tomcat 6 利用ExpiresFilter控制静态文件缓存

在tomcat7下面 利用ExpiresFilter来控制静态文件缓存很方便，按照tomcat官网手动配置即可：

但是tomcat6 里面并没有

org.apache.catalina.filters.ExpiresFilter

这个接口类。

解决办法如下：引入  ExpiresFilter-1.0.0.jar
下载jar：
http://files.cnblogs.com/files/qiaoyihang/ExpiresFilter-1.0.0.zip
下载源码：

https://github.com/bnegrao/ExpiresFilter

然后更改配置如下：

<filter>

 <filter-name>ExpiresFilter</filter-name>

 <filter-class>bnegrao.filters.ExpiresFilter</filter-class>

 <init-param>

    <param-name>ExpiresByType image</param-name>

    <param-value>access plus 10 minutes</param-value>

 </init-param>

 <init-param>

    <param-name>ExpiresByType text/css</param-name>

    <param-value>access plus 10 minutes</param-value>

 </init-param>

 <init-param>

    <param-name>ExpiresByType application/javascript</param-name>

    <param-value>access plus 10 minutes</param-value>

 </init-param>

</filter>

...

<filter-mapping>

 <filter-name>ExpiresFilter</filter-name>

 <url-pattern>/*</url-pattern>

 <dispatcher>REQUEST</dispatcher>

</filter-mapping>
