Tomcat 在IE中下载rar文件为乱码解决方案

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
