filter 指定多个Url-pattern

通过指定多个<filter-mapping>可以指定多个url-pattern,下面是个例子:

<filter>
  <filter-name>encodingFilter</filter-name>
  <filter-class>com.cs.cms.filter.EncodingFilter</filter-class>
  <init-param>
   <param-name>encoding</param-name>
   <param-value>gbk</param-value>
  </init-param>
 </filter>
 <filter-mapping>
  <filter-name>encodingFilter</filter-name>
  <url-pattern>*.html</url-pattern>
 </filter-mapping>

<filter-mapping>
  <filter-name>encodingFilter</filter-name>
  <url-pattern>*.jsp</url-pattern>
 </filter-mapping>
