SpringMVC拦截器筛选

如果只配置拦截类似于*.do格式的url，则对静态资源的访问是没有问题的，但是如果配置拦截了所有的请求（如我们上面配置的“/”），就会造成js文件、CSS文件、图片文件等静态资源无法访问

一般Web应用服务器默认的Servlet名称是"default"，所以这里我们激活Tomcat的defaultServlet来处理静态文件

 Tomcat, Jetty, JBoss, and GlassFish  默认 Servlet的名字 -- "default"         Resin 默认 Servlet的名字 -- "resin-file"         WebLogic 默认 Servlet的名字  -- "FileServlet"         WebSphere  默认 Servlet的名字 -- "SimpleFileServlet"                 如果你所有的Web应用服务器的默认Servlet名称不是"default"，则需要通过default-servlet-name属性显示指定
