1. 新建一个spring项目

使用IDEA新建spring 的maven项目，这是标准的企业做法。File -> New Project，选择Maven项目，并确保jdk在1.7以上。

输入GroupId和ArtifactId后，在pom.xml中填入spring framework的依赖。

<properties>
        <file.encoding>UTF-8</file.encoding>
        <spring.version>4.2.8.RELEASE</spring.version>
    </properties>

    <dependencies>
    <!-- spring 依赖-->
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-beans</artifactId>
            <version>${spring.version}</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-context</artifactId>
            <version>${spring.version}</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-context-support</artifactId>
            <version>${spring.version}</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-jdbc</artifactId>
            <version>${spring.version}</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-webmvc</artifactId>
            <version>${spring.version}</version>
        </dependency>
    </dependencies>
