无法加载JDBC驱动程序类＆＃39; com.mysql.jdbc.GoogleDriver＆＃39; - GAE + Java + Hibernate + Spring

Question

我正在尝试使用Push-to-deploy with CI（构建，测试，部署）为GAE设置项目，并且无法让我的测试运行。在我当地的电脑上一切都很好。

来自谷歌日志文件：

  integrationTest(my.package.theTest): Cannot load JDBC driver class 'com.mysql.jdbc.GoogleDriver'
  integrationTest(my.package.theTest): Could not open Hibernate Session for transaction; nested exception is org.hibernate.exception.GenericJDBCException: Could not open connection

我在GAE 上运行项目的配置是：

应用服务引擎-web.xml中

<appengine-web-app xmlns="http://appengine.google.com/ns/1.0">
    <application>my-app-id</application>
    <version>${appengine.app.version}</version>
    <threadsafe>true</threadsafe>
    <use-google-connector-j>true</use-google-connector-j>
</appengine-web-app>

dataSource.properties

jdbc.driverClassName=com.mysql.jdbc.GoogleDriver
jdbc.url=jdbc:google:mysql://my-app-id:my-instance/my_table?user=user
jdbc.username=user
jdbc.password=user

dataSource.xml

<bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
    <property name="location">
        <value>classpath:db/dataSource.properties</value>
    </property>
</bean>

<bean id="dataSource"
      class="org.apache.commons.dbcp.BasicDataSource">
    <property name="driverClassName" value="${jdbc.driverClassName}"/>
    <property name="url" value="${jdbc.url}"/>
    <property name="username" value="${jdbc.username}"/>
    <property name="password" value="${jdbc.password}"/>
</bean>

hibernate.xml

<import resource="dataSource.xml" />

<bean id="sessionFactory"
    class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
    <property name="dataSource" ref="dataSource" />
    <property name="packagesToScan" value="my.package" />
    <property name="hibernateProperties">
        <props>
            <prop key="hibernate.dialect">org.hibernate.dialect.MySQL5Dialect</prop>
            <prop key="hibernate.show_sql">false</prop>
        </props>
    </property>
    <property name="entityInterceptor" ref="modelInterceptor" />
</bean>

<bean id="transactionManager"
    class="org.springframework.orm.hibernate4.HibernateTransactionManager">
    <property name="sessionFactory" ref="sessionFactory" />
</bean>

<tx:annotation-driven transaction-manager="transactionManager" />

的applicationContext.xml

<import resource="db/hibernate.xml" />

AbstractDao.java

@Transactional
@Component
public class AbstractDao<T> implements Dao<T> {

    @Autowired
    SessionFactory sessionFactory;

    @Override
    public void save(T entity) {
        getSession().save(entity);
    }

// other dao code

    private Session getSession() {
        return sessionFactory.getCurrentSession();
    }

}
