Tomcat是直接显示目录结构和文件列表，只是在配置里面给关闭了。
关键在这里：\conf\web.xml
这个文件有一段配置直接控制Tomcat是允许显示目录结构和文件列表。
Java代码
<servlet>
default</servlet-name>
class>org.apache.catalina.servlets.DefaultServlet</servlet-class>
<init-param>
<param-name>debug</param-name>
0</param-value>
</init-param>
<init-param>
<param-name>listings</param-name>
false</param-value>
</init-param>
1</load-on-startup>
</servlet>把listings选项改为true就可以了。 另外把<welcome-file>的配置去掉
例子
org.apache.catalina.servlets.DefaultServlet支持许多配置选项，在这个web.xml文件里面都有注释。 Java代码
