get the request path in a spring controller

How can I get the matched request path in an HTTP mapping method in a spring application? In the following example, I want matchedPath variable to have the value /api/products/{product_id}/comments which is a combination of @RequestMapping and @PostMapping value.

@RestController
@RequestMapping("/api")
public class Example {

    @PostMapping("/products/{product_id}/comments")
    public ResponseEntity doSomething(@PathVariable("product_id") String id) {
        // String matchedPath = getPath();
        return ResponseEntity.ok().build();
    }

}

I found it is doable via one of HandlerMapping attributes BEST_MATCHING_PATTERN_ATTRIBUTE

import javax.servlet.http.HttpServletRequest;

@RestController
@RequestMapping("/api")
public class Example {

    @PostMapping("/products/{product_id}/comments")
    public ResponseEntity doSomething(HttpServletRequest req, @PathVariable("product_id") String id) {
        String matchedPath = String.valueOf(req.getAttribute(HandlerMapping.BEST_MATCHING_PATTERN_ATTRIBUTE));
        return ResponseEntity.ok().build();
    }

}
