실전! 스프링 부트와 JPA 활용1 - 웹 애플리케이션 개발
p6spy releases를 확인해보면 1.9.0부터 Spring boot 3을 지원한다고 되어있고 테스트시 로그가 안뜹니다. 다른 질문에서보니 해당 버전이 메이븐에서만 지원되어서 그런 듯 합니다. 그래서 바로 아래 버전인 1.8.1을 사용해서 정상적으로 로그가 뜨는 것을 확인했습니다. 그래서 앞으로 최신 버전으로 했을때 안뜬다면 버전을 내려보시면 좋을 것 같습니다.

bottomnavigatorbar만 사용할때와 bottomnavigatorbar와 tabbarview를 사용하는데 physics: NeverScrollableScrollPhysics() 이 조건을 추가하는거랑 어차피 bottomnavigatorbar로만 화면 이동이 가능한데 두개의 차이점이 무엇인지 궁금합니다!

(예/아니오) [질문 내용] 안녕하세요. 카운트 쿼리 분리 부분을 듣는 도중에 카운트 쿼리에 LEFT JOIN이 사용되는 결과를 확인하기 위해 다음처럼 코드를 작성하였습니다. public interface MemberRepository extends JpaRepository<Member, Long> { @Query(value = "select m from Member m left join m.team t") Page<Member> findByAge(int age, Pageable pageable); ... } @Test public void paging() throws Exception { //given memberRepository.save(new Member("member1", 10)); memberRepository.save(new Member("member2", 10)); memberRepository.save(new Member("member3", 10)); memberRepository.save(new Member("member4", 10)); memberRepository.save(new Member("member5", 10)); //when PageRequest pageRequest = PageRequest.of(0, 3, Sort.by(Sort.Direction.ASC, "username")); Page<Member> page = memberRepository.findByAge(10, pageRequest); //then List<Member> content = page.getContent(); assertThat(content.size()).isEqualTo(3); assertThat(page.getTotalElements()).isEqualTo(5); assertThat(page.getNumber()).isEqualTo(0); assertThat(page.getTotalPages()).isEqualTo(2); assertThat(page.isFirst()).isTrue(); assertThat(page.hasNext()).isTrue(); } 그런데 결과는 강의와는 달리 카운트 쿼리에 LEFT JOIN 이 사용되지 않았고, 심지어 JPQL select m from Member m left join m.team t 을 @Query에 작성했음에도 조회 쿼리도 LEFT JOIN을 사용하지 않은 것을 확인했습니다. 이후 스프링 부트 3 이하 버전에서 동일한 코드로 실행해보니 강의와 동일한 결과를 얻을 수 있었습니다. 스프링 부트 3 부터 적용된 스프링 데이터 JPA 에서는 이러한 부분의 최적화를 자동으로 제공하는 것일까요?

안녕하세요. 강사님 페이스북 sns 로그인 기능을 추가하여 앱 사용하고 있었습니다. 현재 안드로이드는 페이스북 로그인 사용 가능하도록, ios는 로그인 아이콘을 숨김 처리하여 사용 하지 못하게 막아 놓은 상태입니다. 이런 sns 로그인 기능의 경우 안드로이드, ios 동일하게 사용하도록 아이콘을 오픈해야하는지와 플랫폼 정책이 있는지 궁금합니다. 감사합니다.

typedef ColorIdSetter = void Function(int id); 정의를 해서 ColorIdSetter는 int id값을 받는 함수라고 이해했습니다. 그리고 아래 코드에서 색상을 누르면 해당 색상의 id 값을 넘겨주는 것까지 이해했습니다 GestureDetector( onTap: () { colorIdSetter(e.id); }, 잘 이해가 되지 않는 부분은, final ColorIdSetter colorIdSetter; 위 코드 처럼 외부에서 받게 되면 아래 코드를 입력할때 (int id) 값을 어떻게 받아 와서 selectedColorId에 id를 넘겨줄 수가 있는 건지 잘 이해가 되지 않습니다. colorIdSetter: (int id) { setState(() { selectedColorId = id; }); }, onTap 메소드 안에서 colorIdSetter( e.id )로 넣어준 id 값이 colorIdSetter: (int id) {} 의 id로 들어가게 되는건가요? 어떻게 그렇게 되는지 몇번을 봐도 이해가 되지 않아서 질문 남깁니다 ㅠㅠㅠ 코드를 계속 보고 있으니까 점점 미궁으로 들어가는 거 같네요,,
