Why don't you show the update form after the binding fails, so the user can try to resubmit the form?

The standard approach for this seems to be to return the update form view from the POST handler method.

if (bindingResult.hasErrors()) {
  uiModel.addAttribute("user", user);
  return "user/create";
}

You can then display errors with the form:errors tag.
