Question

我正在让Hibernate与OSGi一起工作，所以这个项目的基础是org.hibernate.osgi。

我已经创建了 persistence.xml ，并尝试使用以下代码访问它：

BundleContext context = FrameworkUtil.getBundle(getClass()).getBundleContext();
ServiceReference serviceReference = context.getServiceReference(PersistenceProvider.class.getName());
PersistenceProvider persistenceProvider = (PersistenceProvider) context.getService(serviceReference);
EntityManagerFactory emf = persistenceProvider.createEntityManagerFactory("DemoUnit", null);

出于某种原因，在创建EntityManagerFactory时，会出现以下异常：

javax.xml.stream.FactoryConfigurationError: Provider com.bea.xml.stream.EventFactory not found
at javax.xml.stream.FactoryFinder.newInstance(FactoryFinder.java:72)
at javax.xml.stream.FactoryFinder.find(FactoryFinder.java:178)

at org.hibernate.osgi.OsgiPersistenceProvider.createEntityManagerFactory(OsgiPersistenceProvider.java:77)
at org.acme.project.MyTest.getFactory(MyTest.java:28)

我认为这是一个错误，因为我在任何P2存储库和Maven中心都找不到包com.bea.xml.stream。

但是如何让Hibernate接受任何其他XML提供程序？

（或者com.bea.xml.stream可能是什么。至少代码试图将这个'EventFactory'强制转换为'XMLEventFactory'。）

没有人能找到任何东西。打破Hibernate的包是com.springsource.javax.xml.stream。我用javax.xml.stream替换它，现在它可以工作。

Hibernate：找不到提供者com.bea.xml.stream.EventFactory
