tomcat 기본 설정값 그대로 사용하다보면
IDE 에서 코드를 생산하는 과정에서 로그를 확인할때
가독성이 떨어지기도 하고
서버 로그를 확인할때
영양가없는 로그가 쌓이는 경향이 있음.
server 단이 문제가 아니라면
application 단에서는 warning 단계로 잡아도 충분한듯.
따라서 평소에 로그레벨을 info보다 높게 잡아서 warning 정도로 해놓다가
시스템 이상이 발견될때 한시적으로 낮춰서 디버깅하는게 나아보임.

IDE 에서의 설정
eclipse 나 intellij 에서 하단 console 로그를 확인해보면
매번 tomcat run 할때마다 거슬리는 문구가 보인다.

이는 tomcat 설치후 [tomcat 설치경로]/conf/server.xml 파일의 기본값에
<수정 전>
<!-- Define an AJP 1.3 Connector on port 8009 -->
<Connector port="8009" protocol="AJP/1.3" redirectPort="443" secretRequired="true"/>
로 되어있기 때문인데
보다시피 AJP 를 사용한다고 했으나 프로젝트에서 해당 설정이 없기때문에 발생하는 메세지라고 한다.
AJP 설정은 보안설정상 false 하지 않는 것이 좋으나
개발환경에서는 false로 해도 아무문제 없으니 해당 값을 false로 변경한다.
<수정 후>
<!-- Define an AJP 1.3 Connector on port 8009 -->
<Connector port="8009" protocol="AJP/1.3" redirectPort="443" secretRequired="false"/>
이후
IDE에서 tomcat을 rerun 할때 해당 메세지가 사라진 것을 알수 있다.
