<code class="java">public ModelAndView someRequestHandler(@AuthenticationPrincipal User activeUser) { ... }</code>

<code class="java">public class CurrentUserWebArgumentResolver implements WebArgumentResolver {
    @Override
    public Object resolveArgument(MethodParameter methodParameter, NativeWebRequest webRequest) {
        if (methodParameter.isParameterType(User.class) && methodParameter.hasParameterAnnotation(ActiveUser.class)) {
            Principal principal = webRequest.getUserPrincipal();
            return (User) ((Authentication) principal).getPrincipal();
        } else {
            return WebArgumentResolver.UNRESOLVED;
        }
    }
}</code>

<code class="java">public class CurrentUserHandlerMethodArgumentResolver implements HandlerMethodArgumentResolver {
    @Override
