How to redirect URLs with trailing slash to the corresponding ones without it?

Spring MVC (3.0) considers URLs with and without trailing slashes as the same URL.

For example:

http://www.example.org/data/something = http://www.example.org/data/something/

I need to redirect the URL with trailing slashes

http://www.example.org/data/something/

to the URL without it:

http://www.example.org/data/something

I need to do this internally the application (so not rewrite rules via Apache, etc).

A way to do it is:

@ResponseStatus(value=HttpStatus.MOVED_PERMANENTLY)
@RequestMapping(value = "/data/something/")
public String dataSomethingRedirect(...) {
    return "redirect:/data/something";
}

but this has generally 2 problems:

1. too many controllers
2. problem with parameters: like wrong encoding

Question

Is there a way to intercept all the URLs and in case they have a trailing slash, redirect them to the relative one without slash?
