Spring 3 how to handle multilanguage URL with same content

I want to fully internationalize my web page and have URLs translated to different languages. For example

• http://example.tld/en/page
• http://example.tld/de/pagina

all aforementioned pages should be handled by same controller and show same content (translated to desired language of course, this i know how to do - using message properties).

So my questions are:

1. How to achieve this functionality using @RequestMapping annotation?
2. Can I configure such aliases in properties or XML file and then "inject" them into controller? i.e.:

properties file:

alias.page=page:pagina

Controller

@RequestMapping("${alias.page}")
...

Or something like this.

Thanks for answers.
