1. web.xml
- web.xml은 Was(ex : Tomcat)가 처음 실행할 때 web.xml 파일을 제일 먼저 읽고 거기에 정의된 구성대로 프로젝트를 설정해준다.
- 쉽게 말하자면 내 Spring project의 구성을 설정하는 파일이고 제일 먼저 설정되는 파일
- web.xml 내부에서 spring 관련 설정 파일로 servlet-context.xml, root-context.xml 이 존재

2. servlet-context.xml & root-context.xml
-
- servlet-context.xml
- 요청과 관련된 객체 정의
- dispatcherServlet 관련 설정을 담당하고 보통 spring, java, mvc, bean, servlet 관련 설정들을 여기서 수행한다고 보면된다.
- root-context.xml
- spring 외적인 설정 파일(view와 관련되지 않는 객체 정의)로 servlet-context.xml에서 먼저 찾다가 없으면 여기까지 올라와서 필요한 것을 찾는다.
- Service, Repository(DAO), DB등 비즈니스 로직과 관련된 설정
- servlet-context.xml
