[스프링4 MVC REST예제]Spring4 MVC RESTFul웹서비스,스프링프레임워크4,RestController 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 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. <pom.xml> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">   <modelVersion>4.0.0</modelVersion>   <groupId>org.springframework.samples.service.service</groupId>   <artifactId>spring4rest</artifactId>   <version>0.0.1-SNAPSHOT</version>   <packaging>war</packaging>        <properties> <!-- Generic properties --> <java.version>1.6</java.version> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding> <!-- Web --> <jsp.version>2.2</jsp.version> <jstl.version>1.2</jstl.version> <servlet.version>2.5</servlet.version> <!-- Spring --> <spring-framework.version>4.0.2.RELEASE</spring-framework.version> <!-- Hibernate / JPA --> <hibernate.version>4.2.1.Final</hibernate.version> <!-- Logging --> <logback.version>1.0.13</logback.version> <slf4j.version>1.7.5</slf4j.version> <!-- Test --> <junit.version>4.11</junit.version> </properties> <dependencies> <!-- Spring MVC --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>${spring-framework.version}</version> </dependency> <!-- Other Web dependencies --> <dependency> <groupId>javax.servlet</groupId> <artifactId>jstl</artifactId> <version>${jstl.version}</version> </dependency> <dependency> <groupId>javax.servlet</groupId> <artifactId>servlet-api</artifactId> <version>${servlet.version}</version> <scope>provided</scope> </dependency> <dependency> <groupId>javax.servlet.jsp</groupId> <artifactId>jsp-api</artifactId> <version>${jsp.version}</version> <scope>provided</scope> </dependency> <!-- Spring and Transactions --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-tx</artifactId> <version>${spring-framework.version}</version> </dependency> <!-- Logging with SLF4J & LogBack --> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-api</artifactId> <version>${slf4j.version}</version> <scope>compile</scope> </dependency> <dependency> <groupId>ch.qos.logback</groupId> <artifactId>logback-classic</artifactId> <version>${logback.version}</version> <scope>runtime</scope> </dependency> <!-- Hibernate --> <dependency> <groupId>org.hibernate</groupId> <artifactId>hibernate-entitymanager</artifactId> <version>${hibernate.version}</version> </dependency> <!-- Test Artifacts --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-test</artifactId> <version>${spring-framework.version}</version> <scope>test</scope> </dependency> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>${junit.version}</version> <scope>test</scope> </dependency> </dependencies> </project> 3.
