[log4j] log4j 를 설정해보자

기본 commons-logging API를 이용해 Log4J 구현체를 통한 로깅을 해보도록 하자.

우선, 다음 프로퍼티 화일을 클래스패스 (나는 src 폴더에 넣었다. 왜냐... 톰캣에서 새로 디플 할때마다 같이 넣어준다.)에 위치시킨다.

commons-logging.properties

#기본적으로 Log4J 로거를 사용하겠다는 설정.
org.apache.commons.logging.Log=org.apache.commons.logging.impl.Log4JLogger

#설정역시 log4j.properties의 내용을 따르겠다는 설정
log4j.configuration=log4j.properties

뭐 내용은 

# ********** APPENDER ********** 에서 설정한 출력 방식으로

# ********** MAPPING ********** 에서 맵핑해 출력하도록 설정한다.

맵핑시 에러 로깅 수준을 정할 수 있고, 출력 Appender도 맵핑한다.


라이브러리는 알아서 추가한다. 이상. 졸려..
