1. Spring Legacy Project를 생성
2. Spring MVC Project의 구조
   • 
   1. 컨트롤러와 서비스, DAO, Mapper XML, logging XML파일로 채워질 Java Source 디렉토리
   2. 서블릿설정파일, JSP페이지파일, js파일, 각 종 이미지 및 관련파일등이 채워질 Servlet관련 디렉토리
   3. WEB-INF폴더에 있는 web.xml파일로 가봅시다.

1. contextConfigLocation
   • bean의 설정파일
   • DB에 대한 bean
2. appServlet
   • DispatcherServlet의 설정파일
   • MVC구조중 C에 해당하는 설정파일로 맵핑된 jsp파일에 맞는 컨트롤러를 찾아주는 역할을 합니다.
3. servlet-mapping
   • url-pattern을 지정(보통 *.do, *.action등을 사용하죠)
4. filter
5. listener

• pom.xml은 Spring에 내포되어 있는 Maven설정파일입니다.
• root-context.xml
