasantional이 적용되어있나요?? 그렇기 때문에 db에서 쿼리를 해올수잇는건지 궁금합니다 ㅎㅎ 추가적으로 repository에 transation이 걸려있다면 왜 service 클래스에 이중으로 @trasational 어노테이션을 거는건가요?

Hibernate5Module가 기본상태일때

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!

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@Transactionalpublic 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.save로 접근하면 현재 스레드에서 사용할 수 있는 EntityManager가 없다고 오류 발생 memberRepository.save(member1); memberRepository.save(member2); //memberService.save -> memberRepository.save로 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;@Repositorypublic 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@Primarypublic 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@RequiredArgsConstructorpublic 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.

질문있습니다.

안녕하세요 insert 벌크 쿼리에 관해 질문있습니다. 강의에서 말씀해주신 대로 해보니 delete와 update의 경우 한번에 처리되는 것을 확인할 수 있었습니다. 문제는 Insert 였습니다. 저는 MySQL 를 사용하면서 IDENTITY 전략을 사용해왔었는데 MySQL의 경우 벌크 INSERT 쿼리를 날리기 위해서는 찾아보니 Batch Insert를 사용하기 위해서는 IDENTITY 전략이 아니라 TABLE 전략을 사용해야 한다고 하더라구요. 제가 궁금한 점은 아래와 같습니다. 1. 다른 ENTITY들은 IDENTITY 전략을 사용하고 Batch Insert가 필요한 특정 ENTITY만 TABLE 전략으로 변경해도 괜찮을까요? 2. 실무에서는 INSERT 쿼리를 한 번에 날리기 위해서는 어떤 방식을 사용하나요?? 감사합니다 :) 2.

양방향 매핑이 언제 필요한지 여쭤보고 싶습니다.

선생님 안녕하세요! 매번 정말 좋은 강의 감사드립니다ㅋㅋㅋㅋ 저 진짜 웹 하나도 모르는 생짜 초보인데, 갑자기 자바 스프링 실무에 투입되어서 넘 힘들었거든요ㅠㅠ 바로 선생님 강의 패키지로 싹 다 결제하고, 하나씩 들으면서 감을 잡고 있습니다. 제 구세주십니다. 감사합니다!! (다음달 월급 들어오면 선생님께 다 갈 예정입니다..?!ㅎㅎㅎ) 최근에 JPA Mapping 관련해서 공부하고 또 실무에 적용해 보고 있는데요, 현재 제가 하는 프로젝트에서는 음식 재료 바구니 기능을 구현해야 합니다. 요게 유저 - 대바구니 - 소바구니 - 음식 재료로 이어지는 계층적 구조이고, 유저 하나가 여러 대바구니, 대바구니 하나가 여러 개의 소바구니, 소바구니 하나가 여러 개의 음식 재료를 포함하는 구조입니다. 각 자식들은 하나의 부모에만 속하게 되어 있구요. 쌤 강의 듣고 일단은 ManyToOne 단방향 매핑으로 각각을 1:N으로 걸어줬는데요. 특정 대바구니 id 아래에 있는 소바구니 (혹은 그 소바구니 아래에 있는 음식 재료까지)를 조회하거나, 특정 소바구니 id 아래에 있는 음식 재료들을 조회하거나 하는 쿼리가 가끔 필요한 상황입니다. 또 대바구니 하나를 삭제하면 그 밑에 소바구니는 싹 다 지워지고, 소바구니 하나를 지우면 그 바구니에 음식 재료들은 싹 다 지워져야 하는 상황이구요. 즉 DELETE시 CASCADE + 가끔 부모 아래에 있는 자식을 부모 id로 조회하는게 필요한 상황입니다. 요럴때 양방향 매핑이 필요할까요?! 현재 고민하고 있는 옵션은 - 단방향 매핑으로 계속 가되 ON DELETE CASCADE를 DB TABLE에 걸어줘서 부모 삭제시 자식도 삭제되도록 만든다. - 아니면 양방향 매핑으로 해주고 mappedBy 있는쪽에 CASCADE.ALL, orphanRemoval 걸어준다. 인데요, 1) 성능이 단방향, 양방향 매핑에서 차이가 많이 나는지 궁금합니다. 2) 그냥 단방향 매핑으로 모든 거 처리하고, 필요할때만 sql join query 날려서 join해서 불러오면 되는거 아냐? 라는 생각도 드는데요.. 그리고 추가 질문으로, 언제 양방향 매핑을 사용하는게 좋은지 잘 모르겠습니다. 양쪽에서 참조할 일이 있을 때라고 강의에서는 말씀해 주셨는데 잘 안 와 닿더라구요. 혹시 실무 예시를 좀 들어 주실 수 있으실까요? 감사합니당!!!

hibernate.dialect 오라클 변경시 문의드려요.

시점 : 26:25 org.hibernate.dialect.Oracle12cDialect 로 변경시 쿼리가 rownum계열이 아닌 Hibernate: /* select m from Member as m */ select member0_.id as id1_0_, member0_.name as name2_0_ from Member member0_ fetch first ? rows only 와 같이 나오는데 왜그런지 궁금합니다.
