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
<!DOCTYPE web-app PUBLIC

"http://java.sun.com/dtd/web-app_2_3.dtd" >

</listener>

<!--解决中午乱码过滤器-->

</init-param>
</filter>
<filter-mapping>
<filter-name>characterEncodingFilter</filter-name>

</filter-mapping>
</web-app>

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
