Hibernate 在karaf和MS sql不工作的情况下休眠

我正在将Hibernate 5与MSSQL 2012连接。我能够使用java（main方法）成功地获得连接。但是当我部署在Karaf中时，它给了我错误：

Caused by: org.hibernate.boot.registry.classloading.spi.ClassLoadingException: Unable to load class [net.sourceforge.jtds.jdbc.Driver]

这是我的hibernate.cfg文件：

<hibernate-configuration>
  <session-factory>
    <property name="hibernate.connection.driver_class">net.sourceforge.jtds.jdbc.Driver</property>
    <property name="hibernate.connection.url">jdbc:jtds:sqlserver://<ip>:<port>/<dbname></property>
    <property name="hibernate.connection.username">testuser</property>
    <property name="hibernate.connection.password">abc</property>

    <property name="hibernate.dialect">org.hibernate.dialect.SQLServerDialect</property>


  </session-factory>
</hibernate-configuration>

---

但仍然存在错误。存储库也包含类（

Driver.class

），但我仍然收到此错误。有人能帮我解决这个问题吗？？我缺少什么？

通常在OSGi中，使用Driver.class加载jdbc驱动程序不起作用。 相反，您应该使用提供一个数据源作为OSGi服务，并使用Aries JPA使hibernate完全支持OSGi

我还没有使用MS-SQL，但pax jdbc也支持它。因此，它通常应该是有效的
