어느날 갑자기
잘 WAR 배포 되던 사이트에서
tomcat 시작시 오류가 발생했습니다.
물론 간헐적으로 종종 있었지만,
아에 시작이 안되는 오류가 발생한것은 처음이었지요

-------------------------------------------------------------
해당 원인
1. Tomcat JMX(Java Management Extensions) 사용 + STS JMX 사용 = 2개 포트 중복으로 인한 충돌 발생
2. Local 개발 환경에서는 Tomcat을 사용하지 않아 발생하지 않음
3. 개발 서버에서는 Startup 시 Tomcat JMX가 먼저 부팅되는 경우(그동안) 정상적으로 UP이 되었으나
언젠가는 발생해야 하는 문제였음.
해결 방법
1. STS 에서 사용하는 JMX 사용하지 않기(Tomcat만 사용하기)
application.properties 설정 변경 방식 => 이 방식 설정 (우리는 JMX를 쓰지 않음, 만약 쓰고 싶다면 2번 해결 방식 참고)
2. STS에서 사용하는 JMX 포트 변경
There are a few things we could do to avoid the error. We could open the editor again and change the JMX port as well, or we could disable ‘Live Bean Support’. But probably we don’t really want to run more than one copy of our app in this scenario. So we should just stop the already running instance before launching a new one. As this is such a common thing to do, STS provides a Relaunch Toolbar Button for just this purpose. Click the Button, the running app is stopped and restarted with the changes you just made to the Launch Configuration now taking effect. If it worked you should now have a 404 error page at http://localhost:8888 instead of 8080. (Note: the Relaunch button won’t work if you haven’t launched anything yet because it works from your current session’s launch history. However if you’ve launched an app at least once, it is okay to ‘Relaunch’ an app that is already terminated)

application.properties 추가 내역
============================================================================================================================
# Prevent Spring from automatically exposing beans to JMX. Tomcat automatically creates an MBean when setting the
# JNDI data source, and an error gets thrown if spring then tries to add the data source MBean itself.
# 번역 : Spring이 자동으로 Bean을 JMX에 노출시키는 것을 방지한다. Tomcat은 JNDI 데이터 소스를 설정할 때 자동으로 MBean을 만들고, 스프링이 데이터 소스 MBean 자체를 추가하려고하면 오류가 발생합니다.

# org.springframework.jmx.export.UnableToRegisterMBeanException 예외처리용

Java Management Extensions 의 약자로 각종 프로그램/장치 등을 모니터링/관리 하기 위한 API 입니다.
