该项目我使用idea编译访问没有任何问题，但使用eclipse编译时报错`No mapping found for HTTP request with URI [/sky-ssm/hello] in DispatcherServlet with name 'dispatcherServlet'`首先我检查了  
1、web.xml文件中的配置

都没有错误了但是不行，右键项目build path configure……选择libraries删除以前默认的tomcat更换tomcat之后就解决了

完成之后右键项目，maven update project 或者点击项目ALT+F5 更新一下maven再重新启动项目即可
