public void addOrderItem(OrderItem orderItem) { orderItems.add(orderItem); orderItem.setOrder(this); }강사님은 양방향 연결을 해서 연관관계 매서드 작성하셨는데 단방향 연결해서 orderItem에만 @ManyToOne 한 경우에는 어떻게 하나요? 아니면 다대다라서 중간테이블쓴경우에는 무조건 양방향 설정을 해야하나요?

안녕하세요 궁금한 것이 있습니다.JPA에서 @OneToMany를 통한 단방향 연관관계에서 문제로 지적되는 것이 Many쪽의 FK를 update. 하기 위한 추가적인 쿼리 문제인데요. (물론 이것만이 @OneToMany 단방향의 문제는 아닙니다만)이 문제는 @JoinColumn(nullable = false, updatable = false)이라는 설정을 통해 해결할 수 있는 것으로 알고 있습니다.이러면 One을 먼저 insert한 후, Many를 insert할 때 One의 PK를 바탕으로 추가적인 업데이트 쿼리 없이 바로 insert를 해주는걸로 알고 있습니다.근데 "대체 JPA는 왜 이렇게 설계한걸까?" 라는 의문이 듭니다.물론 앞서 말씀드린 방법은 FK가 not nullable이여야하고, FK가 변경되면 안된다는 제약 조건이 들어가야하기 때문에, 모든 상황에서 공통적으로 적용되는 방법은 아닙니다만, 차라리 이런 설정을 default로 하는게 이해하기 더 쉬운 방법아닌가? 라는 생각이 들어서요.FK가 nullable하고, 또 변경될 수 있는 상황은 상대적으로 적은데다가, insert한 컬럼에 FK를 추가해주기 위해 update 쿼리가 나가게 되는 로직은 성능적으로도(드라마틱하진 않지만) 좋지 않고, hibernate를 처음 사용하는 사람은 "대체 왜 이렇게 쿼리가 나가지?"라는 식으로 이해하기 어렵다고 판단이 들거든요.사실 이게 프로그래밍 하는데 중요한 지식은 아니지만.. 그냥 순전히 호기심으로 궁금합니다.

[질문 템플릿]1. 강의 내용과 관련된 질문인가요? (예)2. 인프런의 질문 게시판과 자주 하는 질문에 없는 내용인가요? (예)3. 질문 잘하기 메뉴얼을 읽어보셨나요? (예)[질문 내용]여기에 질문 내용을 남겨주세요.SimpleJpaRepository가 처음에 생성될 때 entitymanager를 의존성 주입을 받아서 초기화가 됩니다.문제는 전에 강의에서 entitymanager는 트랜색션 하나당 하나를 생성해야 한다고 했던 것이 생각납니다. 문제는 이렇게 처음 초기화할 때 entitymanager를 주입받게되면 한 entitymanager를 스프링 프로그램이 끝날 때 까지 사용하게 되는데 문제가 없는건가요?https://jiwondev.tistory.com/225이런식으로 트랜색션이 끝나고 연결이 끝나도 entitymanager를 유지하면 문제가 생기지 않을까 생각되어 질문드립니다.

자바 17 사용하는데 아래와 같은 오류가 납니다.

안녕하세요! 스프링 데이터 JPA를 상속받은 리포지토리를 통해 crud 구현 연습을 하고 있었습니다. 게시판 유저와 유저가 작성한 글을 각각 User, Article 엔티티로 표현했습니다.User의 경우 모든 기능이 정상적으로 작동됩니다.그런데 Article은 삭제가 이루어지지 않는 현상이 발생하고 있습니다.그렇다고 중간에 예외가 발생하는 것도 아니고, 삭제시에는 삭제한 엔티티의 정보를 반환하게끔 설계했는데 멀쩡히 반환이 잘되고 DB에서도 삭제되지 않았습니다.package com.crud.controller.article; import com.crud.constant.MessageConst; import com.crud.dto.Result; import com.crud.entity.User; import com.crud.service.ArticleService; import com.crud.service.UserService; import com.crud.utils.ResultUtils; import lombok.RequiredArgsConstructor; import org.springframework.data.domain.Page; import org.springframework.data.domain.Pageable; import org.springframework.data.web.PageableDefault; import org.springframework.http.ResponseEntity; import org.springframework.validation.annotation.Validated; import org.springframework.web.bind.annotation.*; @RestController @RequestMapping("/articles") @RequiredArgsConstructor public class ArticleController { private final ArticleService articleService; private final UserService userService; private final MessageConst messageConst; @GetMapping public ResponseEntity<Result<Page<ArticleDTO>>> articles(@ModelAttribute ArticleSearchCond articleSearchCond, @PageableDefault Pageable pageable) { Page<ArticleDTO> page = articleService.findAll(articleSearchCond, pageable); return ResponseEntity.ok().body(ResultUtils.success(page, messageConst.successSearch())); } @GetMapping("/{id}") public ResponseEntity<Result<ArticleDTO>> article(@PathVariable Long id) { ArticleDTO foundArticle = new ArticleDTO(articleService.findById(id)); return ResponseEntity.ok().body(ResultUtils.success(foundArticle, messageConst.successSearch())); } @PostMapping("/save") public ResponseEntity<Result<ArticleDTO>> save(@RequestBody @Validated ArticleSaveDTO saveDTO) { User user = userService.findById(saveDTO.getUserId()); ArticleDTO articleDTO = articleService.save(saveDTO, user); return ResponseEntity.ok().body(ResultUtils.success(articleDTO, messageConst.successSave())); } @PatchMapping("/{id}") public ResponseEntity<Result<ArticleDTO>> update(@PathVariable Long id, @RequestBody ArticleUpdateDTO updateDTO) { ArticleDTO updatedArticle = articleService.update(id, updateDTO); return ResponseEntity.ok().body(ResultUtils.success(updatedArticle, messageConst.successUpdate())); } // 삭제 메서드 호출입니다!!!!!! @DeleteMapping("/{id}") public ResponseEntity<Result<ArticleDTO>> delete(@PathVariable Long id) { ArticleDTO deletedArticle = articleService.delete(id); return ResponseEntity.ok().body(ResultUtils.success(deletedArticle, messageConst.successDelete())); } } package com.crud.service; import com.crud.controller.article.ArticleDTO; import com.crud.controller.article.ArticleSaveDTO; import com.crud.controller.article.ArticleSearchCond; import com.crud.controller.article.ArticleUpdateDTO; import com.crud.entity.Article; import com.crud.entity.User; import com.crud.exception.NoSuchDataException; import com.crud.repository.article.ArticleRepository; import lombok.RequiredArgsConstructor; import lombok.extern.slf4j.Slf4j; import org.springframework.data.domain.Page; import org.springframework.data.domain.Pageable; import org.springframework.stereotype.Service; import org.springframework.transaction.annotation.Transactional; @Slf4j @Service @Transactional @RequiredArgsConstructor public class ArticleService { private final ArticleRepository articleRepository; @Transactional(readOnly = true) public Page<ArticleDTO> findAll(ArticleSearchCond articleSearchCond, Pageable pageable) { return articleRepository.findAll(articleSearchCond, pageable); } @Transactional(readOnly = true) public Article findById(Long id) { return articleRepository.findById(id).orElseThrow(NoSuchDataException::new); } public ArticleDTO save(ArticleSaveDTO saveDTO, User user) { Article article = Article.createArticle(saveDTO, user); Article savedArticle = articleRepository.save(article); return new ArticleDTO(savedArticle); } public ArticleDTO update(Long id, ArticleUpdateDTO updateDTO) { Article article = findById(id); article.update(updateDTO); return new ArticleDTO(article); } // 삭제 메서드입니다!!!!! public ArticleDTO delete(Long id) { // articleRepository.deleteById(id); Article article = findById(id); articleRepository.delete(article); return new ArticleDTO(article); } }컨트롤러가 userService, articleService를 둘다 주입받고 있어서 트랜잭션이 꼬였나하고 userService를 지워보았는데 여전히 삭제는 안되었습니다. 그런데 만약 articleService.delete()의 반환타입을 void로 하여 아무것도 반환안하고(컨트롤러가 반환하는 api의 내용물도 그냥 null로 설정했습니다) 주석처리한 deleteById(id)를 사용해서 id로 바로 지우면 DB에서의 삭제가 이루어졌습니다. 이유를 계속 생각해보고 이거저거 건드려보고있긴한데, 아직까지는 도저히 모르겠습니다.. 리포지토리는 동적검색메서드만 따로 추가되었지, 삭제 메서드는 스프링 데이터 JPA의 delete를 그대로 가져다 쓴것입니다. 혹시 추가적인 코드가 필요하다면 말씀해주세요!

안녕하세요!! 강의 중 ApiResponse라는 제네릭 클래스를 만들 때에는 Builder를 사용하지 않으셨는데, 제네릭 클래스여서 사용하지 않은 건가요??그리고 혹시 Builder패턴을 사용을 하지 않았으면 하는 부분들이 있을까요?항상 친절하게 답해주셔서 감사합니다!!

학습 관련 질문을 남겨주세요. 어떤 부분이 고민인지, 무엇이 문제인지 상세히 작성하면 더 좋아요!먼저 유사한 질문이 있었는지 검색해 보세요.서로 예의를 지키며 존중하는 문화를 만들어가요.강사님은 현업에서 TDD를 사용해서 개발하시는지 궁금합니다!

=========================================[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]트랜잭션이 실제 적용되고 있는지 확인하는 방법에서 TxApplyBasicTest 코드 짤때요 BasicService 프록시 객체가 스프링빈으로 자동등록되는데 왜 굳이 @TestConfiguration 에서 BasicService를 수동으로 빈 등록을 하는건가요?? 안해도 되는거 아닌가요?어차피 프록시 객체가 등록되어있어서 @Autowired로 의존관계 주입받을 수 있지 않나요??

연관 데이터를 불러와야 하는 상황에서 지연 로딩 전략을 취하고 페치조인을 사용하는 것이 N+1 문제를 해결하는 방법이자, 성능 최적화의 방법이라고 알고 있습니다. 그런데 JPA에서 엔티티 그래프를 사용해도 N+1 문제를 해결할 수 있지 않나요? 사용 방법도 더 편리하고 좋은 것 같은데, 엔티티 그래프를 사용하지 않는 이유가 있나요?

TxBasicTest에서proxyCheck에서 테스트를 돌리면 에러가 나옵니다기대값은 true인데 false가 나온다고합니다. package hello.springtx.apply; import lombok.extern.slf4j.Slf4j; import org.assertj.core.api.Assertions; import org.junit.jupiter.api.Test; import org.springframework.aop.support.AopUtils; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.boot.test.context.SpringBootTest; import org.springframework.boot.test.context.TestConfiguration; import org.springframework.context.annotation.Bean; import org.springframework.transaction.support.TransactionSynchronizationManager; import static org.assertj.core.api.Assertions.assertThat; @Slf4j @SpringBootTest public class TxBasicTest { @Autowired BasicService basicService; @Test void proxyCheck(){ log.info("aop class={}", basicService.getClass()); assertThat(AopUtils.isAopProxy(basicService)).isTrue(); } @TestConfiguration static class TxApplyBasicConfig{ @Bean BasicService basicService(){ return new BasicService(); } } @Slf4j static class BasicService{ public void tx(){ log.info("call tx"); boolean txActive = TransactionSynchronizationManager.isActualTransactionActive(); log.info("tx active={}", txActive); } public void nonTx(){ log.info("call nonTx"); boolean txActive = TransactionSynchronizationManager.isActualTransactionActive(); log.info("nonTx active={}", txActive); } } }

구분에 대해 명확히 이해가 되지 않는데요,SOA 경우도 서비스 단위 개발이고 Microservice도 그렇지 않나요? 그 규모의 차이가 둘을 구분 짓는 건가요?ex) SOA의 서비스 단위가 숙박 예약 기능이라고 하면Microservice는 숙박조회, 결제 ... 으로 더 세분화 그리고 SOA에서 직접 서비스간에 데이터 교환을 하는 것에서 발생하는 의존 문제로 인해 ESB를 도입했다고 봤는데요, Microservice에서는 API를 통해 서비스 간 통신 시 이런 의존문제가 없을 수 있는건가요? 뭔가 구체적인 예시로 비교해주시면 감사하겠습니다.
