Answer 3

<filter>
<filter-name>a </filter-name>
<filter-class>com.FileterClass </filter-class>
</filter>
<filter-mapping>
<filter-name>a </filter-name>
<url-pattern>*.jsp </url-pattern>
</filter-mapping>
<filter-mapping>
<filter-name>a </filter-name>
<url-pattern>*.do </url-pattern>
</filter-mapping>一个filter可以配置多个filter-mapping。这点上web.xml非常不智能，来一起骂sun吧、
