TOMCAT在默認情況下下載.rar的文件是把文件當作text打開,以至於IE打開RAR文件為亂碼,如果遇到這種情況時不必認為是瀏覽器的問題,大多數瀏覽器應該不會死皮賴臉地把二進制文件當作文本打開,一般都是服務器給什么瀏覽器就開什么.解決方法:
打開conf/web.xml,加入下面的代碼.
<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>
重啟TOMCAT,清除IE緩存,再打開RAR的文件時就可以正常下載了.
