以下web.xml了Struts2的過濾器映射

<web-app id="MyStrutsApp" version="2.4" 
    xmlns="http://java.sun.com/xml/ns/j2ee" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"> 

    <filter> 
     <filter-name>struts2</filter-name> 
     <filter-class>org.apache.struts2.dispatcher.filter.StrutsPrepareAndExecuteFilter</filter-class> 
    </filter> 

    <filter-mapping> 
     <filter-name>struts2</filter-name> 
     <url-pattern>/*</url-pattern> 
    </filter-mapping> 

    <!-- ... --> 

</web-app>
