在java的WEB项目如何防止浏览器直接打开下载的文件



java的web项目防止浏览器直接打开下载的文件，在web.xml文件中配置mime下载文件类型就可以了，配置的示例：

<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>

这样就可以防止web程序在浏览器是直接打开文件，而是弹出下载框供用户下载了。
