从hibernate 3迁移到hibernate 4时我有同样的异常,但是当我试图改变它时

<property name="hibernate.query.factory_class">org.hibernate.hql.classic.ClassicQueryTranslatorFactory</property>

同

<property name="hibernate.query.factory_class">org.hibernate.hql.internal.classic.ClassicQueryTranslatorFactory</property>

它对我有用.

我希望能帮助你.
