안녕하세요 강사님. 이번 수업을 듣다가 오류가 나서 질문드려요 강의와 관련있는 질문 을 남겨주세요. org.hibernate.hql.internal.ast.ErrorTracker reportError ERROR: <AST>:1:36: unexpected AST node: . 우선 JpaMain 클래스 입니다. public class JpaMain { public static void main ( String [] args){ EntityManagerFactory emf = Persistence . createEntityManagerFactory ( "hello" ); //PersistenceUnitName EntityManager em = emf .createEntityManager(); EntityTransaction tx = em .getTransaction(); tx .begin(); try { Member member = new Member(); member .setUsername( "member1" ); member .setAge( 10 ); em .persist( member ); em .flush(); em .clear(); List < Member > result = em .createQuery( "Select m from Member m where m.username" , Member . class ).getResultList(); // 엔티티 프로젝션 Member findMember = result .get( 0 ); findMember .setAge( 20 ); //List<Team> result=em.createQuery("Select m.team from Member m join m.team",Team.class).getResultList(); // 엔티티프로덕션 //em.createQuery("Select o.address from Order o",Address.class).getResultList(); // 임베디드 타입 프로덕션 //List resultList = em.createQuery("Select distinct m.username, m.age from Member m").getResultList(); // 스칼라 타입 프로젝션 //Object o=resultList.get(0); //Object[] result=(Object[]) o; //System.out.println("username = "+result[0]); //System.out.println("age = "+result[1]); tx .commit(); } catch ( Exception e){ tx .rollback(); } finally { em .close(); } emf .close(); } } 엔티티 프로젝션을 실습하는데 오류가 나서 질문 드립니다. 엔티티 프로덕션, 임베디드 타입 프로젝션, 스칼라 타입 프로젝션 은 잘 작동 되는데 엔티티 프로젝션은 오류가 납니다. h2 데이터베이스에는 테이블만 생성될 뿐 데이터가 삽입되지 않았습니다.ㅠㅠ...

안녕하세요. 현재 Postman 강의를 듣고 있습니다. mock 서버를 생성하려고 하면 아래의 이미지와 같은 에러 메시지가 발생하는데 어떻게 해결해야 하는지 잘 모르겠습니다. [질문이미지] no mock server calls yet 이 나오면서 mock server가 생성되지 않아서 실습을 진행하지 못하고 있습니다. 이때 어떻게 해결해야 하는지 가르쳐 주시면 감사하겠습니다.
여러가지 실험을 하다가 OnHitEvent() 함수 안에다 제가 분기문을 모두 주석처리 후 State = PlayerState.Moving 으로 한 뒤 플레이를 해봤습니다. OnHitEvent() { State = PlayerState.Moving } 그런데 이렇게 하면 캐릭터를 한번 공격한 후 유니티짱을 다른 곳을 클릭해서 움직이려 할 때 먹통이 되어 안움직이게 됩니다. 제가 생각하기로는 OnMouseEvent로 계속해서 이벤트를 듣고 그에따른 로직을 수행해야 할 것으로 생각이 되는데 OnMouseEvent_IdleRun 내부 최상단에 debug.log를 찍어보니 해당 함수가 호출도 않되더군요 영상대로 OnHitEvent에 State = PlayerState.Idle 이면 정상적으로 수행이 됩니다만 위의 사항이 아무리 고민해도 왜 그런지 모르겠어서 질문드립니다.
업무자동화 + 웹크롤링 강의 듣고 싶은데 예전에 다른 분 질문 답변에 이와 관련하여 강의 계획중이라고 하신걸 본것 같아 문의드려요! 혹시 언제쯤 강의가 개설될지 대략적으로라도 알려주시면 감사하겠습니다. ex1) 올해 상반기 안에는 나올꺼 같다. ex2) 아니다 무슨소리냐 데이터 기반 주식 퀀트투자 part2를 먼저 강의할 것이기 때문에 아직 한~참 멀었다.
안녕하세요, 에릭쌤~ 대부분 최상단 네비게이션 바와 메인 배너 사이에, 그리고 메인 배너 하단에 구분선을 넣어주던데요. 사실 주위 오브젝트 색상에 따라 시각적으로 애써 보지 않으면 거의 잘 안 보이는 경우도 많던데 왜들 꼭 구분선을 넣어주나 궁금증이 들었습니다. 단순히 디자인 측면이 아니라 기능적인 용도나 특별한 이유가 있을까요?
강사님 제가 스프링 입문 강의에서 만든 프로젝트에서 member클래스에 phoneNumber라는 이름으로 varchar(255)형 필드를 하나 추가했습니다. memberForm에도 추가를 해주고 스프링 통합 테스트를 돌릴 때도 member 객체를 생성하고 set으로 phoneNumber를 추가를 해줬는데도 다음과 같은 오류가 납니다. 왜 그런 걸까요 ㅠ (오류 코드는 아래와 같습니다.) 2021-03-06 21:46:04.645 INFO 14452 --- [ main] o.s.t.c.transaction.TransactionContext : Began transaction (1) for test context [DefaultTestContext@5b068087 testClass = MemberServiceIntegrationTest, testInstance = hello.project1.service.MemberServiceIntegrationTest@1b800a11, testMethod = 회원가입@MemberServiceIntegrationTest, testException = [null], mergedContextConfiguration = [WebMergedContextConfiguration@6f152006 testClass = MemberServiceIntegrationTest, locations = '{}', classes = '{class hello.project1.Project1Application}', contextInitializerClasses = '[]', activeProfiles = '{}', propertySourceLocations = '{}', propertySourceProperties = '{org.springframework.boot.test.context.SpringBootTestContextBootstrapper=true}', contextCustomizers = set[org.springframework.boot.test.autoconfigure.actuate.metrics.MetricsExportContextCustomizerFactory$DisableMetricExportContextCustomizer@387a8303, org.springframework.boot.test.autoconfigure.properties.PropertyMappingContextCustomizer@0, org.springframework.boot.test.autoconfigure.web.servlet.WebDriverContextCustomizerFactory$Customizer@d2de489, org.springframework.boot.test.context.filter.ExcludeFilterContextCustomizer@41330d4f, org.springframework.boot.test.json.DuplicateJsonObjectContextCustomizerFactory$DuplicateJsonObjectContextCustomizer@24c1b2d2, org.springframework.boot.test.mock.mockito.MockitoContextCustomizer@0, org.springframework.boot.test.web.client.TestRestTemplateContextCustomizer@565f390, org.springframework.boot.test.context.SpringBootTestArgs@1, org.springframework.boot.test.context.SpringBootTestWebEnvironment@7f416310], resourceBasePath = 'src/main/webapp', contextLoader = 'org.springframework.boot.test.context.SpringBootContextLoader', parent = [null]], attributes = map['org.springframework.test.context.web.ServletTestExecutionListener.activateListener' -> true, 'org.springframework.test.context.web.ServletTestExecutionListener.populatedRequestContextHolder' -> true, 'org.springframework.test.context.web.ServletTestExecutionListener.resetRequestContextHolder' -> true, 'org.springframework.test.context.event.ApplicationEventsTestExecutionListener.recordApplicationEvents' -> false]]; transaction manager [org.springframework.orm.jpa.JpaTransactionManager@652a1a17]; rollback [true] Hibernate: select member0_.id as id1_0_, member0_.name as name2_0_, member0_.phone_number as phone_nu3_0_ from member member0_ where member0_.name=? 2021-03-06 21:46:05.163 WARN 14452 --- [ main] o.h.engine.jdbc.spi.SqlExceptionHelper : SQL Error: 42122, SQLState: 42S22 2021-03-06 21:46:05.163 ERROR 14452 --- [ main] o.h.engine.jdbc.spi.SqlExceptionHelper : Column "MEMBER0_.PHONE_NUMBER" not found; SQL statement: select member0_.id as id1_0_, member0_.name as name2_0_, member0_.phone_number as phone_nu3_0_ from member member0_ where member0_.name=?

3:37초에 한번에 컨테이너, 이미지.네트워크 모두 삭제하고 싶다라는 말은 A에서 다른환경의 B에게 보낸후에 A 에게 남아있는 컨테이너 잔여를 말하는건가요? 예를들어 카카오톡을 설치파일을 다운 받으면 설치 후에도 남아있는 install 파일이 저 쓰지않는 도커랑 비슷할까요? 커맨드도 중요하지만 중간중간 이 커멘드를 치면 이렇게 동작해 라는 이미지가 있으면 더욱 이해도가 높아질거 같습니다 흑흑 ㅠ
안녕하세요 이해하기 쉽게 알려주시는 도커 강의 너무 만족하고 잘 보고있는 학생입니다 영상을 보다가 Stop 과 Kill을 보여 의문점이 생겨서 문의 드립니다 제가 여기 강의에서 배운 도커라는 개념은 A에서 환경(버전,os...) 뭔가가 다른 환경에서 파일이나, 데이터를 컨테이너에 실어서 전송해준다 라고 이해를 하였습니다 근데 Stop 이랑 Kill 이라는 것은 전송하고 싶은 데이터를 전송하는 중에 Stop이나 Kill을 써서 중단을 한다는 말인가요? A에서 B로 배포나 뭔가를 옮길때 굳이 저 Stop과 Kill을 쓸 일이 있을지 의문입니다 어차피 통신은 양쪽다 된다는 가정하에 뭔가를 옮기는 행위를 도커라 배웠는데 Kill이나 Stop이 어디에 쓰이는지 궁금합니다 저같으면 일단 파일을 모두 보낸후에 받은 쪽에서 그냥 지울거 같습니다 통신중인걸 중간에 지우지 않고 아니면 혹시 A에서 B로 24시간 뭔가를 계속 쏴주어야 하나요?? 혹시 제가 이해하고 있는 개념이 도커의 개념과 많이 다르다면 힌트좀 부탁드립니다 꾸벅
a = 3 b = 0 while b=a: print(a) b=b+1 위와 같이 코드를 짰습니다. 코드를 짠 목적은 3이 3번 출력되도록 하기 위함입니다. 코드를 짜고 난 후 실행을 하니 while b=a: ^ SyntaxError: invalid syntax 와 같은 오류가 납니다. 이유가 뭔가요?
안녕하세요! 저는 강사님처럼 똑같이 따라했는데 톰캣도 연결이 잘 된 것 같거든요 그런데 localhost:8080을 치면 "whitelabel Error Page"가 떠버려요.. 그래서 index.html 파일에 오른쪽버튼을 클릭하여 마우스를 놓고 "run index.html" 을 클릭하여야 hello가 쓰여있는 페이지가 뜨는데 왜 이러는 걸까요? 그리고 이렇게 되도 정상인 건가요..?ㅠㅠ 톰캣에 문제가 있는 걸 까요 ㅠㅠ
저도 가로스크롤이 생겨 질문을 찾아보게 되었는데 가로스크롤에대해서 여쭤보신분 답글에 선생님이 영상을 업데이트해주신다는 댓글을 보았습니다. 영상을 다시 보았는데 혹시 아직 업데이트가 안된것이 맞나요 ? 소스코드에는 card-list-con이라는 div태그가 추가되어있는게 확인이 됬습니다!
댓글 숫자를 출력하려고 하는데 그대로 옆에 텍스트를 추가하는 방식은 안되던데 ex) {post.comments.length} 좋은 방법 알려주시면 감사여 https://github.com/node-hyun/nodebird-deploy/blob/master/front/components/PostCard.js
