Spring4 MVC RESTFul웹서비스,스프링프레임워크4,RestController

0. 전체 프로젝트 파일 구성은 아래 그림과 같다.

1. File -> New -> Project -> Spring -> Spring Project -> Simple Spring Web Maven

project name은 spring4rest로 하자.(프로젝트 이름이 웹사이트의 컨텍스트 명이다.)

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.
