Spring Boot - REST Controllers

Examine the following Spring Boot controller method intended to delete an order by ID:

@DeleteMapping("/orders")
public void removeOrder(@PathVariable Long orderId) {
    // deletion logic
}

What is the issue with this method?

It should be @DeleteMapping("/orders/{orderId}") to match the @PathVariable parameter.
