报了这个莫名其妙的东西
------解决方案--------------------------------------------------------
可能原因：看看这个包 javassist.jar
如果没有问题的话，建议用以下方式调试下看看
<value>com/yanbai/entity/Ybdeviceapplyform.hbm.xml</value>
<value>com/yanbai/entity/Ybdeviceapplyformflow.hbm.xml</value>
<value>com/yanbai/entity/Ybdeviceapplyformitem.hbm.xml</value>
<value>com/yanbai/entity/Ybdeviceicon.hbm.xml</value>
<value>com/yanbai/entity/Ybdeviceitem.hbm.xml</value>
<value>com/yanbai/entity/Ybdeviceitemflow.hbm.xml</value>
<value>com/yanbai/entity/Ybdeviceitemstatus.hbm.xml</value>
<value>com/yanbai/entity/Ybdevicetree.hbm.xml</value>
这么多影射文件，一个一个加进来，不要一起加进来。
看看是加到哪个出的问题，去检查pojo类和hbm文件
如果解决不了，那么把exception的cause by部分贴来看看
