一个Filter需要配置多个url-pattern

最近做项目遇到一个Filter需要配置多个url-pattern,上网查了下资料，经测试，现总结下

一、完全错误的方式

Java代码

1. <filter>
2. <filter-name>authority</filter-name>
3. <filter-class>com.util.AuthorityFilter</filter-class>
4. </filter>
5. <filter-mapping>
6. <filter-name>authority</filter-name>
7. <url-pattern>/pages/cmm/*;/pages/genbill/*</url-pattern>
8. </filter-mapping>

二、有一定作用，但不能实现需要的效果，只会过滤最下面配置的url-pattern。

Java代码 

1. <filter>
2. <filter-name>authority</filter-name>
3. <filter-class>com.util.AuthorityFilter</filter-class>
4. </filter>
5. <filter-mapping>
6. <filter-name>authority</filter-name>
7. <url-pattern>/pages/cmm/*</url-pattern>
8. <url-pattern>/pages/genbill/*</url-pattern>
9. </filter-mapping>

三、现在给出正确的配置方式

Java代码

1. <filter>
2. <filter-name>authority</filter-name>
3. <filter-class>com.util.AuthorityFilter</filter-class>
4. </filter>
5. <filter-mapping>
6. <filter-name>authority</filter-name>
7. <url-pattern>/pages/genbill/*</url-pattern>
8. </filter-mapping>
9. <filter-mapping>
10. <filter-name>authority</filter-name>
11. <url-pattern>/pages/cmm/*</url-pattern>
12. </filter-mapping>
