在IE中通过a标签直接下载rar文件时以乱码方式打开

在JSP的下载文件中，如果文件是rar类型的，一点击下载rar文件就直接打开，并且出现乱码，右键另存为浏览器也是默认为html格式，一直以为是浏览器IE的问题，后来发现其实不关浏览器的问题，而是web.xml配置的问题，具体如下：

web.xml文件中配置下载文件类型

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,如果遇到这种情况解决方法:

打开conf/web.xml,加入下面的代码.

 doc

 application/msword

 xls

 application/msexcel

 pdf

 application/pdf

 zip

 application/zip

 rar

 application/rar

 txt

 application/txt

 chm

 application/mshelp

 mp3

 audio/x-mpeg

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juapk.com网页格式.

代码如:

显示的为网页,而

则会显示html原代码.

以下为一些常用的 ContentType

GIF images

 JPEG images

 TIFF images
