如果只配置攔截類似于*.do格式的url，則對靜態資源的訪問是沒有問題的，但是如果配置攔截了所有的請求（如我們上面配置的“/”），就會造成js文件、CSS文件、圖片文件等靜態資源無法訪問

一般Web應用服務器默認的Servlet名稱是"default"，所以這里我們激活Tomcat的defaultServlet來處理靜態文件

 Tomcat, Jetty, JBoss, and GlassFish  默認 Servlet的名字 -- "default"         Resin 默認 Servlet的名字 -- "resin-file"         WebLogic 默認 Servlet的名字  -- "FileServlet"         WebSphere  默認 Servlet的名字 -- "SimpleFileServlet"                 如果你所有的Web應用服務器的默認Servlet名稱不是"default"，則需要通過default-servlet-name屬性顯示指定
