spring mvc - Java Request Mapping URL wild card not matching special characters such as percenntage

Question

I'm trying to catch curl requests of https://somehosts.com/api/random, and give those response 200 code with a redirected page. (to avoid DoS).

In my API controller, I have a method at the end,

    @RequestMapping(value = "/**", method = RequestMethod.GET)
    @ResponseBody
    public void handleInvalidAPIReq() {
        return redirect();
    }

This is catching scenarios such as curl requests of https://somehosts.com/api/random-bad1234, but not for URLs with special characters such as %. how can I adjust the value of /** to catch invalid requests such as https://somehosts.com/api/%fhdjlsb%fhld please?

Thank you.

-----------------Update------------- Thanks for the reply. The ultimate goal is to catch scenarios such as https://somehosts.com/api/%uff0e%uff0e%u2216%7bFILE%7d, and seems we need to handle both reserved characters (e.g %,$,- etc) and decode to unicode and catch in the value. %uff0e%uff0e%u2216%7bFILE%7d looks need decoding.
