java - 初始 SessionFactory 创建 failed.org.hibernate.AssertionFailure：不是加入的子类

Question

我使用了这篇文章： http: //viralpatel.net/blogs/2011/12/hibernate-inheritance-table-per-subclass-annotation-xml-mapping.html用于每个子类 hbm 方法的 Hibernate 继承表。当我运行主类时，我得到以下异常。

12/02/16 00:02:24 ERROR hibernate.AssertionFailure: an assertion failure occured (this may indicate a bug in Hibernate, but is more likely due to unsafe use of the session)

有任何想法吗 ？
