如何从自定义webClient Builder获取webflux Webclient指标

WebClient.Builder customWebClientBuilder = WebClient.builder()
        .baseUrl("http://example.com")
        .defaultHeader(HttpHeaders.CONTENT_TYPE, MediaType.APPLICATION_JSON_VALUE)
        .defaultCookie("cookieName", "cookieValue")
        // 添加其他配置选项
        .clientConnector(new ReactorClientHttpConnector(HttpClient.newConnection().compress(true)));

public class CustomMetricsFilter implements ExchangeFilterFunction {
    private Timer.Sample sample;

    @Override
    public Mono<ClientResponse> filter(ClientRequest request, ExchangeFunction next) {
        sample = Timer.start();
        return next.exchange(request)
                .doOnTerminate(() -> {
                    if (sample != null) {
                        sample.stop(Timer.builder("webClient.request")
                                .tags("method", request.method().name())
                                .tags("uri", request.url().toString())
                                .register(Metrics.globalRegistry));
                    }
                });
    }
}

WebClient customWebClient = customWebClientBuilder
        .filter(new CustomMetricsFilter())
        .build();

Mono<String> response = customWebClient.get()
        .uri("/api/endpoint")
        .retrieve()
        .bodyToMono(String.class);
