request mapping with special char for attributes similar to google maps

I am using Spring boot and I want to pass two double values in a manner similar to Google maps: instead of having /api?x=1.1&y=2.2 and get the request parameters I want to do: /api/@1.1,2.2

At the level of the controller, how can I get those two parameters from the second get request?

@GetMapping("/api/@{term:.+}")
public void index(@PathVariable String term) {
    // term is whatever after the "@"
    // you can parse the term to what you want
    // {term:.+} is a regex mapping for including the last dot
}

e.g.
If you request ../api/@1.1,2.2
Term will be "1.1,2.2".
Split the term by "," and convert the strings to doubles.
