강의를 따라한 후 서버를 실행하니까 이렇게 오류가 뜨는데 해결법을 알 수 있을까요..?? 구글링해도 적절한 해결법을 못찾겠습니다 ㅠㅠㅠ

위 문장의 syntax 에러가 아래와 같이 뜨는데 어떻게 해결해야할까요..?ㅜSQL은 MySQL Command Line client 사용했습니다..!

수업자료가 비어있어서 비슷한 문제로 글 올리신분들이 몇 있으시던데,보인다고 하시는 분들이 있으나...저는 수업자료를 다운받으니 폴더가 비어있습니다.

따라치기에 바쁘고 코드를 적으시는데 이해못하면 잘못 듣고있는건가요? 자바 강의는 다 들었는데 뭘하시는지를 모르겠고 따라적기만 하고있습니다..

분명 결과가 에러가 떠야 맞는데... 이상해요 그리고 강사님 화면처럼 결과가 뜨지도 않구요저는 윈도우 쓰고 있는데 이건 운영체제가 달라서 그런건 아닌거같은데... 뭐가 문제일까요?ㅠ

안녕하세요강의 수강 중 프로젝트 폴더를 다른 폴더에 저장하고 싶어서 이동시켰습니다. 그 후 인텔리제이로 프로젝트를 열어보니 폴더가 보이지 않는 오류가 있어 구글링해서 오류를 해결하고자 했는데요. (참고했던 블로그: https://solbel.tistory.com/2712)그 후 다시 확인해 보니 디렉토리 구조도 정상적으로 다 뜨지 않는 것 같고 스프링 프레임워크도 사라진 것 같습니다...ㅠ일반 자바 프로젝트는 폴더 위치를 옮겨도 문제가 생기지 않았는데 스프링 프로젝트만 이런것인지.. 혹시 해결할 수 있는 방법이 있을까요?

 토비님 강의랑 동일하게 설정했는데 동작을 안하네요 지금 @JdbcTest로 해결은 했는데 왜 읽어오지 못하는지 궁금합니다.예전 토비님 책 보면 xml을 읽어와서 빈을 넣어준 걸로 알고 있는데 classes는 어떻게 동작해서 저걸 못읽어오는걸까요?

JPA 기본편 공부하면서 @Embeddded 타입 (내장타입)은 여러 Entity에서 공유하면 안좋다고 배웠는데, Delivery 엔티티 클래스랑, Member 엔티티 클래스에 동시에 사용해도 문제가 없을까요?

Actuator와 cloud bus라는 좋은 기능을 보면서 궁금증이 생겼습니다!이를 통해 자바 어플리케이션을 재시작하지않고 DB 커넥션변경 가능할까요??actuator로 db를 계속 변경 할 수 있으면 너무 좋을 것 같습니다!!

 토비님이랑 같은 의존성 주입 받았는데 전 HikariDataSource라는 class가 존재하지 않습니다. 제가 잘못한게 있을까요

 이니셜라이저는 다음처럼 구성했고인텔리제이 커뮤니티 에디션을 사용해서 프로젝트를 열고 -Ddebug 를 주고 실행했을 때콘솔 결과는 다음과 같습니다.오전 8:52:26: Executing ':SpringbootAcApplication.main()'...> Task :compileJava UP-TO-DATE> Task :processResources

 안녕하세요. 수강생입니다. 다름이 아니라 메뉴 등록시 조회가 되고 어쩔 땐 등록페이지로 갑니다. http://localhost:8080/menu?start_date=&end_date=&name=&kind=ALL 원인을 못찾겠어서 문의드립니다. 감사합니다.

해당 에러를 고치기 위해 세팅의 자바 컴파일러 버전을 11로 바꾸었는데 이렇게 진행하여도 괜찮은가요??

 안녕하세요. 처음부터 열심히 강의를 듣고 있는 수강생입니다. 다름이 아니라 저는 STS, Gradle-Groovy로 진행을 하고 있는데요.해당 강의에서 logback을 설정하니 엄청나게 많은 로그가 나와서 쿼리로그만 나올 수 있게 할 수 있는지에 대해 문의드립니다.  <일부분 로그만 복사> WebSocketServletAutoConfiguration.UndertowWebSocketConfiguration: Did not match: - @ConditionalOnClass did not find required class 'io.undertow.websockets.jsr.Bootstrap' (OnClassCondition) XADataSourceAutoConfiguration: Did not match: - @ConditionalOnClass did not find required class 'javax.transaction.TransactionManager' (OnClassCondition)Exclusions:----------- NoneUnconditional classes:---------------------- org.springframework.boot.autoconfigure.context.ConfigurationPropertiesAutoConfiguration org.springframework.boot.autoconfigure.context.LifecycleAutoConfiguration org.springframework.boot.autoconfigure.context.PropertyPlaceholderAutoConfiguration org.springframework.boot.autoconfigure.availability.ApplicationAvailabilityAutoConfiguration org.springframework.boot.autoconfigure.info.ProjectInfoAutoConfiguration     /Sailing/src/main/resources/logback-spring.xml<?xml version="1.0" encoding="UTF-8"?><configuration> <appender name="console" class="ch.qos.logback.core.ConsoleAppender"> <encoder> <Pattern>[%d{yyyy-MM-dd HH:mm:ss}:%-3relative] [%thread] %-5level %logger{36} - %msg%n</Pattern> </encoder> </appender> <!-- Logback 은 5단계의 로그 레벨을 가진다. 심각도 수준은 off > Error > Warn > Info > Debug > Trace 이다. --> <!-- name은 package 이름 --> <logger name="com.boot.sailing" level="Info"/> <root level="Debug"> <appender-ref ref="console"/> </root></configuration> 감사합니다.

( org.hibernate.LazyInitializationException :  failed to lazily initialize a collection of role 예외, 트랜잭션을 닫을 시점에 entity manger is null (AbstractItemCountingItemStreamItemReader.close)예외가 발생하였는데 이것과 관련되어있는지도 궁금합니다...!)2) 멀티스레드 환경의 chunk 배치 멀티스레드 환경에서 chunk 배치를 사용하는 경우 JpaPagingItemReader를 사용한다고 가정하였을때, '스레드 동기화를 보장'한다는 것에 대해 궁금한데요. 예를 들어, 쓰레드가 5개인 환경에서 조회할 값이 isSample 컬럼이 false인 데이터 100개라고 가정하고 pagingItemReader를 이용해서 offset을 0으로 두고 10개씩 (chunksize = 10, pageSize = 10) 읽고 processor가 isSample 컬럼을 true로 바꾸는 역할을 수행하는 것을 가정합니다. 먼저 1~10번의 아이템을 각각의 1~5번의 스레드가 10개의 각각의 아이템을 할당 받는 과정에서 동기화(중복된 아이템을 스레드가 겹쳐서 읽지 않음)를 이루고 처리후 다음 10개를 읽고 처리하는 과정을 반복한다고 이해하였는데요. 이때, 만약 처음 1~10번의 아이템을 읽고 처리하는 과정에서 한 스레드가 처리과정에서 오랜 시간이 소요되는 병목지점이 발생한다면 commit이 이루어지지 않고, 다음 아이템 11~20번을 읽을때 앞서서 처리되지 않은 아이템을 다시 읽어오고 또다시 병목 지점이 발생할 수도 있고, 결과적으로 같은 아이템을 다른 스레드가 중복으로 처리하게 될 수도 있을 텐데 이럴경우 어떻게 처리가 이루어지는지 궁금합니다. (이런 부분에서는 동기화가 이루어지지 않는 것인지, 제가 이해한 과정이 맞는지도 궁금합니다...!) 3) synchronizeditemstreamreader를 사용하는 경우 lockSynchronizedItemStreamReader를 사용하는 경우에는 동기화를 위해서 쓰레드가 lock을 획득하고 처리하는 과정이 이루어진다면, DB connection의 갯수는 항상 쓰레드의 갯수보다 많게 유지해야 하는 걸까요? ( 작게하면 Connection is not available, request timed out after 오류가 뜨고 있습니다...!)강의 정말 잘 보고 있습니다! 감사합니다 강사님! 

질문에 defer-datasource-initialization: true 추가하라해서 했는데도 안됩니다 

안녕하세요. 정말 유용한 강의 해주셔서 감사드립니다. 인증 처리 관련해서 궁금한점이 있어 질문 드려요!!궁금한점은 로그인 이외 요청에서는,AuthenticationFilter 를 통과하지 않고 진행되는 것인가요?.antMatchers("/**") .hasIpAddress("172.30.1.60") .and() .addFilter(getAuthenticationFilter()); 감사합니다.

구글링 해서 여러가지 방법들을 시도해봤지만 컴파일 에러가 사라지지 않습니다ㅜㅜProject: Gradle-GroovySpring Boot: 3.0.2Java: 17Java Version: openjdk 17.0.6

제가 처음에 json 파일을 아예 잘못된 형식으로 보내는 바람에 kafka sink connector가 fail 상태가 되었었습니다.근데 문제는 이 상태에서 sink connector를 재실행을 해도 source connector랑 sink connector, topic까지 모두 새로 만들어도 계속해서 task에 잘못 요청한 데이터가 남아있어서 아무리 오랜 시간을 기다려도 계속해서 Exception이 발생한 상태가 되어 있습니다..결국 한참을 구글링하면서 찾아보다가 토픽 내에 있는 메세지를 삭제하는 방법을 찾아서 해결했습니다 ㅜㅜ 여기서 제가 궁금한 점은source connector에 잘못된 정보를 보내는 바람에 sink connector가 먹통이 되어버리면 메세지나 토픽 자체를 수동으로 삭제해주는 것 외에는 방법이 없을까요? 구글을 찾아봐도 마땅한 방법을 찾지 못했습니다이건 제가 카프카에 대해 아직 똑바로 이해하지 못해서 나온 질문인데, connector랑 topic까지 모두 따로 만들어도 하나의 sink에서 문제가 생기면 모든 커넥터가 정상적으로 동작하지 않는 게 원래 이런 게 맞는 건지 궁금합니다. 감사합니다.
