java.lang.ClassNotFoundException: org.springframework.web.util.IntrospectorCleanupListener

今天启动maven项目时，报了这个错:

 java.lang.ClassNotFoundException: org.springframework.web.util.IntrospectorCleanupListener

仔细看看配置，是没有问题，

解决办法:

①选中项目->右键Properties->选择Deployment Assemby->选择Add->选中Java Build Path Entries->Next->选择Maven Dependencies->Finish->Apply->OK

网上搜索，看到一篇总结的很好的博客
