Filter 配置多个URL-PATTERN

文章出自：http://weidongke123-126-com.iteye.com/blog/1032546

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

<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>

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

<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、现在给出正确的配置方式

Java代码

<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>
