struts2的filter问题

Question

<filter>
<filter-name>struts2</filter-name>
<filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>  
</filter>
<filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
该过滤器这样是过滤所有的请求URL，请问<servlet>
<servlet-name>UserService</servlet-name>
<servlet-class>com.sun.xml.ws.transport.http.servlet.WSServlet</servlet-class>
</servlet>

<servlet-mapping>
<servlet-name>UserService</servlet-name>
<url-pattern>/us</url-pattern>
</servlet-mapping>如果某个URL不想让struts2的filter过滤，要怎么做？谢谢了

Answer 1

<url-pattern>/*</url-pattern>
这个也只是默认拦截action后缀的请求，真正达到目的自定义一个filter吧

Answer 2

<filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>*.action</url-pattern>
</filter-mapping>
<filter-mapping>
    <filter-name>struts2</filter-name>
     <url-pattern>*.jsp</url-pattern>
</filter-mapping> 这样struts2过滤器就只过滤action
struts2默认是不识别jsp的，因此要将jsp的文件映射到struts2
