使用hibernate的时候，配置主配置文件(hibernate.cfg.xml)时，遇到了这个异常

异常信息（根本原因）：

<session-factory name="sessionfactory">  ... ..  </session-factory>这个元素间，你写的一些配置信息，必须要遵循这样的顺序，从头到尾写！

1.<property></property>(节点写在最前面)

2.<mapping></mapping>(把mapping节点写到了某个property前面，出现上述异常)

3.(class-cache|collection-cache)

 4.<event></event>

5.<listener></listener>
