WARN deprecation:&L - HHH90000012: Recognized obsolete hibernate namespace http://hibernate.sourceforge.net/hibernate-configuration. Use namespace http://www.hibernate.org/dtd/hibernate-configuration instead.  Support for obsolete DTD/XSD namespaces may be removed at any time.

其实这个警告，很容易解决，这段警告信息也很清楚，就是说我在hibernate.cfg.xml文件中使用的dtd名称空间http://hibernate.sourceforge.net/hibernate-configuration已经过时了

需要使用新的名称空间http://www.hibernate.org/dtd/hibernate-configuration

说明一下我使用的hibernate版本是5.2.8
