web.xml文件中配置<mime-mapping>下载文件类型
TOMCAT在默认情况下下载.rar的文件是把文件当作text打开,以至于IE打开RAR文件为乱码,如果遇到这种情况时不必认为是浏览器的问题,大多数浏览器应该不会死皮赖脸地把二进制文件当作文本打开,一般都是服务器给什么浏览器就开什么.解决方法:
打开conf/web.xml,加入下面的代码.
<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>
重启TOMCAT,清除IE缓存,再打开RAR的文件时就可以正常下载了.
不同的ContentType 会影响客户端所看到的效果.
默认的ContentType为 text/html 也就是网页格式.
代码如:
<% response.ContentType ="text/html" %>
<!--＃i nclude virtual="/ContentType.html" -->
显示的为网页,而
<% response.ContentType ="text/plain" %>
<!--＃i nclude virtual="/sscript/ContentType.html" -->
则会显示html原代码.
以下为一些常用的 ContentType
GIF images
<% response.ContentType ="image/gif" %>
<!--＃i nclude virtual="/myimage.gif" -->
JPEG images
<% response.ContentType ="image/jpeg" %>
<!--＃i nclude virtual="/myimage.jpeg" -->
TIFF images
<% response.ContentType ="image/tiff" %>
<!--＃i nclude virtual="/myimage.tiff" -->
MICROSOFT WORD document
<% response.ContentType ="application/msword" %>
<!--＃i nclude virtual="/myfile.doc" -->
RTF document
<% response.ContentType ="application/rtf" %>
<!--＃i nclude virtual="/myfile.rtf" -->
MICROSOFT EXCEL document
<% response.ContentType ="application/x-excel" %>
<!--＃i nclude virtual="/myfile.xls" -->
MICROSOFT POWERPOINT document
<% response.ContentType ="application/ms-powerpoint" %>
<!--＃i nclude virtual="/myfile.pff" -->
PDF document
<% response.ContentType ="application/pdf" %>
<!--＃i nclude virtual="/myfile.pdf" -->
ZIP document
<% response.ContentType ="application/zip" %>
<!--＃i nclude virtual="/myfile.zip" -->
