web.xml文件中配置mime下载文件类型(转)

转自：http://5aijava.iteye.com/blog/166600

　　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>

重启TOMCAT,清除IE缓存,再打开RAR的文件时就可以正常下载了.

1.指定了自己的javaEncoding

(参考 http://gceclub.sun.com.cn/staticcontent/html/sunone/app7/app7-dg-webapp/ch6/ch6-4.html     <servlet>
        <servlet-name>jsp</servlet-name>
        <servlet-class>org.apache.jasper.servlet.JspServlet</servlet-class>
        <init-param>
            <param-name>fork</param-name>
            <param-value>false</param-value>
        </init-param>
                <init-param>
            <param-name>javaEncoding</param-name>
            <param-value>GB18030</param-value>
        </init-param>
        <init-param>
            <param-name>xpoweredBy</param-name>
            <param-value>true</param-value>
        </init-param>
        <load-on-startup></load-on-startup>
    </servlet>

2.添加rar,iso等的mime-type映射 
避免在浏览器里直接打开。

<mime-mapping>
<extension>mht</extension>
<mime-type>text/x-mht</mime-type>
</mime-mapping>
<mime-mapping>
        <extension>rar</extension>
        <mime-type>application/octet-stream</mime-type>
    </mime-mapping>
    <mime-mapping>
        <extension>iso</extension>
        <mime-type>application/octet-stream</mime-type>
    </mime-mapping>
    <mime-mapping>
        <extension>ape</extension>
        <mime-type>application/octet-stream</mime-type>
    </mime-mapping>
    <mime-mapping>
        <extension>rmvb</extension>
        <mime-type>application/octet-stream</mime-type>
    </mime-mapping>
    <mime-mapping>
        <extension>ico</extension>
        <mime-type>image/x-icon</mime-type>
    </mime-mapping> 

   <mime-mapping>
   <extension>doc</extension>
<mime-type>application/msword</mime-type>
</mime-mapping>
<mime-mapping>
   <extension>xls</extension>
   <mime-type>application/vnd.ms-excel</mime-type>
</mime-mapping>
<mime-mapping>
   <extension>ppt</extension>
   <mime-type>application/vnd.ms-powerpoint</mime-type>
</mime-mapping> 

3.对html静态页面设置编码

<!--  修改下面两行以支持静态超文本的自动编码
  -->
<mime-mapping>
  <extension>htm</extension>
  <mime-type>text/html;charset=gb2312</mime-type>
  </mime-mapping>
<mime-mapping>
  <extension>html</extension>
  <mime-type>text/html;charset=gb2312</mime-type>
  </mime-mapping>
  </web-app>
