如果你采用了annotation的方式来注入，就没有必要在xml里面配置一次了
你直接删掉annotation试试。看配置文件没什么问题
除非你 pro.login.service.UserServiceImpl userService
解决办法：
1.删掉annotation
2.把 loginController里面的UserService属性改为小写的userService
3.给loginController的userService 一个setter方法
4. <property name="UserService" ref="UserService" />
改成 <property name="userService" ref="UserService" />
