web应用程序的缺省servlet

web应用程序的缺省servlet

如果某个servlet的映射路径为“/”的时候，那么这个servlet就成为当前应用程序的缺省servlet
“<url-pattern>/</url-pattern>”

服务器上发送静态html文件和图片文件，基本上通过缺省servlet实现的

 

Tomcat的web.xml中：

    <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>

 

    <servlet-mapping>
        <servlet-name>default</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>
