maven tomcat:run指定tomcat7:

配置好下面的内容后，执行 run as -> tomcat7:run 或者tomcat6:run可以将maven的web应用在tomcat6/7里面运行 ,eclipse Indigo 版本默认tomcat:run是用tomcat6。

 DelegatingFilterProxy cannot be cast to Filter

 过程中遇到了一个情况，就是打成war包放到webapps下面运行时正常 的，但是用tomcat:run会报错：org.springframework.web.filter.DelegatingFilterProxy cannot be cast to javax.servlet.Filter；

检查一下：

pom.xml文件编辑器（一般要装插件才能看到）下面的dependency hierarchy 里面，在右边框图里面找到servlet-api.jar，选中后在左边，右键->exclude maven artifact，去除依赖关系。
