tomcat7 中的坑。 关于welcome-list和servlet-mapping

web.xml中, 使用default servlet设置了针对静态资源后缀名的过滤. 并且设置了welcome-list, 使用jetty和tomcat6启动一切正常, 但是使用tomcat7则出现访问不到根节点(/)的情况. 

后来将红色部分去掉后才正常. 

 

原理和更优雅的解决方案:

Tomcat 6.0.30之前的security问题: https://issues.apache.org/bugzilla/show_bug.cgi?id=50026

使用spring的resource标签: http://docs.spring.io/spring/docs/3.0.5.RELEASE/spring-framework-reference/html/mvc.html#mvc-static-resources

不推荐使用容器自身的default servlet进行mapping: http://webmasters.stackexchange.com/questions/29550/why-the-difference-between-tomcat-and-tomcat7-regarding-servlet-mapping-and-defa 

关于静态资源mapping的问题: http://stackoverflow.com/questions/870150/how-to-access-static-resources-when-using-default-servlet/3593513#3593513
