使用spring boot项目反应器并行创建多个API调用，但不等待任何其他响应

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

public class ParallelApiCalls {

    private final WebClient webClient = WebClient.create();

    public Flux<String> callApisInParallel() {
        // 创建多个API调用的Mono实例
        Mono<String> api1 = webClient.get().uri("https://api1.example.com/data").retrieve().bodyToMono(String.class);
        Mono<String> api2 = webClient.get().uri("https://api2.example.com/data").retrieve().bodyToMono(String.class);
        Mono<String> api3 = webClient.get().uri("https://api3.example.com/data").retrieve().bodyToMono(String.class);

        // 使用Flux.merge并行执行所有调用
        return Flux.merge(api1, api2, api3);
    }

    public static void main(String[] args) {
        ParallelApiCalls caller = new ParallelApiCalls();
        caller.callApisInParallel()
              .subscribe(response -> System.out.println("Received response: " + response));
    }
}
