使用Spring 5.0 WebClient进行异步调用将抛出连接，但成功调用很少

Question

我正在尝试通过WebClient发出异步发布请求，因为这是使用Springframework 5.0时的首选方式。

这是我的服务器代码：

我拥有的客户端代码是：

package com.example.demo;

import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.extern.slf4j.Slf4j;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.http.MediaType;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RestController;

@SpringBootApplication
@RestController
@Slf4j
public class DemoApplication {

    public static void main(String[] args) {
        SpringApplication.run(DemoApplication.class, args);
    }

    @PostMapping(value = "/createCustomer", produces = MediaType.APPLICATION_JSON_UTF8_VALUE, consumes = "text/plain")
    public Customer sendStream(@RequestBody String number) throws InterruptedException {
        Thread.sleep(40);
        return new Customer(number, "random" + number);
    }

    @Data
    @AllArgsConstructor
    class Customer {
        String id;
        String name;
    }


}

在成功运行此代码后，出现以下异常。

    package com.example.demo2;

import lombok.extern.slf4j.Slf4j;
import org.springframework.boot.CommandLineRunner;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.web.reactive.function.BodyInserters;
import org.springframework.web.reactive.function.client.WebClient;
import reactor.core.publisher.Flux;
import reactor.core.scheduler.Schedulers;

import java.util.stream.IntStream;

@SpringBootApplication
@Slf4j
public class Demo2Application implements CommandLineRunner {


    public static void main(String[] args) {
        SpringApplication.run(Demo2Application.class, args);
    }


    @Override
    public void run(String... args) throws Exception {
        WebClient webClient = WebClient.create("http://localhost:8080");
        IntStream.range(0, 100000).forEach(i -> {
            Flux.merge(
                    webClient
                            .post()
                            .uri("/createCustomer")
                            .body(BodyInserters.fromObject(String.valueOf(i)))
                            .retrieve().bodyToMono(String.class)
            )
                    .parallel()
                    .runOn(Schedulers.single())
                    .subscribe(log::info);


        });

    }
}

我在做什么错，我试图限制线程数，但这没有帮助，在使用单线程的客户端代码中可以看到。

任何帮助将不胜感激。

这是一个错误吗？
