[SPRING] Log4j2가 Spring 부트 로깅 구현을 찾을 수 없음
SPRINGLog4j2가 Spring 부트 로깅 구현을 찾을 수 없음
이 오류가 봄 부팅으로 log4j2를 사용하려고합니다.
ERROR StatusLogger Log4j2 could not find a logging implementation.
Please add log4j-core to the classpath. Using SimpleLogger to log to the console...
이 가이드를 따라갔습니다 : http://docs.spring.io/spring-boot/docs/current/reference/html/howto-logging.html#howto-configure-log4j-for-logging - 또한 https://logging.apache.org/log4j/2.x/maven-artifacts.html의 두 가지 log4j2 종속성
내 의존성 : 나무는 다음과 같이 보입니다.

어떤 추측인가? 나는 Spring Tool Suite와 Maven Spring-Boot Plugin 내에서 실행을 시도했다.

해결법
-
==============================
1.LogManager.class의 소스 코드를 찾아보고 log4j-core.jar / META-INF에있는 log4j-provider.properties에 LoggerContextFactory가 없다는 것을 알게되었습니다. 따라서 log4j-core.jar / META-INF / log4j-provider.properties 파일을 확인하거나 로컬 저장소에서 log4j-core.jar을 삭제할 수 있습니다.

==============================
2.이 오류 메시지는 log4j-api 모듈이 해당 인터페이스의 구현을 찾거나로드 할 수 없을 때 생성됩니다. 보통 이것은 log4j-core 모듈이 classpath에서 빠져 있지만 의존성 그래프를 보지 않는다는 것을 의미합니다.
이 오류 메시지는 log4j-api 모듈이 해당 인터페이스의 구현을 찾거나로드 할 수 없을 때 생성됩니다. 보통 이것은 log4j-core 모듈이 classpath에서 빠져 있지만 의존성 그래프를 보지 않는다는 것을 의미합니다.
log4j-slf4j-impl 및 log4j-jul 모듈에는 일부 전이 종속성이 있지만 오류 메시지가 발생할 수 있다고 생각하지 않습니다.
더 자세히 조사 할 수있는 한 가지 방법은이 시스템 속성 집합 (-Dorg.apache.logging.log4j.simplelog.StatusLogger.level = TRACE)을 사용하여 응용 프로그램을 다시 시작하는 것입니다. 그러면 log4j 내부 디버그 로깅이 콘솔에 인쇄됩니다.
(일단 구성 파일이로드되면 Log4j2.xml 구성 파일의 시작 부분에
를 설정하여 StatusLogger 출력 레벨을 제어 할 수 있습니다. 그러나 구성 파일은 log4j-core 모듈에 의해로드되고 우리는 아직 안 ...) -
==============================
3.당신의 의존성이 올바른 것 같습니다. 이것은 로깅 프레임 워크로서 log4j2를 사용하는 spring-boot 응용 프로그램을 작동시키는 것입니다.
당신의 의존성이 올바른 것 같습니다. 이것은 로깅 프레임 워크로서 log4j2를 사용하는 spring-boot 응용 프로그램을 작동시키는 것입니다.

-Dlog4j.configurationFile = "conf / log4j2.xml"
포기하지 말고 logback에서 log4j2로 다시 전환하십시오 ...
-
==============================
4.여러 가지 이유가있을 수 있지만 일반적으로 잘못된 JAR (손상됨)이있을 수 있습니다. 저장소에서 JAR을 삭제하고 다시 다운로드하십시오. 문제를 해결할 것입니다.

제 경우에는 Maven 저장소에서 org 폴더를 삭제했습니다. {home} .m2 \ repository \ org.
