[오라클자바커뮤니티실무교육]Spring4 MVC HelloWorld(스프링프레임워크4 MVC Helloworld, 스프링 튜토리얼, Spring Maven, WEBMVC)
템플릿을 다운받아서 봐도 되겠지만 직접 만들어 보자.
0. 전체 프로젝트 파일 구성은 아래 그림과 같다.
1. File -> New -> Project -> Spring -> Spring Project -> Simple Spring Web Maven
project name은 spring4로 하자.
2. pom.xml에서 스프링 버전을 4로 변경하자.(기본적으로 3.2로 되어 있을 것이다)
<spring-framework.version>4.0.2.RELEASE</spring-framework.version>
그런다음 프로젝트에서 마우스 우측버튼 -> maven -> update project를 실행하여 spring4 관련 jar 파일을 내려받자.
