如何使用Spring 5 Webclient打印原始HTTP请求和HTTP响应？

import org.springframework.http.HttpHeaders;
import org.springframework.http.HttpRequest;
import org.springframework.http.HttpStatus;
import org.springframework.http.client.reactive.ClientHttpRequest;
import org.springframework.http.client.reactive.ClientHttpResponse;
import org.springframework.web.reactive.function.client.ExchangeFilterFunction;
import reactor.core.publisher.Mono;

public class LoggingFilter implements ExchangeFilterFunction {
    @Override
    public Mono<ClientResponse> filter(ClientRequest request, ExchangeFunction next) {
        // 打印原始HTTP请求
        System.out.println("Request: " + request.method() + " " + request.url());
        HttpHeaders headers = request.headers();
        headers.forEach((name, values) -> values.forEach(value -> System.out.println(name + ": " + value)));

        // 发送请求并获取响应
        Mono<ClientResponse> responseMono = next.exchange(request);

        // 打印原始HTTP响应
        return responseMono.flatMap(response -> {
            System.out.println("Response: " + response.statusCode());
            HttpHeaders responseHeaders = response.headers();
            responseHeaders.forEach((name, values) -> values.forEach(value -> System.out.println(name + ": " + value)));
            return Mono.just(response);
        });
    }
}

import org.springframework.web.reactive.function.client.WebClient;

public class ExampleClient {
    public static void main(String[] args) {
        WebClient client = WebClient.builder()
                .filter(new LoggingFilter())
                .build();

        client.get()
                .uri("https://example.com/api")
                .retrieve()
                .bodyToMono(String.class)
                .subscribe(System.out::println);
    }
}
