关于类存在，却报classnotfound

本来spring版本是3.2.8，现在升级成了4.3.3
于是在tomcat启动的时候，出现了下面的错误
org.springframework.beans.factory.CannotLoadBeanClassException: Cannot find class [com.dt5000.score.action.QuartzJobAction] for bean with name 'quartzJobAction' defined in class path resource [applicationContext-Basic.xml]; nested exception is java.lang.ClassNotFoundException: com.dt5000.score.action.QuartzJobAction

楼主 贴一张你的basic.xml 看一下，我最近也在学spring框架
