C3P0 log4j:WARN No appenders could be found for logger (com.mchange.v2.log.MLog)

SSH를 학습하는 과정에서 로그를 설정하고 SLF4J와 LOG4J를 조합하여 데이터베이스 연결 탱크로 c3p0을 만들고 서버를 시작하면 다음과 같은 경고 메시지가 나타납니다.
 
 log4j:WARN No appenders could be found for logger (com.mchange.v2.log.MLog).  log4j:WARN Please initialize the log4j system properly.
 
스프링 설정 감청기가 Log4j 설정 감청기보다 먼저 실행되었기 때문에 해결이 간단합니다. Log4j 설정을 스프링 설정 전에 ok했습니다.
