spring错误处理 Build path is incomplete. Cannot find class file for org.springframework.aop.Advisor

Build path is incomplete. Cannot find class file for org.springframework.aop.Advisor

初学spring，记录一下出现的错误

在写AOP的时候，出现了错误Build path is incomplete. Cannot find class file for org.springframework.aop.Advisor

解决办法：下载org.springframework.aop的jar文件

然后将zip文件解压，加入到path里面

错误解决。
