直接用filter监听
public class MyFilter extends HttpServlet implements Filter
然后在web.xml中配置：
<filter>
<filter-name>myfilter</filter-name>
<filter-class>com.fiter.MyFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>myfilter</filter-name>
<url-pattern>*.jsp</url-pattern>
</filter-mapping>
<filter-mapping>
<filter-name>myfilter</filter-name>
<url-pattern>/servlet/*</url-pattern>
</filter-mapping>
