[LogBack] Could NOT find resource [logback-test.xml]

Spring Boot로 개발을 시작하면서, Logback 을 Default Logger 로 사용하게 되는데..

logback.xml 만을 두면

아래와 같은 메시지가 보여집니다.

16:40:00,492 |-INFO in ch.qos.logback.classic.LoggerContext[default] - Could NOT find resource [logback-test.xml]
16:40:00,492 |-INFO in ch.qos.logback.classic.LoggerContext[default] - Found resource [logback.xml] at [file:/C:/project/workspace/springboot/target/classes/logback.xml]

16:40:00,580 |-INFO in ch.qos.logback.classic.joran.action.ConfigurationAction - Setting ReconfigureOnChangeTask scanning period to 30 seconds

별건 아닌데.. 이런거에 신경쓰이는 저이기 때문에..

해결 방법을 찾아봤습니다.

1. logback-test.xml 파일로 옮겨가면 됩니다.

logback.xml 파일을 logback-test.xml 파일로 사용하면 된다는 뜻 입니다.

16:43:03,514 |-INFO in ch.qos.logback.classic.LoggerContext[default] - Found resource [logback-test.xml] at [file:/C:/project/workspace/springboot/target/classes/logback-test.xml]
16:43:03,594 |-INFO in ch.qos.logback.classic.joran.action.ConfigurationAction - debug attribute not set
16:43:03,600 |-INFO in ch.qos.logback.classic.joran.action.ConfigurationAction - Will scan for changes in [file:/C:/project/workspace/springboot/target/classes/logback-test.xml] 
16:43:03,600 |-INFO in ch.qos.logback.classic.joran.action.ConfigurationAction - Setting ReconfigureOnChangeTask scanning period to 30 seconds

없어졌죠..

2. logback.xml 을 logback-spring.xml 로 변경하면 됩니다.

logback-test.xml  파일을 찾았다라는 말도 없이 읽어 집니다.

logback-spring.xml 를 사용하면 Spring Boot 사용 시 좀 더 추가적인 기능을 사용할 수 있다고 합니다.
