Question

strust2中使用urlwrite后，strust2中ognl表达怎么用不了，获取不了值，请各位知道的兄弟姐妹们帮帮忙啊，给解答一下啊。
下面是web.xml配置：
<filter-mapping>
        <filter-name>action2-cleanup</filter-name>
        <url-pattern>/*</url-pattern>
        <dispatcher>REQUEST</dispatcher>   
<dispatcher>FORWARD</dispatcher>
    </filter-mapping>
    <filter-mapping>
        <filter-name>action2</filter-name>
        <url-pattern>/*</url-pattern>
        <dispatcher>REQUEST</dispatcher>   
<dispatcher>FORWARD</dispatcher>
<dispatcher>INCLUDE</dispatcher>
    </filter-mapping> <filter-mapping>   
        <filter-name>UrlRewriteFilter</filter-name>     
        <url-pattern>/*</url-pattern>
        <dispatcher>REQUEST</dispatcher>   
<dispatcher>FORWARD</dispatcher>       
    </filter-mapping>

Answer 1

 <filter-name>UrlRewriteFilter</filter-name>   UrlRewriteFilter在那里配置的呢？

Answer 2

也是在web。xml中配置的，不好意识，前面我只是截了部分代码，
下面是urlwrite玩转配置：
 <!-- UrlRewriteFilter filter-->      
    <filter>     
        <filter-name>UrlRewriteFilter</filter-name>     
        <filter-class>     
            org.tuckey.web.filters.urlrewrite.UrlRewriteFilter      
        </filter-class>     
        <init-param>     
            <param-name>logLevel</param-name>     
            <param-value>WARN</param-value> 
        </init-param> 
        <init-param>     
            <param-name>confPath</param-name>   
    <param-value>/WEB-INF/urlrewrite.xml</param-value>      
        </init-param>     
    </filter>     
    <filter-mapping>   
        <filter-name>UrlRewriteFilter</filter-name>     
        <url-pattern>/*</url-pattern>
        <dispatcher>REQUEST</dispatcher>   
<dispatcher>FORWARD</dispatcher>       
    </filter-mapping>
