service 层报错日志

java.lang.NullPointerException
	com.yjm.service.UserInfoService.verifyUserLoginInfo(UserInfoService.java:21)
	com.yjm.service.UserInfoService$$FastClassByCGLIB$$635690a4.invoke(<generated>)
	net.sf.cglib.proxy.MethodProxy.invoke(MethodProxy.java:191)

可见是代理对象在处理业务，而不是spring 注入的bean再处理业务。
