welcom-file-list란, 디렉토리의 기본 웹 페이지이다.

클라이언트가 서블릿 이름을 생략하고 디렉토리까지만 지정해서 요청한다면 웹 서버는 해당 디렉토리에서 웰컴 파일을 찾아서 응답한다.

 

1. 여기서 servlet 태그에 작성하는 dispatcher는 web.xml에서 읽어줄 명을 작성해주는 것(?) 이부분잘모르겠다.

async-supported 는 비동기처리를 위한 태그인것으로 보인다.

 <servlet>
    <servlet-name>dispatcher</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <async-supported>true</async-supported>
  </servlet>
