web.xml里配置下载文件

web.xml里配置下载文件

我们有时需要从服务器端下载一个文件，比如POI中我写的Excel文件，它是直接使用浏览器打开的，但是我们要下载到本地，其实在web.xml里配置下就OK了：

 

< mime-mapping >  
< extension > doc </ extension >
< mime-type > application/msword </ mime-type >  
</ mime-mapping >  
< mime-mapping >  
< extension > xls </ extension >  
< mime-type > application/msexcel </ mime-type >  
</ mime-mapping >  
< mime-mapping >  
< extension > pdf </ extension >  
< mime-type > application/pdf </ mime-type >  
</ mime-mapping >
< mime-mapping >  
< extension > zip </ extension >  
< mime-type > application/zip </ mime-type >  
</ mime-mapping >
< mime-mapping >  
< extension > rar </ extension >  
< mime-type > application/rar </ mime-type >  
</ mime-mapping >
< mime-mapping >  
< extension > txt </ extension >  
< mime-type > application/txt </ mime-type >  
</ mime-mapping >
< mime-mapping >  
< extension > chm </ extension >  
< mime-type > application/mshelp </ mime-type >
</ mime-mapping >  
< mime-mapping >
  < extension > mp3 </ extension >
  < mime-type > audio/x-mpeg </ mime-type >
</ mime-mapping >
