[Spring]logback.xml 로 프로파일 별 로그 남기기..

1. 프로젝트 생성.

이클립스 기준, Spring MVC Project 프로젝트 생성

2. 메이븐 빌드-배포가 아닌 단순 톰캣 서버 실행..

- pom.xml 에 dependency 추가

<dependency>
			<groupId>ch.qos.logback</groupId>
			<artifactId>logback-classic</artifactId>
			<version>1.0.13</version>
			<exclusions>
				<exclusion>
					<groupId>org.slf4j</groupId>
					<artifactId>slf4j-api</artifactId>
				</exclusion>
			</exclusions>
			<scope>runtime</scope>
		</dependency>
<!--logback.xml 에서 프로파일 별 분기를 위한 if condition 구문을 쓸 수 있게 한다.-->
		<dependency>
			<groupId>org.codehaus.janino</groupId>
			<artifactId>janino</artifactId>
			<version>3.0.8</version>
		</dependency>

3. logback.xml

-    log4j.xml 파일을 logback.xml 로 변경

- logback.xml

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

</configuration>

3. 서버 구동

Run Configuration > VI arguments   -Dspring.profiles.active='프로파일'   에 옵션 추가 후 실행
