Spring(1)_설정파일

web.xml - 서블릿( 필터 포함 ) 을 등록 (정의 및 어떤 요청에 대해 작동시킬 것인지 url mapping )

: 여기서 DispatcherServlet 은 스프링 컨테이너를 생성하며 MVC에서 Front Controller 역할을 수행한다

: 주로 Encoding Filter 와 Dispatcher Servlet을 등록함

servlet-context.xml

: 스프링 컨테이너가 매번 클라이언트의 요청을 받을 때 어떻게 처리할건지 "전체적인 구조" 를 설정한 파일

: DispatcherServlet Context: defines this servlet's request-processing infrastructure

• js, css 파일을 어디서 읽을 것인지
• view를 읽을때 어떻게 읽을것인지 (prefix, suffix 설정)
• DispatcherServlet이 요청에 맞는 컨트롤러를 찾고 , 컨트롤러가 보낸 응답을 알맞게 변형해주는 객체들 (HandlerMapping, HandlerAdapter)을 등록한다 (annoation-drriven)
• @annotation이 명시된 파일들을 어디서 읽을 것인지 base-package 설정 등

root-context.xml

: Root Context: defines shared resources visible to all other web components

: 주로 DB연동과 관련한 bean들을 등록한다 (JDBC : DataSource / MyBatis : SqlSessionFactoryBean)

: 클라이언트의 요청과는 관련이 없는, Back-end 에서만 필요한 설정들을 한다.
