Tomcat 在IE中下载rar文件直接以乱码体式格式打开解决规划

这几天一向很纳闷，在Tomcat安排的网站中的下载文件中，若是文件是rar类型的，一点击下载rar文件就直接打开，并且呈现乱码，右键另存为浏览器也是默认为html格局，一向认为是浏览器IE的题目，后来发明其实不关浏览器的题目，而是Tomcat办事器设备的题目，具体如下：

web.xml文件中设备<mime-mapping>下载文件类型
TOMCAT在默认景象下下载.rar的文件是把文件算作text打开，以至于IE打开RAR文件为乱码，若是碰到这种景象时不必认为是浏览器的题目，大多半浏览器应当不会逝世皮赖脸地把二进制文件算作文本打开，一般都是办事器给什么浏览器就开什么.解决办法:

 打开conf/web.xml，参加下面的代码.

 <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.

 不合的ContentType 会影响客户端所看到的结果.

 默认的ContentType为 text/html  也就是网页格局.

 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" -->
