TIP

log4jdbc-log4j2 사용 시 테스트 로그가 많이나와 불편할 경우 src/test/resources/log4.xml 파일 수정

해당 파일 하단 </log4j:configuration> 태그 위 아래의 태그들을 추가해주자.

(자세한 설명은 https://logging.apache.org/log4j/2.x/manual/customloglevels.html 참고)

 

</logger name="jdbc.audit">
</level value="warn" >

</logger name="jdbc.resultset">
</level value="warn" >

</logger name="jdbc.connection">
</level value="warn" >
