本文介绍了如何正确配置Web应用中的过滤器(filter)以实现特定URL路径的拦截与处理。包括了针对不同应用服务器如Tomcat和WebSphere的有效配置方法，并区分了正确与错误的配置方式。

一、正确的配置方法，配置多个filter-mapping

<filter>  
    <filter-name>authority</filter-name>  
    <filter-class>com.util.AuthorityFilter</filter-class>  
</filter>  
<filter-mapping>  
    <filter-name>authority</filter-name>  
    <url-pattern>/pages/genbill/*</url-pattern>  
</filter-mapping>  
<filter-mapping>  
    <filter-name>authority</filter-name>  
    <url-pattern>/pages/cmm/*</url-pattern>  
</filter-mapping>

二、tomcat下正确，websphere下只能处理最后一个url-pattern

<filter>  
    <filter-name>authority</filter-name>  
    <filter-class>com.util.AuthorityFilter</filter-class>  
</filter>  
<filter-mapping>  
    <filter-name>authority</filter-name>  
    <url-pattern>/pages/cmm/*</url-pattern>  
    <url-pattern>/pages/genbill/*</url-pattern>  
</filter-mapping>

三、错误的

<filter>  
    <filter-name>authority</filter-name>  
    <filter-class>com.util.AuthorityFilter</filter-class>  
</filter>  
<filter-mapping>  
    <filter-name>authority</filter-name>  
    <url-pattern>/pages/cmm/*;/pages/genbill/*</url-pattern>  
</filter-mapping>
