如何在Tomcat 6中为任何文件扩展名设置默认的mime-tipe?

问题描述

MIME类型在Tomcat的conf/web.xml文件中指定.看起来像这样:

Mime-types are specified in Tomcat's conf/web.xml file.It's look like this:

<mime-mapping>
   <extension>txt</extension>
   <mime-type>text/plain</mime-type>
</mime-mapping>

以前，我尝试以下操作:

Previously I try following:

<mime-mapping>
   <extension>*</extension>
   <mime-type>application/octet-stream</mime-type>
</mime-mapping> 

但这对我没有帮助.如何为任何文件扩展名指定默认的mime类型?

but it doesn't help me.How to specify default mime-type for any file extension?

推荐答案

没有办法.您需要自己明确设置它们. servlet过滤器是适合此的地方.

There's no way. You need to explicitly set them yourself. A servlet filter is a suitable place for this.

public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws ServletException, IOException {
    response.setContentType("application/octet-stream");
    chain.doFilter(request, response);
}

但是，我高度质疑企业对此的需求.这对于SEO和客户来说都是不利的.如果您的唯一目的是弹出另存为对话框，那么您应该这样说.有比实现错误的mime类型更好的解决方案.

I however highly question the business need for this. It's only disadvantageous for SEO and the client. If your sole purpose is to pop a Save As dialogue, then you should say that so. There are much better solutions to achieve this than forcing a wrong mime type.
