==== 서버설정 ====
  * Remote 포트 지정 : ''1043''
  * ''CATALINA_OUT''에 다음 옵션을 지정한다.<code sh>
-agentlib:jdwp=transport=dt_socket,address=1043,server=y,suspend=n
</code>
  * 재시작

==== IntelliJ 설정 ====
  * **Run/Debug Configurations -> Tomcat Server -> Remote**
  * **Startup/Connection -> Debug** 탭에서

    * Port : ''1043'' 지정.

  * **Debug** 모드에서 코드의 Line이 아닌 **메소드 선언부에 Break Point**를 걸면 엄청난 성능 저하가 발생한다.
  * 메소드 선언부 Break Point는 피하라.
