如何在阻塞的Spring MVC应用程序中进行并发WebClient调用？

@Controller
public class MyController {

    private final WebClient.Builder webClientBuilder;

    public MyController(WebClient.Builder webClientBuilder) {
        this.webClientBuilder = webClientBuilder;
    }

    @GetMapping("/concurrent-webclient")
    public Mono<String> concurrentWebClient() {
        WebClient webClient = webClientBuilder.build();

        Mono<String> result1 = webClient.get()
                .uri("http://example.com/api/endpoint1")
                .retrieve()
                .bodyToMono(String.class);

        Mono<String> result2 = webClient.get()
                .uri("http://example.com/api/endpoint2")
                .retrieve()
                .bodyToMono(String.class);

        return result1.zipWith(result2, (r1, r2) -> r1 + " " + r2)
                .subscribeOn(Schedulers.parallel());
    }
}
