javassist两个jar包导致：.Department_$$_javassist_1 cannot be cast to javassist.util.proxy.Proxy

当处理如下代码：

1 2	Javassist Enhancement failed: com.entities.Department java.lang.ClassCastException: com.entities.Department_$$_javassist_1 cannot be cast to javassist.util.proxy.Proxy

 

1 2 3

<many-to-one name= "department" class = "com.entities.Department" >             <column name= "DEPARTMENT_ID" />         </many-to-one>

当输出数据到页面时候出现如下错误：  

1 2	Javassist Enhancement failed: com.entities.Department java.lang.ClassCastException: com.entities.Department_$$_javassist_1 cannot be cast to javassist.util.proxy.Proxy

原因是有两个javassis的jar包，一个是hibernate的，一个是struts2的...，把低版本的删掉即可！
