Tomcat 下载rar文件直接以乱码方式打开解决方案

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"
-->
