tomcat配置虚拟目录后出现404的解决方法

在tomcat的conf / web.xml中，修改

<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><span style="color:#ff0000;">false</span></param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>

修改为:

<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><span style="color:#ff0000;background-color: rgb(255, 255, 255);">true</span></param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>
