(예)[질문 내용]강사님. 엔티티 자바파일 생성 후 서버 구동시 DB에 해당 엔티티에 들어있는 필드들이 컬럼으로 생성이 되는것은 잘 알고 있습니다.그런데 컬럼으로 생성이 안되는 조건이 궁금합니다.왜 궁금하냐면, 예를들어 강이의 Order 엔티티에서 setMember, addOrderItem, getTotalPrice 등의 메서드들은 DB에 필드 생성이 되지 않아서 입니다.DB에 컬럼이 생성되는 조건/생성되지 않는 조건이 궁금합니다.

안녕하세요 김영한님! 강의 아주 잘 듣고있습니다!! 현재 김영한님 첫번째 강의를 다 듣고 저 혼자 만들어보고 싶은게 생겨서 만드는중인데요 현재 제가 군대에 있어서 사지방에서 코딩을 하느라 인텔리제이를 사용하지 못하고 깃허브에서 제공하는 codespaces와 gitpod을 사용하여 vscode 환경에서 코딩하는 중입니다. 근데 jpa의 JpaRepository나 lombok 혹은org.springframework.boot.autoconfigure.SpringBootApplication 이런 패키지들이 계속 does not exist라고 뜹니다. 김영한님꺼 따라할때는 잘 됐는데 이제 제가 혼자서 만들고 싶은거 만드려니 확실하지도 않고 실행도 잘 안돼서 패키지를 못읽는건지도 잘 모르겠습니다. 현재 build.gradle에 의존성도 다 넣어있고 vscode의 패키지 설치에도 java extention pack, lombok, spring extention pack또 다 깔았습니다. 당연 재설치도 해보았구요! 구글링을 지금 며칠째 하고있는데 도저히 안되서 여기에 질문 올려봅니다...springboot version : 3.1.3jdk version : 17   

서버도 켜고 인바운드 규칙도 변경했는데 서버에선 22 이 르스닝으로 방화벽이 안뚫려서 접속이 안된거 같은데 어떻게 해결하나요ㅠㅠ

영한님의 JPA 서적/강의로 JPA를 학습하는 동시에 개인 프로젝트를 병행하여 JPA에 대한 연습을 하고 있습니다.Unique 제약 조건을 추가하는 과정에서 궁금증이 생겨 질문 드립니다. 영속성 컨텍스트는 그 자체로 Unique 제약 조건을 검증하지 않나요?chatGPT에게 질문을 했을 때의 '영속성 컨텍스트는 unique 제약 조건을 확인하지 않고 DB에 해당 역할을 위임한다; 라고 대답하였는데, 달리 검증할 방법을 모르겠어 이곳에 질문 드립니다.아래와 같은 상황을 방지하기 위해서는 데이터 저장 로직에 em.flush()를 함께 써 주는 것이 가장 바람직한 접근 방법일까요?영한님의 다른 답변을 참고하면 데이터 저장의 빈도수가 상대적으로 적기 때문에 em.flush()를 한번 더 호출하는 것이 큰 성능 저하를 가져오지 않을 것 같고, 문제 해결도 되는 것 같습니다만, 제가 놓치는 부분이 있을까 하여 질문 드립니다.테스트에 @Rollback(value=false)를 추가하면 데이터가 예상한 대로 실패하던데, 해당 어노테이션의 유무가 어떤 차이를 가지기에 결과가 달라지는건지 함께 여쭤봐도 될까요??강의 내용에 대한 질문보다는, 강의 내용에 기반을 둔 프로젝트 질문이라 여기에 질문을 드려도 되는지 모르겠습니다만, 혹여나 도움을 받을 수 있을까 하여 질문 드립니다. '영속성 컨텍스트의 동작 원리' 쯤 내용들은 관련 자료가 쉽게 찾아지지 않아 궁금증을 어떤 식으로 해결할 수 있을지 모르겠습니다 ㅠㅠ질문 이해를 돕고자 아래에 문제 상황도 함께 추가하여 질문 드립니다. 배경 설명질문 상황이 이해가 쉽도록 최대한 간단히 프로젝트 구성 설명 드립니다.유저의 데이터를 저장하는 DAO를 구현 중입니다.  User 모델@Entity @Table(name = "USERS") @Getter @Setter @NoArgsConstructor public class User { @Id @GeneratedValue @Column(name = "IDX") private Long idx; @Column(name = "NAME") private String userName; @Column(name = "ID", unique = true) private String id; @Column(name = "PASSWORD") private String password; }유저의 ID가 중복되지 않도록 ID 컬럼에만 @Column( ... unique = true) 를 사용하였습니다. UserDAO@Repository public class UserDAO { @PersistenceContext private EntityManager em; public long save(User user){ em.persist(user); return user.getIdx(); } //... } 마지막으로, Unique 제약 조건을 확인하기 위한 테스트 코드 입니다.중복되는 ID 값을 가진 유저를 저장할 때 어떤 예외가 발생하는지 직접 확인하기 위해 실패하는 테스트 코드를 작성하였습니다. UserDAOTest @ExtendWith(SpringExtension.class) @SpringBootTest class DBUserDAOTest { @Autowired UserDAO userDAO; @Test @Transactional public void sameIdSaveTest(){ //given DBUser user1 = new DBUser("User1", "sameId", "PW1"); DBUser user2 = new DBUser("User2", "sameId", "PW2"); //when long savedIdx1 = userDAO.save(user1); long savedIdx2 = userDAO.save(user2); //that } 문제 상황동일한 ID 값인 "sameId"를 사용했음에도 문제가 없이 테스트가 통과하는 모습입니다. 로직 변경public long save(DBUser user){ em.persist(user); em.flush(); return user.getIdx(); }위와 같이 em.flush()를 추가하면 예상과 같이 테스트가 실패합니다.DataIntegrityViolationException이 발생합니다. 

[질문 템플릿]1. 강의 내용과 관련된 질문인가요? 예2. 인프런의 질문 게시판과 자주 하는 질문에 없는 내용인가요? 예3. 질문 잘하기 메뉴얼을 읽어보셨나요? 예[질문 내용]안녕하세요. 저는 현재 springboot 2.7.16버전 사용 중입니다. 배포파일 만드는 과정에서 ./gradlew clean build를 했는데 에러가 발생합니다.해결 방법이 있을까요?ㅠ

RDB 사용시 좋아요나 조회수 같은 자주 변경되는 데이터에 Pessimistic Lock을 걸면 락을 자주 걸어 성능 저하가 발생할 수 있고 Optimistic Lock의 경우도 롤백되는 경우가 많아져 성능 저하가 발생할 수 있습니다.이때 데이터가 엄청 많지는 않아 Redis가 아닌 로컬 캐시를 사용해서 해결해보려 한다면 synchronized 키워드를 사용해서 애플리케이션에서 동시성 문제를 해결하고 일정 시간에 한번씩 RDB와 동기화 하는 방식을 생각해보았는데 이렇게 하는 경우도 있나요?

안녕하세요 강사님. 섹션 0 (윈도우) Java, IntelliJ, PostMan, MySQL, git 설치영상 보면서 IntelliJ 설치중인데요설정부분에 보니까 cannot find the specified shell scripts location in the system path라는 빨간 문구가 떠 있는데 그냥 넘어가도 괜찮을까요? 

왜이런건가요??켜졌다가도 금방꺼집니다

  위와 같이 영상 풀이랑 똑같이 따라 해보았는데 main메소드에서 setDetector,setReporter를 호출할때 static으로 선언하라며 에러가 나네요.. 아무리봐도 똑같은 코드인데 뭐가 문제인지 질문드립니다!

강의 너무 잘 보고 있습니다!!!백엔드 Java 개발자를 꿈꾸는 대학생입니다!!다름이 아니라 혹시 강의에서 배운 내용을 제 개인 블로그에 정리해도 될지 궁금해서 글 남깁니다!!!

(예)[질문 내용]2:00 부분에서 "생성자가 하나만 있으면 @Autowired를 생략할 수 있다"라고 하셨는데그런 이유가 아니더라도 SpringConfig에 MemberRepository가 스프링 빈으로 등록이 되어 있으니, 그것의 구현체인 JdbcTemplateMemberRepository의 생성자에@Autowired를 붙이지 않아도 되는 거 맞나요?예전 강의에서 SpringConfig에 등록된 MemberService 등은, MemberService 클래스에서 @Service, @Autowired를 지웠던 기억이 있어서 그렇습니다.

(예)[질문 내용]컴포넌트 스캔과 자동 의존 관계 설정 방법을 통했을 때는 MemberService가 아래 코드와 같았었는데@Service public class MemberService { private final MemberRepository memberRepository; @Autowired public MemberService(MemberRepository memberRepository) { this.memberRepository = memberRepository; } } MemberService를 SpringConfig에 등록한 이후로는 아래 코드와 같이 @Service와 @Autowired를 지웠잖아요?public class MemberService { private final MemberRepository memberRepository; public MemberService(MemberRepository memberRepository) { this.memberRepository = memberRepository; }이 경우엔 생성자 주입 방식의 경우인데 만약 필드 주입 방식을 사용한다면 @Autowired를 어떻게 해야 하나요? 1) 컴포넌트 스캔과 자동 의존 관계 설정 방법일 땐 필드에 @Autowired를 붙이고@Service public class MemberService { @Autowired private MemberRepository memberRepository; }    2) 자바 코드로 직접 스프링 빈 등록하기 방법(SpringConfig에 등록)일 땐 필드에 @Autowired를 붙이지 않아도 되나요?public class MemberService { private MemberRepository memberRepository; }

(예)[질문 내용]강의를 쭉 따라왔습니다.궁금한 점이 있는데 통합 테스트 클래스인MemberServiceIntegrationTest에서 필드 주입 방식으로@Autowired MemberService memberService; @Autowired MemberRepository memberRepository; 이렇게 선언했잖아요?그런데 SpringConfig에서 MemberService랑 MemberRepository를 스프링 빈으로 등록했으니깐여기서도 @Autowired를 빼도 될 것 같았는데오류가 나더라구요. 이유를 뭔가 알 것 같기도 하면서 개념이 좀 헷갈리는데 @Autowired를 붙여야 하는 이유가 뭔가요?
