mime-mapping是web.xml中的一个节点，用来指定对应的格式的浏览器处理方式，常用的集中配置如下：
<mime-mapping> <extension>mht</extension> <mime-type>text/x-mht</mime-type> </mime-mapping> <mime-mapping> <extension>rar</extension> <mime-type>application/octet-stream</mime-type> </mime-mapping> <mime-mapping> <extension>iso</extension> <mime-type>application/octet-stream</mime-type> </mime-mapping> <mime-mapping> <extension>ape</extension> <mime-type>application/octet-stream</mime-type> </mime-mapping> <mime-mapping> <extension>rmvb</extension> <mime-type>application/octet-stream</mime-type> </mime-mapping> <mime-mapping> <extension>ico</extension> <mime-type>image/x-icon</mime-type> </mime-mapping> <mime-mapping> <extension>doc</extension> <mime-type>application/msword</mime-type> </mime-mapping> <mime-mapping> <extension>xls</extension> <mime-type>application/vnd.ms-excel</mime-type> </mime-mapping> <mime-mapping> <extension>ppt</extension> <mime-type>application/vnd.ms-powerpoint</mime-type> </mime-mapping>另外也可以用来配置静态页面的打开编码：
<!-- 修改下面两行以支持静态超文本的自动编码 --> <mime-mapping> <extension>htm</extension> <mime-type>text/html;charset=gb2312</mime-type> </mime-mapping> <mime-mapping> <extension>html</extension> <mime-type>text/html;charset=gb2312</mime-type> </mime-mapping>参考文档：
