Grails: URL mapping - how to pass file extension?

问题:

I have some folder with different files. I want to use something like this: http://myserver.com/foo/bar/test.html

I'm using this way to obtain path:

"/excursion/$path**" (controller:"excursion", action:"sweet")  

But it doesn't helps with file extensions... How to disable file extensions truncating ?

P.S.

class ExcursionController {
 def defaultAction = "sweet"

 def sweet = {
  render "${params.path}"
 }
}

Request http://myserver.com/excursion/foo/bar/test.html

The result is "foo/bar/test" with no extension :(

回答1:

what does

render "${params.path}.${request.format}"

give you?

回答2:

Disable file extension truncation by adding this line to grails-app/conf/Config.groovy:

grails.mime.file.extensions = false

This impacts content negotiation, so I suggest you read section 7.8 of the Grails user guide
