web.xml里filter的一些配置

引用

<filter>
   <filter-name>charsetFilter</filter-name>
   <filter-class>filter.CharsetFilter</filter-class>
</filter>
<filter-mapping>
    <filter-name>charsetFilter</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

这个就不用解释了。
看下面这个。。。

<filter>
     <filter-name>Privilege filter</filter-name>
     <filter-class>filter.PrivilegeFilter</filter-class>
     <init-param>
<param-name>failpage1</param-name>
         <param-value>error.jsp</param-value>
     </init-param>
     <init-param>
         <param-name>failpage2</param-name>
<param-value>error.jsp</param-value>
     </init-param>
</filter>
<filter-mapping>
     <filter-name>Privilege filter</filter-name>
     <servlet-name>action</servlet-name>
</filter-mapping>

这个是对所有action(struts里的action)进行过滤
