javassist兩個jar包導致：.Department_$$_javassist_1 cannot be cast to javassist.util.proxy.Proxy

當處理如下代碼：

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>

當輸出數據到頁面時候出現如下錯誤：  

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

原因是有兩個javassis的jar包，一個是hibernate的，一個是struts2的...，把低版本的刪掉即可！
