Answer 1

从hibernate 3迁移到hibernate 4时我遇到了同样的异常,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.

经典查询翻译器工厂的正确名称是org.hibernate.hql.classic.ClassicQueryTransactorFactory，在属性中使用它，而不是错误的 ( org.hibernate.hql.classic.ClassicQueryTransactionFactory)。
