Re: [Springframework-developer] Re: Plans for mime type in Resource?

[Andy D. <an...@ma...>]

Well, actually, here is what I was thinking.  Say that I pull a resource from 
a file or classpath (file: or classpath: or even just a relative path).  
Then, sure, just figure out the mime type based on file extension when I call 
"getMimeType" (or whatever) against the Resource.  That at least saves me the 
trouble of parsing the filename or calling into the activation framework.  
BUT, if I pass in a URL to a resource where the mime type is handled 
independently of the filename (such as a "http:" URL, where the server will 
return a type header), then return the specific mime type that was returned 
by the server.  See URL.openConnection().getContentType().  A simple 
algorithm could be:

getMimeType() {
  return URL.openConnection().getContentType() if not null,
  otherwise parse filename/use activation framework.
}
