IDENTITY 전략은 em.persist() 시점에 즉시 INSERT SQL 실행 하고 DB에서 식별자를 조회 라는 내용과 관련하여 질의드립니다. commit을 주석처리하여도 정상적으로 insert되는게 확인되었습니다. 근데 실질적으로 db에 저장된 값은없는데 이러한경우 영속성컨텍스트에만 저장이되어있는 상태인건가요?! 

sx1, sy1 = 0, 0 #좌측 상단의 좌표값sx2, sy2 = 0, 0 # 우측 하단의 좌표값sx1 = self.cx - self.width/2sy1 = self.cy - self.height / 2sx2 = self.cx + self.width/2sy2 = self.cy + self.height / 2     이 코드대로라면 sx1,sy1 은 좌측하단이고 sx2,sy2가 우측상단이 되는거아닌가요..? 터틀그래픽이 그리는것도 시작점은 좌측하단에서 시작하던데

실습하고 실행해보니가 아래와 같은 에러가 발생하는데    구글링으로 아무리 찾아도 답을 찾기 힘들어서 질문드립니다!!    

선생님 ~~ 저번에 접수하고 늦잠자서 시험못가고 ㅜㅜ 오늘 드뎌 실기시험 봤어요~~!! 이제 시험도 끝나고해서 커리큘럼 따라가면서 꼼꼼하게 공부하러구 하는대요#~!!   시즌1 시즌2 css중상급 이렇게 순서대로 공부할까요? 아님 css수업 부터 들을까요?   강의는 인프런 이벤트 할때 다 구입해뒀어용!

안녕하세요 강사님 장고 데이터베이서 중에서 mariadb는 혹시 지원을 못하는걸까요?    사용가능한 리스트에 없어서 문의드립니다!

학습하는 분들께 도움이 되고, 더 좋은 답변을 드릴 수 있도록 질문전에 다음을 꼭 확인해주세요.1. 강의 내용과 관련된 질문을 남겨주세요.2. 인프런의 질문 게시판과 자주 하는 질문(링크)을 먼저 확인해주세요.(자주 하는 질문 링크: https://bit.ly/3fX6ygx)3. 질문 잘하기 메뉴얼(링크)을 먼저 읽어주세요.(질문 잘하기 메뉴얼 링크: https://bit.ly/2UfeqCG)질문 시에는 위 내용은 삭제하고 다음 내용을 남겨주세요.=========================================[질문 템플릿]1. 강의 내용과 관련된 질문인가요?

JpashopApplication.java 는 동작이 잘 되나, 테스트코드에서만 발생해요. org.h2.jdbc.JdbcSQLNonTransientConnectionException: Wrong password format, must be: file password <space> user password [90050-212] at

private List<AddressEntity> 에서  왜 @joincolumn(name="member_id")여기에 joincolumn이 썼는지하고 member_id가있는지 모르겠습니다 원래 addressentity에 써져있어야되는거아닌지하고요 연관관계의 주인때문에요 

package hello.core.singleton; public class SingletonService { private static SingletonService singletonService=new SingletonService(); public static SingletonService getInstance(){ return singletonService; } private SingletonService(){ //System.out.println(singletonService); } }  System.out.println(singletonService); // 이 부분이요 !!!!  자바가 뜰때 -> 자동으로 내부적으로 객체 생성해서 -> 참조값이 instance에 들어간다는 이해했습니다. 그래서 생성자에 출력문을 써서 값을 확인해보니 null로 뜹니다 !! 왜 그럴까요??

안녕하세요. 강의 잘 듣고 있습니다.  AAA인증 단계 교육 듣고 있는데요. 강의와 함께 실습을 따라해보던 중 PC쪽에서는 서버까지 핑이 잘 나가는데 반대로 서버쪽에서는 PC쪽으로 핑이 안나가는데요. 서버/라우터1/라우터2 쪽에서 AP까지의 핑이 막힙니다. 이게 정상인지 궁금하구요.. 만약 그렇다면 그 이유가 궁급합니다. 

그 활용1강의에서 List<Order> 이런거 썼었는데 그떄는 저런 어노테이션이 하나도 없었는데 이 강의를 보면서 처음보는 어노테이션이라 생략이된건가요?

문제는 풀었는데  res = res * 10 + t같이 한번에 짧게 풀 수 있는 코드를 생각못하겠어요. 아직 저는 시간이 남았지만 코테를 볼 때 즈음이면 이러한 코드를 보고 외워야 되는건지...아니면 그냥 이대로 풀어도 되는건지 모르겠습니다. 이대로 풀면 잘은 모르지만 시간복잡도나 공간복잡도 배울때 값이 엄청 클거 같아서 고쳐야 할 부분은 고쳐야 할 것 같습니다. 현재는 선생님의 코드를 보고 "아 이렇게 활용할 수 있겠다랑 이게 있었지" 하고 메모하지도 않고 다음 문제를 푸는데 앞으로 다른 선생님이나 푸신 분 들의 코드를 보고 어떠한 생각을 하고 앞으로의 문제풀이에 접근하는게 좋을까요? 밑은 제가 영상을 안보고 푼 풀이입니다. a = int(input())b = list(map(int, input().split()))def reverse(x): c = [0] * (6) count = 0 hap = 0 while x >= 1: c[count] = x % 10 count += 1 x = x // 10 if x < 1: for t in range(count): hap += c[t] * 10**(count-1-t) return hapdef isPrime(x): cnt = 0 for i in range(2,x): if x % i != 0: cnt += 1 if x == cnt + 2: return xt = [0]*afor i in range(a): t[i] = reverse(b[i])for sd in range(len(t)): if isPrime(t[sd]) != None: print(isPrime(t[sd]), end=" ")

안녕하세요! 덕분에 수업 잘 듣고 있습니다.   배열에 값을 추가하기 위해서 .push 를 사용하고 객체에 값을 추가,변경하는 것은 알겠는데,   배열의 형태에 객체를 추가하는 것은 어떻게 하는건가요~?   예를들어,   var product = [{ title: '농구공', description: '농구의 황제 조던이 사용했던 농구공', price: 50000 },{ title: '축구공', description: '축구 황제 메시가 사용했던 축구공', price: 60000 }]   와 같이 product 변수가 정의 되어 있을 때,   세번째 배열에 {title: '골프공',description: '골프 황제~~~'price: 70000} 과 같은 객체를 추가하려고 할 때 어떤 식으로 하는지 궁금합니다.   감사합니다!

어떤 걸 공유하고싶어서 쓰고싶다고하면 의도해서 변경되게 entity를 쓰라고하셨는데 그게 어떤건지 예를들어서 알수있을까요 이해가 안가서요 entity를 쓴다는게..   그리고 embedded 타입이 공유가 위험하다고하는데 그 앞강의에서는 여러곳에서 사용이 가능해서 재사용성이 좋다는 장점이있는데 장점이 그럼 아닌게 아닌가요?

안녕하세요. 질문 하나 남기고 싶습니다. 첫번째 질문은.. 일단 WAS `/error-page/500` 다시 요청 한 상황이라고  생각하고, 그 다음 동작이 '필터' 로 가는 것인데  필터로 간다는 것이 chain.doFilter(request, response) 로 바로 간다는 것인가요? try { log.info("REQUEST [{}][{}][{}]", uuid, request.getDispatcherType(), requestURI); chain.doFilter(request, response);} catch (Exception e) { log.info("EXCEPTION {}", e.getMessage()); throw e;} finally { log.info("RESPONSE [{}][{}][{}]", uuid, request.getDispatcherType(), requestURI);}   두번째 질문은.. 첫번째 질문 이어서 설명입니다. 하나 변경된게 있다면,  WebConfig 클래스에서 setDispatcherTypes() 안에 DispatcherType.ERROR 를 뺀 상황입니다. 이 상황에서는 doFilter 위에  있는 log.info("REQUEST ...) 가 수행이 안되고 바로 chain.doFilter(request, response) 로 가는건지 궁금합니다.   혹시 제가 잘못알고 있거나 그런 부분이 있다면 설명 부탁드리겠습니다 ㅠㅠ

연관관계 메서드를 보통 엔티티에서 만든다고하셨는데 근데 만들때 대부분이 세터가 필요하지않나해서요 그런데 제가 엔티티에는 세터를 만들지 말아야된다고 배웠는데 어떻게 메서드같은걸 만들어야할까요

제가 몇달전에 이강의를 수강하면서 엔티티를 정의하는 클래스 즉, 지금 이 강의의 예제로 말하면 Member 라는 클래스에서 CITY라는 컬럼의 값을 city = "Seoul" 이렇게 엔티티 레벨에서 할당시키는건 좋지않은 방식이라고 설명해드렸던게 생각이 나는데 제가 제대로 이해한게 맞나요?설령 아니라면enum타입의 경우 @Column 어노테이션의 속성중 default로 enum타입의 인스턴스중 한개를 기본값으로 둘 수 있는 default 속성이 있던데 이걸 사용하는 방식도 제가 첫번째로 질문드렸던 사안에 어긋나는 행동인가요?   그리고 만약 엔티티 레벨에서 값을 할당 시키는게 좋지 않은 방식이라면 왜 이런 방법이 좋지 않은 방법인건가요?
