在线，怎样避免输入一个url后，把服务器上该url下的所有文件都列出来。

Question

web.xml<servlet>
        <servlet-name>xxx</servlet-name>
        <servlet-class>
          A.B.C.XXX
        </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>
还有一个办法就是加
welcome-files

Answer 1

Tomcat中禁止列目录下的文件
在%Tomcat%/conf/web.xml中，把listings参数设置成false即可，如下：    <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>

Answer 2

把
<welcom-files>
a.jsp
</welcom-files>
加入web.xml就可以了
