앞선 강의들에서 driverManager는 라이브러리에 등록된 DB 드라이버들을 관리하고 커넥션을 획득하는 기능을 제공한다고 배웠습니다.하지만 여러 요청이 동시에 왔을 때 DriverManager는 커넥션이 하나 뿐이라 여러 요청을 병렬처리를 할 수 없다는 단점이 있어 커넥션 풀 이라는 개념을 도입하여 여러 요청을 풀 내의 여러개의 커넥션을 통해 병렬 처리가 가능하도록 하는 것이고, 이러한 커넥션을 획득하는 방법이 DriverManager, Hikari, DBCP2 등 여러 커넥션 획득 방법이 존재하기 때문에 이들을 추상화해둔 것이 DataSource interface이고, DataSource 구현체로 DriverManager를 통한 커넥션 획득 방법은 DriverManagerDataSource, Hikari를 통한 커넥션 획득 방법은 HikariDataSource이다.제가 이해한 것은 이정도 인데 맞는지 모르겠습니다..

안녕하세요,김영한 강사님 강의 잘 듣고 있는 전진호 학생입니다.첫번째 캡쳐사진은 제가 강의를 들으면서 적었던 코드에서 상품 주문을 클릭하고, 아무 것도 적지 않았을 때 나오는 화면입니다.두번째 캡쳐사진은 자료 소스 코드에서 동일한 작동을 했을 때 나오는 소스코드입니다. 똑같은 status=400, Bad Request인데 첫번째만 왜 에러 로그가 길게 나오는 걸까요?답변해주시면 감사하겠습니다. *) zip 파일을 export 했는데 어떻게 올려야 할지 잘 모르겠어서 추가적으로 필요하시다면 보내드리겠습니다.    

강의를 다 보고 따로 찾아보니 @Transactional은 controller가 아닌 service에서 사용해야되고 controller에서 사용하게 되면 트랜잭션이 적용이 안된다고 하길래 직접 해봤습니다. controller의 메소드에 @Transactional을 붙여서 로직을 실행시켜보니 변경감지가 일어나서 update 쿼리가 날라가는 것을 확인하였는데 이러면 트랜잭션을 통해서 변경감지가 일어난 것 아닌가요?

안녕하세요. 강의를 보던중 의문이 생겨 질문 드립니다.JpaRepository를 만들면 정의하지 않아도 findById는 기본적으로 존재 하는 것으로 알고 있습니다.findByIdWithPessimisticLock를 사용한 매서드가 락을 반납하기 전에 다른 매서드에서 findById을 이용한 update가 발생하게 된다면 findById가 Lock을 감지하는지가 궁금합니다. public interface StockRepository extends JpaRepository<Stock, Long> {@Lock(value = LockModeType.PESSIMISTIC_WRITE)@Query("select s from Stock s where s.id=:id")Stock findByIdWithPessimisticLock(Long id);}  

build.gradle에서 useJUnitPlatform()부분에 No candidates found for method call useJUnitPlatform. 에러가 뜨는 이유가 먼가요? 스프링부트 3.1버전이라 Jdk 는 17로 맞춰놓은 상태입니다.

[질문 템플릿]1. 강의 내용과 관련된 질문인가요? (아니오)2. 인프런의 질문 게시판과 자주 하는 질문에 없는 내용인가요? (예)3. 질문 잘하기 메뉴얼을 읽어보셨나요?

.jsp 파일 생성하면 파일을 intellj가 .jsp파일이라고 인식은 합니다. 빨간색으로 jsp파일이라고 나타나는데요, 저는 강사님처럼 특정 키워드가 색깔로 표시되지가 않습니다ㅠㅠ모든 코드가 다 흑백이에요어떻게 하면 색깔을 입힐 수 있을까요?

(예/아니오)[질문 내용] 제가 이해한 것은 new를 사용하면 계속 새로운 내용으로 바뀔 때마다 new 객체가 생성되어 new대신 public MemberService(MemberRepository memberRepository){ this.memberRepository = memberRepository; }을 사용하는 것인가요?이러한 방법이 DI가 맞나요?

안녕하세요. 테스트 코드에 보이는 쿼리에 대해 질문이 있습니다!테스트 코드를 실행시키면 getLock 쿼리가 쭉나오고 releaseLock 쿼리가 쭉 나오고 있는데요Lock을 반환시켜야만 lock을 획득할 수 있다면 getLock() releaseLock() 순서로 반복되는 쿼리가 나와야 하는게 맞지 않나요? 

MemberRepository를 개발할 때, @PersistenceContext를 사용할 때와 @RequiredArgsConstructor를 사용할 때 테스트 결과가 달라져서 문의남깁니다.@PersistenceContextprivate EntityManager em;은 가능하지만, @RequiredArgsConstructor를 사용할 때는 final이 들어가야만 하던데 왜 그런지 알 수 있을까요?

안녕하세요 태현님, 항상 좋은 강의 감사드립니다.다름이 아니라 저희는 직접 ec2의 서버 내에서 create table을 해주었는데 aws의 rds 라는 데이터베이스 서비스를 사용하는 것과의 차이가 궁급합니다. 굳이 rds를 빌릴 필요가 없는 것일까요?

이렇게 했는데 localhost:8080/api/members/bad 경로로 GET요청을 보냈는데 status가 계속 500이에요.error도 "internal Server Error"로 나와요

강의를 다 수강하고 깃허브 코드 참조하여 작성했습니다.현재 SecurityConfig 코드는 다음과 같습니다.@Configuration @EnableWebSecurity @RequiredArgsConstructor public class SecurityConfig{ private final UserRepository userRepository; private final CorsConfig corsConfig; @Bean public SecurityFilterChain filterChain(HttpSecurity http) throws Exception { return http .csrf(AbstractHttpConfigurer::disable) .sessionManagement((sessionManagement) -> sessionManagement.sessionCreationPolicy(SessionCreationPolicy.STATELESS) ) .formLogin(withDefaults()) .httpBasic(withDefaults()) .apply(new MyCustomDsl()) .and() .authorizeRequests(requests -> requests .requestMatchers("/user/**").authenticated() .requestMatchers("/admin/**").access("hasAuthority('ADMIN')") .anyRequest().permitAll() ) .build(); } public class MyCustomDsl extends AbstractHttpConfigurer<MyCustomDsl, HttpSecurity> { @Override public void configure(HttpSecurity http) throws Exception { AuthenticationManager authenticationManager = http.getSharedObject(AuthenticationManager.class); http .addFilter(corsConfig.corsFilter()) .addFilter(new JwtAuthenticationFilter(authenticationManager)) .addFilter(new JwtAuthorizationFilter(authenticationManager, userRepository)); } } } filterchain에서 and()에 오류가 발생합니다.'and()' is deprecated and marked for removal 로 나오는데 and가 deprecated된 거 같지는 않고 커스텀 필터를 적용하는 것에서 뭔가 문제가 있지 않을까 싶습니다만 이틀째 해결을 못하고 있어 문의남깁니다ㅠㅠ

Order 클래스에 작성한 createOrder 입니다. Order order = Order.createOrder 에서 마지막 매개변수를 불러오지 못하고 있습니다.불러올 수 있는 값에도 orderItem이 없습니다. 어떻게 해결해야 할까요 ?

안녕하세요, 김영한님 야생형 스타일로 강의 잘 듣다가 질문드립니다.질문을 적다가 order가 형성되는 순간에 해당 order와 입력된 orderItem과 연결이 되는 거 같다는 생각이 들었습니다. 제가 생각한 게 맞는지 질문드립니다. 정리하자면, OrderService에서 order 메소드를 실행할 때 orderItem과 생성된 order_id는 order가 생성되는 순간 해당 order_id와 orderItem와 연결되는 건가요? 답변해주시면 감사하겠습니다.감사합니다.

SQLExceptionTranslator translate의 파라미터가 (String task, @Nullable String sql, SQLException ex) 이런식으로 되어있던데 첫번째 task에 무엇을 넣어야하는지 궁금합니다. 맥락상 실행한 메서드명을 넣는 것 같은데 이것저것 변경해보다가 전혀 관련없는 글을 써넣어도 정상작동하던데 task에 무엇을 넣는지, 어떤 역할을 하는지 궁금합니다.
