[1.개발환경의 설정]2. 스프링 MVC 프로젝트 템플릿의 구조

Navigator로 본 화면 

Maven의 구조는 크게 

-src: 실제 구현하는 소스

test폴더는 main에 있는 소스로 테스트한다.

resource: 자바가 아닌 파일들 다 넣기(ex: 설정파일)

webapp > resouce를 src>resource에 다 넣기도 한다.

-target: 메이븐을 통해 컴파일 되어 떨어지는 소스

web-inf>classes: 컴파일되면 이 폴더로 다 들어옴

ex00 아래의 디렉토리들을 '프로젝트 레벨'이라고 한다

pom.xml

메이븐 파일

groupId: 서버

artifactId: 업무 구분

*artifactId 가 context 경로가 된다

실행을 하고 나면 제일 먼저 web.xml 확인

 

root-context.xml을 쓰기 위하여는 listener를 사용하여야 한다.

beans:property 속성과 맞물려 동작함
