응용 시스템에서 로그를 남기기 위해 Logback을 사용하는 경우 Properties를 별도의 파일로 분리하여 설정이 가능하다.
■ logback.properties
####################################################### # Logback propertiies # ####################################################### log.dir=d:/temp/logs/batchagent log.level=DEBUG app.log.name=agent_app err.log.name=agent_error max.history=7 max.log.file.size=50MB |
Properties 파일은 key=value로 정의하면 된다.
■ logback.xml

logback.xml 파일에 properties 파일을 <property file="" />를 이용하여 Properties 파일을 읽는다.
Properties 파일에 정의되어 있는 Property를 사용할 때 ${property key}로 사용하면 된다.
