Spring MVC | Spring 설정 파일 분리 *.servlet.xml

Spring 설정 파일 분리 - dispatcher-servlet.xml

하나로 된 파일을 여러개의 xml로 나누기

프로젝트를 여러사람이 만들경우 동기화할 경우 문제가 생겨 각자 맡은 역할을 나눠서 작업하기 위해서 나눈다.

혼자 만들 경우에도 나눠서 설정을 해주는게 좋다.

설정 적용시키기 web.xml

init-param 사용

listener class 사용 - tomcat이 실작되거나 끝날때 세션이 시작되거나 끝날때 이벤트 처리를 위해 사용

 

<load-on-startup> - tomcat이 시작될때 servlet을 laod하고 싶을 경우 숫자는 우선순위를 나타낸다.

<async-supported> - 비동기적으로 load되는 것을 원할 경우
