• The JDBC driver provides a database specific implementation of the JDBC API. We use the H2 in-memory database because it makes our example application easier to run.
• The datasource provides database connections to our application. We use the HikariCP datasource because it is the fastest datasource on this planet.
• The JPA Provider implements the Java Persistence API. We use Hibernate because it is the most common JPA provider.
• Spring Data JPA hides the used JPA provider behind its repository abstraction.

First, we can enable the Spring IO Platform by adding the following XML to our POM file:

<dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>io.spring.platform</groupId>
            <artifactId>platform-bom</artifactId>
            <version>1.1.2.RELEASE</version>
            <type>pom</type>
            <scope>import</scope>
        </dependency>
    </dependencies>
</dependencyManagement>

After we have enabled the Spring IO Platform, we don’t have to worry about dependency versions because the Spring IO Platform takes care of that. This means that we can get the required dependencies by adding the following XML to the dependencies section of our POM file:

<!-- Database (H2) -->
<dependency>
    <groupId>com.h2database</groupId>
    <artifactId>h2</artifactId>
</dependency>
<!-- DataSource (HikariCP) -->
<dependency>
    <groupId>com.zaxxer</groupId>
    <artifactId>HikariCP</artifactId>
</dependency>
<!-- JPA Provider (Hibernate) -->
<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-entitymanager</artifactId>
</dependency>
<!-- Spring Data JPA -->
<dependency>
    <groupId>org.springframework.data</groupId>
    <artifactId>spring-data-jpa</artifactId>
</dependency>

自动管理依赖适用于新项目。如果是旧项目，那就手动添加

<!-- Database (H2) -->
<dependency>
    <groupId>com.h2database</groupId>
    <artifactId>h2</artifactId>
    <version>1.4.185</version>
</dependency>
<!-- DataSource (HikariCP) -->
<dependency>
    <groupId>com.zaxxer</groupId>
    <artifactId>HikariCP</artifactId>
    <version>2.2.5</version>
</dependency>
<!-- JPA Provider (Hibernate) -->
<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-entitymanager</artifactId>
    <version>4.3.8.Final</version>
</dependency>
<!-- Spring Data JPA -->
<dependency>
    <groupId>org.springframework.data</groupId>
    <artifactId>spring-data-jpa</artifactId>
    <version>1.7.2.RELEASE</version>
</dependency>
