tomcat 禁止列出目录

      在Tomcat的conf/web.xml文件里把listings值改为false
如:

     < servlet >
         < servlet-name > default </ servlet-name >
         < servlet-class > org.apache.catalina.servlets.DefaultServlet </ servlet-class >
         < init-param >
             < param-name > debug </ param-name >
             < param-value > 0 </ param-value >
         </ init-param >
         < init-param >
             < param-name > listings </ param-name >
             < param-value > false </ param-value >
         </ init-param >
         < load-on-startup > 1 </ load-on-startup >
     </ servlet >
