[Spring] STS ....

스프링 설정 파일 중 봐야 할 것들,

• servlet-context.xml
• root-context.xml
• web.xml
• pom.xml

이다.

• web.xml 은 서버에서 시작지점이 된다고 보면 된다
• servlet-context.xml은서블릿 영역의 설정을 해주는 부분으로 A라는 관리자 서블릿과 b라는 사용자 서블릿이 있을 때 서로의 접근을 차단해주어야 하지만, DB는 공유해야 하기 때문에 서블릿을 A,B로 구분하고 root-context.xml에서 공용으로 사용하는 DB를 설정해 주는것
• pom.xml 은 메이븐 관리해주는 곳...(여긴 잘 모르겠음)
• root-context.ml 은 프로젝트 의 영역을 설정
