[Spring Boot] logback 간단 설정

새로 세팅할 때마다 찾아보는거 귀찮아서

그래서! 정리해봄

resources/logback.properties 파일 추가

log.file.path=C:/logs/

resources/logback.xml 파일 추가

<?xml version="1.0" encoding="UTF-8"?>
<configuration>

    <!-- properties 파일 지정 -->
	<property resource="logback.properties"/>

    <!--로그 파일 저장 위치-->
    <property name="LOGS_PATH" value="${log.file.path}"/>

    <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
        <layout class="ch.qos.logback.classic.PatternLayout">

    </logger>
    <root level="INFO">
        <appender-ref ref="STDOUT" />
    </root>
</configuration>

로그 찍어보기

public static Logger logger = LoggerFactory.getLogger(ClassName.class);
...
...
...
logger.trace("trace -- Hello world.");
logger.debug("debug -- Hello world.");
logger.info("info -- Hello world.");
logger.warn("warn -- Hello world.");
logger.error("error -- Hello world.");		

파일도 제대로 생성 ㄳ
