一、该问题的重现步骤是什么？

1. 目前有两种用户，后台管理用户和会员用户，分别在不同的表，想要实现鉴权后返回不同的信息

2. 改造类UserInfo，如下：

新增后台用户类BackUserInfo和会员用户类MemberUser

在BladeUserDetailsServiceImpl 类修改，根据userType走不同的逻辑获取用户信息，

其中，获取用户信息的方法为：

3.通过saber页面登录报错，报错信息为

调用查询用户信息的方法，返回信息为;

在BladeUserDetailsServiceImpl 中打断点看到的信息为：

二、你期待的结果是什么？实际看到的又是什么？

期待：类型正常转换

实际：UserInfo 类里确实user类信息，导致转换异常

三、你正在使用的是什么产品，什么版本？在什么操作系统上？

bladex2.5、win10

四、请提供详细的错误堆栈信息，这很重要。
