如何在出错的Spring WebFlux上调用另一个接口

import org.springframework.web.reactive.function.client.WebClient;
import reactor.core.publisher.Mono;

public class Example {
    public static void main(String[] args) {
        WebClient webClient = WebClient.create();

        // 发起原始接口请求
        Mono<String> response = webClient.get()
                .uri("https://example.com/api")
                .retrieve()
                .bodyToMono(String.class);

        // 处理异常并调用备用接口
        Mono<String> fallbackResponse = response.onErrorResume(throwable -> {
            // 异常处理逻辑
            System.out.println("原始接口请求出错：" + throwable.getMessage());

            // 创建备用接口请求
            WebClient fallbackClient = WebClient.create();
            Mono<String> fallbackRequest = fallbackClient.get()
                    .uri("https://example.com/fallback-api")
                    .retrieve()
                    .bodyToMono(String.class);

            return fallbackRequest;
        });

        // 处理备用接口的响应
        fallbackResponse.subscribe(
                result -> System.out.println("备用接口响应：" + result),
                error -> System.out.println("备用接口请求出错：" + error.getMessage())
        );
    }
}
