[ 게시판 v.1 ] xml 설정

어찌 어찌 톰캣 다운 받고 다 준비 했는데 일단 xml 설정이 가장 고된거 같다.

 

그래도 처음이 힘들지 한번 길을 잘 닦아 놓으면 그 다음은 고속도로 인거 같다.

설정으로 빡치는 사람 전부 다 힘내기.. :(

 

아래 코드들은 내가 만든 게시판 설정 그대로 이다.

web.xml

• web.xml 파일은 웹 어플리케이션의 배포 설명자로, 각 어플리케이션의 환경을 설정하는 역할을 한다
• 서버가 처음 로딩될 때 읽어들이고, 해당 환경설정에 대해 tomcat에 적용하여 서버를 시작한다.
• dispatcherServlet 설정, db설정과 같은 서브릿 설정에 대한 내용,
• listener, filter 설정 및 welcome file list, error page 처리,
• mome type매핑, session 의 유효시간 설정, servlet context의 초기 파라메터 설정 등이 있다.
• web.xml파일은 맨 처음 <web-app> 태그로 시작되고,
• xmlns 네임스페이스로 xml schema for java EE Deployment Descriptors 파일이 존재하는 위치를 선언해주고 있다.

servlet-context.xml

• servlet에서 보듯이 요청과 관련된 객체를 정의합니다.

root-context.xml

• servlet-context.xml 과는 반대로 view와 관련되지 않은 객체를 정의합니다
• 따라서 Service, Repository(DAO), DB등 비즈니스 로직과 관련된 설정을 해줍니다.
• JSP와 관련없는 객체(bean)을 설정합니다.(service, repository)
• 비지니스 로직을 위한 설정을 합니다.
• 외부 jar 파일등으로 사용하는 클래스는 <bean>태그를 이용하여 작성합니다.
• 공통 빈을 설정합니다.

• 이 설정은 아무것도 건들지 않았다.
