What does @DeleteMapping do in Spring MVC?

@DeleteMapping maps HTTP DELETE requests to a handler method, used for removing a resource identified by a path variable — e.g. deleteUser(@PathVariable Long id). DELETE is expected to be idempotent: calling it multiple times on the same (now already-deleted) resource should still result in the resource being absent, typically returning a 204 No Content on success or a 404 if it was already gone.
