我正在使用Spring Framework 3.1和Hibernate 4.1作为JPA提供程序,我有一个功能齐全的设置,但每次启动Web应用程序时,我都会看到以下警告消息:

14:28:12,725  WARN pool-2-thread-12 internal.EntityManagerFactoryRegistry:80 - HHH000436: Entity manager factory name (something) is already registered.  If entity manager will be clustered or passivated, specify a unique value for property 'hibernate.ejb.entitymanager_factory_name'

该应用程序功能很好,但是这样的警告信息让我烦恼,而且数小时的搜索,调整和试验都让我无处可去.我已经尝试更改工厂名称并添加和省略配置块,但都无济于事.似乎Spring或Hibernate中的某些东西只是初始化实体管理器工厂两次.

仅供参考,我正在使用LocalContainerEntityManagerFactoryBean的packagesToScan功能来配置没有persistence.xml文件的实体管理器.

我已经将我的spring上下文XML减少到以下内容并且问题仍然存在:
