안녕하세요 회원 서비스 테스트 강의 듣다가 이해 안가는 부분이 있어서 질문드립니다12:11 에서MemoryMemberRepository memberRepository = new MemoryMemberReposiory(); 이 코드를 왜 작성해야하는지 이해가 안갑니다. clearStore()를 할거면 그냥 위에 적힌 memberService.memberRepository.clearStore(); 로 해도 같은 기능을 하는 코드가 아닌가요? 그리고 memberService.memberRepository를 사용하면 하나의 회원repository instance만 사용하므로 회원 서비스 코드를public class MemberService{ private final MemberRepository memberRepository; public MemberService(MemberRepository memberRepository){ this.memberRepository = memberRepository; } }위와 같이 작성하지 않아도 되는거 아닌지 궁금합니다

안녕하세요. 좋은 강의를 감사히 듣고 있는 학생입니다.다름이 아니라 이번에 실무에 가까운 프로젝트를 하면서 Common Error Page (Custom Error Page) 가 필요하다는 얘기를 듣게 되었습니다. 어떤 에러가 발생하는 경우에 기본적인 에러 화면이 아닌 디자인 된 에러 페이지로 항상 가야한다는 요청 사항인데 이건 static 인가요 template 인가요? 어떻게 구현하나요?

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!

- 학습 관련 질문을 남겨주세요. 상세히 작성하면 더 좋아요! - 먼저 유사한 질문이 있었는지 검색해보세요. - 서로 예의를 지키며 존중하는 문화를 만들어가요. - 잠깐! 인프런 서비스 운영 관련 문의는 1:1 문의하기를 이용해주세요. 안녕하세요! XSS관련하여서 JSON데이터를 암호화하는것을 수강하였습니다. 이 데이터를 react로 보낸다고 하면 react는 이를 어떻게 decode하나요?

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?
