filter- Configure multiple filter URLs

1. The completely wrong way

<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>  

2. It has a certain effect, but it cannot achieve the desired effect. It will only filter the url-pattern configured at the bottom

<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>  

Three, now give the correct configuration method

<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>
