我正在使用Spring Data JPA和Hibernate处理应用程序,我正在尝试使用ehcache启用二级缓存.我将我的应用程序分解为两个项目:

• CoreDataFacade:我使用QueryDSL定义数据访问操作,Spring Data JPA使用Hibernate和ehcache.
• QueryComponent:是一个Spring引导项目,它使用CoreDataFacade项目来访问数据.

CoreDataFacade的配置如下:

的pom.xml

<dependencies>
    <dependency>
        <groupId>org.springframework.data</groupId>
        <artifactId>spring-data-jpa</artifactId>
        <version>1.7.3.RELEASE</version>
    </dependency>

    <dependency>
        <groupId>org.hibernate</groupId>
        <artifactId>hibernate-core</artifactId>
        <version>4.3.6.Final</version>
    </dependency>

    <dependency>
        <groupId>net.sf.ehcache</groupId>
        <artifactId>ehcache-core</artifactId>
        <version>2.4.7</version>
    </dependency>

    <dependency>
        <groupId>org.hibernate</groupId>
        <artifactId>hibernate-ehcache</artifactId>
        <version>4.3.6.Final</version>  
    </dependency>

    <dependency>
        <groupId>org.hibernate</groupId>
        <artifactId>hibernate-entitymanager</artifactId>
        <version>4.3.6.Final</version>
    </dependency>

    <dependency>
        <groupId>mysql</groupId>
        <artifactId>mysql-connector-java</artifactId>
        <version>5.1.33</version>
    </dependency>

    <dependency>

        <artifactId>querydsl-jpa</artifactId>
        <version>3.6.0</version>
    </dependency>

应用程序的context.xml

<jpa:repositories
    base-package="com.coredata.services.impl.sql.mysql.repositories" />
