        <filter-name>struts2</filter-name>
        <filter-class>
            xxx.yyy.platform.base.filter.StrutsFilter
        </filter-class>
        <init-param>
            <param-name>patternPathConfig</param-name>
            <param-value>struts</param-value>
        </init-param>
    </filter>
 
    <filter-mapping>
        <filter-name>struts2</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>
