解决INFO: HHH000206: hibernate.properties not found问题

入门Hibernate 时出现了：

Caused by: org.xml.sax.SAXParseException; cvc-complex-type.2.4.a: 发现了以元素 'property' 开头的无效内容。应以 '{"http://www.hibernate.org/xsd/orm/cfg":mapping, "http://www.hibernate.org/xsd/orm/cfg":class-cache, "http://www.hibernate.org/xsd/orm/cfg":collection-cache, "http://www.hibernate.org/xsd/orm/cfg":event, "http://www.hibernate.org/xsd/orm/cfg":listener}' 之一开头。

这是因为我在 hibernate.cfg.xml 中将 <property> 标签放到了 <mapping> 标签的下面，导致mapping下面的property标签失效。

解决：将 mapping 标签移到下面即可。
