maven中hibernate-core和struts2-core中javassist解决办法(cannot be cast to javassist.util.proxy.Proxy)

今天写基于maven的ssh项目的时候出现

主要上网搜了：cn.lichenyang.dms.entity.BcStaff_$$_javassist_11 cannot be cast to javassist.util.proxy.Proxy

网上说的是struts2-core和hibernate-core中的2个javassist的包有冲突，具体的结解决办法是：
我是写定时发送邮件的时候出现这个问题的，我的功能方法写在action包的下面的，所以打开action中的pom文件
点击如图位置，会发现有2个版本的javassist包名



单击低版本的(一般都是struts2的版本低)会出现如下界面，右键点击会出现如下界面





点击鼠标所在位置之后，eclipse会自动在pom文件中不调用点击的那个包，更新maven再次运行就行了
大家也可以去Maven中jar版本冲突问题的解决查看
