안녕하세요, 강사님. 컨트롤러 코드 관련 질문입니다. 작성한 코드는 컨트롤러의 메소드 반환 타입을 void로 해서 아무것도 반환하지 않는데요, 만약 postmapping 관련 메소드 작성 시, 작성한 게시글의 id값을 반환해주는 코드와 큰 차이가 있을까요? 그리고 찾아보던 중, ResponseEntity를 사용해서 반환해주는 메소드를 보았는데, 메소드의 반환 타입에 따라 기능에 큰 차이가 있는지, 아니면 API 명세의 차이만 있고 기능에는 크게 차이가 없는지 궁금합니다!

안녕하세요 oracle db에서 서브쿼리 안에서 groupby를 했을떄 ORA-02287 sequence number not allowed here 오류가 나옵니다. 검색해보니 SEQUENCE를 사용할 수 없는 경우는 다음과 같다. SELECT 문장의 경우에서 1. WHERE 절 안에서 2. GROUP BY나 ORDER BY 절에서 3. DISTINCT 절에서 4. UNION 이나 INTERSECT 나 MINUS 와 함께 사용 할때 5. 서브 쿼리 안에서 라고 하는데 제 경우에는 이 group by를 하고싶으면 어떻게 할수있나요? 감사합니다. Integer sucessCount =0, JPQLQuery<Tuple> subQuery = JPAExpressions.select( log.name, log.content, new CaseBuilder() .when(log.statusCode.eq("0") .then(sucessCount+1) .otherwise(successCount), client.id ) .from(log) .leftJoin(client) .on(client.name.eq(log.name)) //이 group by가 문제 .groupBy(log.name, log.content, client.id); queryFactory.insert(stats) .columns( stats.name, stats.content, stats.successCount, stats.clientId ) .select(subQuery) .execute();

전 윈도우 기반에서 선생님 온라인 강의 청취하고 있습니다. git besh에서 sdkman으로 springboot 설치해서 터미널 상에서 spring 서버로 테스트까진 확인하고 터미널에서 인텔리J로 접속이 되지않아 그냥 인텔리J에서 프로젝트 오픈하여 수업을 따라가고 있었는데 인텔리J와 스프링부트 연동하는 방법을 몰라서 질문 남깁니다.

@ManyToOne @JoinColumn(name = "parent_id") private Category parent; @OneToMany(mappedBy = "parent") private List<Category> child = new ArrayList<>(); 부모와 자식을 이렇게 설정해준다는데, 부모를 Many To One 자식을 One To Many 로 해주는게 이해가 안갑니다. 왜 이렇게 연관관계를 설정해 줘야 하는건가요?
public class student { public int score; public int getScore() { return this.score; } } 위와 같은 코드가 있고 연관관계 매핑이 되어있어 현재 프록시 상태라고 가정했을 때 점수를 얻기 위해 student.score를 사용 하면 영속성 컨텍스트로부터 초기화를 받지 못하고, student.getScoret()를 하면 초기화를 받는 건가요 ? 만약 프로퍼티 접근을 사용했을 때 초기화를 받지 모한다면 studnet.score 안에는 무슨 값이 들어있게 되는 건가요 ?

실전! 코틀린과 스프링 부트로 도서관리 애플리케이션 개발하기 (Java 프로젝트 리팩토링)
- 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. 자바 스프링에서는 테스트용 생성자 메서드가 있어도, 매번 일일히 null을 넣어준다거나 하는 문제점들이 있어서 결국 Builder를 사용했었는데 코틀린에서는 롬복 Builder가 지원되지 않는다고 해서 엄청 고민 중이였습니다 근데 이번 강의 보니까 그냥 온전한 객체 만들어주는 팩터리 메서드 하나 만들어놓고 테스트용으로 필요한 인자 값들만 설정해주면 되는 거였군요 진짜 미쳤다.. 갓틀린.. 잘 배워갑니다..
@PostMapping("/items/{id}/edit") public String updateItem(@PathVariable Long id, @ModelAttribute Item item) { Item findItem = itemService.findById(item.getId()); //더티 체킹 findItem.setId(item.getId()); findItem.setName(item.getName()); findItem.setPrice(item.getPrice()); findItem.setStockQuantity(item.getStockQuantity()); findItem.setAuthor(item.getAuthor()); findItem.setIsbn(item.getIsbn()); return "redirect:/items"; } 강의를 보지 않고 스스로 코드를 짜보고 있는데 이렇게 하니까 수정내역이 반영 되지 않더라구요 스스로 생각해봤을 때는 다음 2가지 이유 중 하나일 것 같은데 이유가 이유가 무엇인가요 ㅠㅠ? findItem은 영속성 컨텍스트가 관리하지 않는 객체가 된 것이다. 따라서 더티체킹이 되지 않는다. 영속성 컨텍스트가 관리하는 엔티티는 맞지만 Controller에는 트랜잭션이 없어서 반영이 안되는 것이다.
안녕하세요 토비님. 우선, 감동으로 청강을 이어갈 기회를 얻게되어 참 감사드립니다. 아래는 섹션8 - DataSource 자동 구성 클래스 파트의 @Bean 메서드 등록과정에 생긴 문제입니다. 의문점은 메서드 선언 순서에 영향을 받는다는것을 알게되서 다음처럼 2번의 테스트를 진행했습니다. @Bean 메서드 선언순서 에 따른 등록 테스트 simple , hikari hikari, simple 1 결과: simple 이 등록됨 /* DataSourceConfig.java */ @Bean @ConditionalOnMissingBean public DataSource simpleDriverDataSource() { ... } @Bean @ConditionalOnMissingBean @ConditionalMyOnClass("com.zaxxer.hikari.HikariDataSource") public DataSource hikariDataSource() { ... } hikari 에 `@ConditionalMyOnClass` 가 있기때문에 등록될 것으로 예상했지만, simple 이 등록되었습니다. 2 결과: hikari 가 등록됨 @Bean @... public DataSource hikariDataSource() { ... } @Bean @... public DataSource simpleDriverDataSource() { ... } 기묘하게도 @Bean 메서드 선언순서를 바꾸니 Hikari 빈이 등록되었습니다. 이상하다 싶어, @Primary 와 @Order(n) 을 주고 다시 테스트 해봤지만, 영향을 주지 않았습니다. 질문: 위와 같이 @Bean 메서드 순서에 영향을 받는 이유가 궁금합니다. 이 결과로 @ConditionalOnClass 의 인식되는 FQCN 의 조건을 바꿔보기도 하고, 위치도 바꿔봤는데, 이렇다할 동작방식을 파악하기 힘들었습니다. 그리고 @Primay 나 @Order 를 붙여가며 추가적인 등록순서에 대해 테스트를 진행했으나, 이것들 역시 영향을 주지 않았습니다. 여러 곳에서 알아본 바, @Bean 메서드는 등록순서에 영향을 주지 않는것으로 알고있었는데, 이런 경우에는 어떤 매커니즘이 동작하는지가 궁금합니다. 이 결과를 보고 생각에 혼란이 와서 질문을 드리게 되었어요. 혹시 제가 놓친것이 있다면 조언을 부탁드려도 되겠습니까? 읽어주셔서 감사합니다☺️
@EntityGraph(attributePaths = "team") List<Member> findEntityGraphByUsername(@Param("username")String username); 이번 강의를 복습하다 보니까 강사님께서 @Param을 사용하셨더라구요.(강의 20:59) findByAge(), findOptionalByUsername()과 같은 메소드는 @Param 애노테이션 없이도 잘 동작 했는데 따로 특별한 이유가 있는 것일까요?
