20장. log

초기 로그 구성이 etc/org.ops4j.pax.logging.cfg 에서 로드됩니다.

이 파일은 표준 Log4j2 구성 파일입니다.

다양한 Log4j2 요소가 있습니다.

파일에 직접 고유한 초기 구성을 추가할 수 있습니다.

기본 구성은 다음과 같습니다.

기본 구성은 파일 appender를 사용하여 INFO 로그 수준으로 ROOT 로거를 정의합니다. 로그 수준을 Log4j2 유효한 값으로 변경할 수 있습니다. 가장 상세 정보에서 최소 상세 정보까지 TRACE, DEBUG, INFO, ERROR 또는 FATAL을 지정할 수 있습니다.

이를 활성화하려면 stdout appender를 rootLogger 에 추가해야 합니다.

log4j2.rootLogger=INFO, out, stdout, osgi:*

log4j2.appender.jdbc.cs.lazy = true
