How to limit USER requests in ServletAPI (Spring MVC)

Question

How can I allow only one micorservice method request with a specific URL @PathVariableper user. My controller

@RestController
@RequestMapping(value = "/rest/product", produces = "application/json;charset=UTF-8")
public class ProductRestController {
    @Autowired
    ProductService productService;

    @Autowired
    ProductAsm productAsm;

    @RequestMapping(value = "/ID/{ID}", method = RequestMethod.GET)
    public ResponseEntity<ProductResource> getProductID(@PathVariable("ID") Long ID, @AuthenticationPrincipal User) {

        Product product = productService.getProduct(ID);
        if (product == null)
            return new ResponseEntity<>(HttpStatus.NOT_FOUND);

        return new ResponseEntity<>(productAsm.toResource(product), HttpStatus.OK);
    }

For example:

• first request /rest/product/ID/2231allowed for USER (with login = "xaxa")
• second request /rest/product/ID/2545allowed for USER (with login = "xaxa")
• Third request is /rest/product/ID/2231not allowed for USER (with login = "xaxa")

What is the best way to implement this functionality? (Should I store this request URL with the user login in the database or is there already a solution)
