플리퍼를 공식 사이트에서 윈도우 버전으로 다운 받고 실행하는데 다음과 같은 에러가 뜹니다이 에러를 해결하고자 터미널을 키고 배쉬와 파워쉘에서 sudo kill $(lsof -t -i :52342) 이 코드를 쳐봤는데이런 식으로 나옵니다... 혹시나 해서 컴퓨터를 모두 종료하고 다시 시작해서 다른거 실행 안하고 플리퍼부터 실행했는데도 똑같은 문제가 발생하네요 이 문제에 대해 아이디어를 주실 수 있나요??? ㅠㅠㅠ

(예/아니오)[질문 내용]안녕하세요. 강의 잘 듣고 있습니다.예외처리 API 강의를 듣다보니 궁금한 점이 생겨 질문 드립니다. api를 사용하는 경우 validation을 어떻게 하는지 궁금합니다. 강의에서는 model과 view를 사용하여 bindingresult에 hasError를 사용하여 검증 성공 실패를 판단하여 view에서 타임리프를 활용해 에러 메세지등을 표시해주었는데요. api의 경우 찾아본 결과 bindinresult를 사용하지 않는 것을 확인 하였습니다. 여기서 그렇다면 api의 경우는 valid가 실패했을 시 어떤 과정이 일어나는지 궁금합니다. 검증이 실패한 것을 어떻게 확인하며 또 이 상황을 어떻게 처리하는지 궁금합니다. 또한 검증과 예외의 정확한 차이를 잘 모르겠습니다. 검증이 실패했을 경우도 exception이 터진 상황일까요?

안녕하세요 저는 지금 문자열연산 강의를 듣고 있는데text1 = "#내꺼하자"text2 = "#오늘부터1일"text3 = total_text = text1 + text2 + text3print(total_text)여기서 " 이녀석이 자동으로 닫혀야하는데 안되서 막혀있습니다ㅠㅠ 어떻게 하나여? 

오류의 문제를 못 찾겠습니다 어떻게 해야 하나요 ?

[질문 템플릿]1. 강의 내용과 관련된 질문인가요? (예/아니오)2. 인프런의 질문 게시판과 자주 하는 질문에 없는 내용인가요? (예/아니오)3. 질문 잘하기 메뉴얼을 읽어보셨나요? (예/아니오)[질문 내용]status는 트랜잭션 설정, 상태에 관한 정보인데, 이미 transactionManager는 생성할 때 dataSource를 넣어줬고, 또 트랜잭션 동기화 매니저가 있기 때문에 어떤 커넥션을 닫아야 할 지 알고 있을 것 같습니다.그럼 commit()할 때난 rollback()할 때 그냥 닫거나 롤백하면 될텐데, 왜 status가 필요한가요?

아래처럼 TimeUnit이 적용되지 않아서,구글링하여 maven 디펜던시 추가 등등 해보았지만 안됩니다.혹시나 다른 방법이 있는지 궁금해서 문의드려봅니다. java는 17입니다.    

안녕하세요! 사소한 질문이지만 3.5강 args 강의를 듣다 궁금증이 생겨서 질문드려요 쿠버네티스 yaml 파일 내 command는 docker에서는 Entrypoint와 같고 args는 Cmd와 동일하다고 하셨는데 docker에서 cmd의 경우 docker run 명령어 마지막에 인자값을 넣으면 빌드 파일에 정의된 CMD의 명령어가 아닌 인자값에 전달된 명령어로 실행이 되는걸로 알고 있어요 그래서 3.5/multiple-command-w-args.yaml에 있는 파일의 인자값을 변경해보려고 아래와 같이 시도를 해봤어요 [root@m-k8s 3.5]# k apply -f multiple-command-w-args.yaml echo run kkk\ echo add ccc\ sleep 111error: Unexpected args: [echo run kkk echo add ccc sleep 111] [root@m-k8s 3.5]# k apply -f multiple-command-w-args.yaml echo run kkk && echo add ccc && sleep 111error: Unexpected args: [echo run kkk] [root@m-k8s 3.5]# k apply -f multiple-command-w-args.yaml echo run kkkerror: Unexpected args: [echo run kkk] 그런데 위와 같이 'Unexpected args' 와 같은 오류가 발생이 됐어요 command와 args가 docker 와는 다르게 동작이 되는걸까요? 만약 docker와 동일하다면 multiple-command-w-args.yaml파일에서 args의 인자값을 전달하려면 전달 방식이 어떻게 될까요? 

갱신된 강의자료에도 나와 있듯이, fetchResult, fetchCount 등의 메소드는 deprecated 예정입니다. 또한 해당 메소드는 Page 타입을 반환하기 때문에 Page 타입을 직접적으로 조작해야 한다는 제약이 있습니다. 이걸 잘 쓰면 되는데, Page 의 시작번호 등 제약도 있어서 저는 회사에서 Page 를 따로 만들어서 사용하거든요. 그래서 search 메소드와 count 메소드는 항상 분리하고 있습니다.2. 그런 점에서 count 만 최적화하는 로직만 베껴서 만든 최적화 메소드입니다.실제로 count 구문을 실행하기 위한 메소드입니다. 필요에 따라서 public 으로 만들어도 될 것 같네요. // count 실행 메소드 private Long countByCond(MemberSearchCond cond) { return query .select(member.countDistinct()) .from(member) .where( usernameEq(cond.getUsername()), teamNameEq(cond.getTeamName()), ageGoe(cond.getAgeGoe()), ageLoe(cond.getAgeLoe()) ) .fetchOne(); } 최적화 로직을 베낀 메소드입니다. 스프링 데이터 JPA 는 아래 코드와 같이 page, size 값이 null 이 아니고, 적절한 범위에 있는지를 판단하여 isPaged 라는 분기를 만듭니다. 참고로 코드를 분석하면서 내린 뇌피셜이니 혹시 틀리다면 말씀해주세요. page 가 0 이 아니라 1 부터 시작하는 건 제 취향입니다. 회사에서 그렇게 쓰고 있거든요. 필요에 따라 0 부터 시작하도록 바꾸는 건 어렵지 않을 것 같습니다.public Long countByCondOptimization(List<?> content, MemberSearchCond cond, Long page, Long size) { boolean isPaged = page != null && size != null && page > 0 && size > 0; long offset = isPaged ? (page - 1) * size : 0L; long contentSize = content.size(); if (!isPaged || offset == 0) { if (!isPaged || size > contentSize) { return contentSize; } return this.countByCond(cond); } if (contentSize != 0 && size > contentSize) { return offset + contentSize; } return this.countByCond(cond); } 이렇게 하여 count 쿼리를 리스트 조회 쿼리와 분리하여 재사용성을 높이면서, 성능도 최적화할 수 있습니다.감사합니다.

jpa 로그의 포맷처럼 줄바꿈을 넣으면서, 동시에 ? 자리에 바인딩 파라미터를 넣는 코드입니다. P6Spy 1.8.1, Spring Boot 2.7.x, 마리아DB 10.1.x 사용했습니다.application.properties 에서 JDBC 드라이버나 URL 에 P6Spy 를 추가하면 로그가 2번 출력될 수 있으니 주의하세요. 아래처럼 P6Spy 관련 드라이버? 코드? 가 포함되지 않도록 하시면 됩니다.# datasource spring.datasource.url=jdbc:mariadb://localhost:3306/YOUR_SCHEMA spring.datasource.username=YOUR_USERNAME spring.datasource.password=YOUR_PASSWORD # p6spy log logging.level.p6spy=info decorator.datasource.p6spy.enable-logging=true 로그의 포맷을 실질적으로 꾸미는 구현 클래스입니다. 추가 정보는 실행시간 제외하고는 뺐는데, 필요하시면 추가하시면 됩니다.  import com.p6spy.engine.logging.Category; import com.p6spy.engine.spy.appender.MessageFormattingStrategy; import org.hibernate.engine.jdbc.internal.FormatStyle; import java.util.Locale; public class P6SpyFormatter implements MessageFormattingStrategy { private static final String NEW_LINE = "\n"; private static final String TAP = "\t"; private static final String CREATE = "create"; private static final String ALTER = "alter"; private static final String DROP = "drop"; private static final String COMMENT = "comment"; @Override public String formatMessage(int connectionId, String now, long elapsed, String category, String prepared, String sql, String url) { if (sql.trim().isEmpty()) { return formatByCommand(category); } return formatBySql(sql, category) + getAdditionalMessages(elapsed); } private static String formatByCommand(String category) { return NEW_LINE + "Execute Command : " + NEW_LINE + NEW_LINE + TAP + category + NEW_LINE + NEW_LINE + "----------------------------------------------------------------------------------------------------"; } private String formatBySql(String sql, String category) { if (isStatementDDL(sql, category)) { return NEW_LINE + "Execute DDL : " + NEW_LINE + FormatStyle.DDL .getFormatter() .format(sql); } return NEW_LINE + "Execute DML : " + NEW_LINE + FormatStyle.BASIC .getFormatter() .format(sql); } private String getAdditionalMessages(long elapsed) { return NEW_LINE + NEW_LINE + String.format("Execution Time: %s ms", elapsed) + NEW_LINE + "----------------------------------------------------------------------------------------------------"; } private boolean isStatementDDL(String sql, String category) { return isStatement(category) && isDDL(sql.trim().toLowerCase(Locale.ROOT)); } private boolean isStatement(String category) { return Category.STATEMENT.getName().equals(category); } private boolean isDDL(String lowerSql) { return lowerSql.startsWith(CREATE) || lowerSql.startsWith(ALTER) || lowerSql.startsWith(DROP) || lowerSql.startsWith(COMMENT); } } 5. 아래 코드가 중요한데, 위 4에서 만든 포맷을 적용하는 시점을 알려주기 위해 만드는 JDBC 이벤트 리스너입니다. 어떤 블로그나 포럼에서는 포맷 적용 시점을 @PostConstruct 로 하던데, 그렇게 하면 테이블 create, drop 시점에 적용이 안 돼서 그렇게 하면 안 되고, 아래와 같이 Connection 이 생성되자마자 적용하면 됩니다.  import com.p6spy.engine.common.ConnectionInformation; import com.p6spy.engine.event.JdbcEventListener; import com.p6spy.engine.spy.P6SpyOptions; import java.sql.SQLException; public class P6SpyEventListener extends JdbcEventListener { @Override public void onAfterGetConnection(ConnectionInformation connectionInformation, SQLException e) { P6SpyOptions.getActiveInstance().setLogMessageFormat(P6SpyFormatter.class.getName()); } }  이렇게 2개의 구현 클래스를 만들었으면, 아래와 같이 Bean 으로 등록해주기만 하면 설정 끝입니다. import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; @Configuration public class P6SpyConfig { @Bean public P6SpyEventListener p6SpyCustomEventListener() { return new P6SpyEventListener(); } @Bean public P6SpyFormatter p6SpyCustomFormatter() { return new P6SpyFormatter(); } }

강의에서는 Query DSL 4.x 버전이어서 제네릭 없는 예제 코드인 것 같은데, 제가 올리는 버전은 5.0 버전이어서 차이가 있음을 감안해주세요.정렬 조건을 하나만 추가하는 코드입니다. 정렬 조건을 여러 개 추가하려면 반복문을 돌면서 JPAQuery 를 동적으로 확장해나가면 됩니다. // 페이징하는 메소드에서 사용 private Expression<? extends Comparable<?>> specifyMemberProperty(String prop) { prop = prop == null ? "" : prop.toLowerCase(); if (prop.equals("username")) { return member.username; } if (prop.equals("age")) { return member.age; } return member.id; }  // 페이징하는 메소드 // ... .orderBy(new OrderSpecifier<>("desc".equalsIgnoreCase(dir) ? Order.DESC : Order.ASC, specifyMemberProperty(prop))) .fetch(); --저는 일단 이렇게 만들어봤는데, 다른 분께서 더 나은 코드, 더 빠른 코드가 있다면 저한테도 알려주세요.감사합니다.

36 번라인이구요 This material API is experimental and is likely to change or to be removed in the future.위와 같은 경고메세지가 뜨네요 ...

안녕하세요! 강의 보다가 궁금한 사항이 있어서 질문드립니다!ref로 정의한 데이터와 shallowRef에 대한 데이터 설명주실때,shallowRef에 대한 데이터의 속성은 변경되지 않는다고 하셨는데요.devtools로 shallowRef데이터의 속성을 변경하고 ref 데이터의 속성을 변경하니까 두 속성이 같이 변경되더라구요.. 혹시나 오타인가 하고 찾아봤는데 오타는아닌거같아요 ㅠㅠㅠ..하나의 속성이 변경되면 변경안되는 속성들도 변경되는걸까요? 이부분에 대해 설명부탁드립니다!
