使用WebClient结合Flux实现并行调用多个互不相关的http请求，并使结果按照调用顺序返回

import java.util.List;

@Service

        this.webClient = webClientBuilder.baseUrl("http://example.com").build();
    }

    public Mono<List<String>> makeDynamicRequests(List<String> endpoints) {
        // 发起 HTTP 请求并收集结果到 List
        return Flux.fromIterable(endpoints)
                .flatMap(endpoint -> webClient.get().uri(endpoint).retrieve().bodyToMono(String.class))
                .collectList(); // 收集结果到 List 中，保持顺序不乱
    }
