====== Logback logging ======
===== 개요 =====
배치 처리시 로깅 처리를 위해 log4j2를 지원하고 있지만 경량화된 로깅 처리를 위해 Logback 로깅 처리를 지원한다.\\

===== 설명 =====

==== Logback pom.xml 설정 ==== 
log4j, commons-logging 관련 라이브러리를 exclusion 처리하고, Logback 라이브러리를 등록한다.

==== SQLite 사용 ==== 
logback 사용을 위해 logback.xml를 설정이 선행 되어야 한다.\\
설정관련 자세한 사항을 아래 링크 참고 \\
[[https://logback.qos.ch/manual/introduction.html]]
<code xml>
<!-- 설정 예시 -->
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
	<appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
