(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?

기존에는 SecurityConfig 클래스의SecurityFilterChain에서 아래의 코드가로그인 실패 시 응답을 처리하는 주체였습니다. http.exceptionHandling() // 인증 예외 설정 .authenticationEntryPoint((request, response, authenticationException)->{ // 예외 가로채기\ CustomResponseUtil.fail(response, "로그인을 진행해주세요", HttpStatus.UNAUTHORIZED); });그러다 JwtAuthenticationFilter를 만들면서attemptAuthentication() 매서드가 실패 시 아래의unsuccessfulAuthentication()가 실행되게끔 했구요.@Override protected void unsuccessfulAuthentication(HttpServletRequest request, HttpServletResponse response, AuthenticationException failed) throws IOException, ServletException { CustomResponseUtil.fail(response, "로그인 실패", HttpStatus.UNAUTHORIZED); } 그래서 헷갈려서 실험해보니 기존의 SecurityFilterChain의 것은 주석처리해도 아무런상관이 없고, unsuccessfulAuthentication()가 동작하더라구요.이 두 코드의 차이는 정확히 어떤 것일까요?

JPA에서 컬렉션 조회와 페이징을 함께 사용하려면ToOne (OneToMany, OneToOne) 관계를 모두 페치 조인하고, 지연 로딩 성능 최적화를 위해 hibernate.default_batch_fetch_size 옵션을 적용해야 한다.라고 배웠었는데 이 내용이 Spring Data JPA에서도 컬렉션을 조회하면서 페이징 관련된 Pageable, Page 등을 사용하기 위해서는default_batch_fetch_size 를 적용해줘야 하는 거죠??
