ConsoleAppender

- 콘솔에 로깅 설정

 

RollingFileAppender

- 파일 로깅 설정

 

<logger name="{패키지명}"    level="{로깅 레벨}" />

- 해당 패키지 경로에는 설정 로깅 레벨 이상만 로깅 진행 

 

 <root level="INFO"> </root>

- 최상위 패키지에 기본적으로 적용되는 것 

 

Level 

- trace < debug < info < warn < error

 

ex) <logger name="com.spring.org" level="TRACE"> 

        <appender-ref ref="webFileAppender" />

    </logger>

 

- com.spring.org 패키지에는 TRACE 레벨 이상만 로깅하며  파일 로깅을 진행한다.

간단하게 HomeController에 로깅 테스트 진행 

 

 

* 해당 패키지 명은 com.spring.org

 

실행 이후 Console 결과  

실행 이후 C:\logs 확인 결과
