Question

我正在使用React core进行整理并尝试创建＆＃39; hot无限的＆＃39;有多个订户的流量：

@Test
public void hotStream() throws InterruptedException {

  AtomicInteger counter = new AtomicInteger();

  Flux<Object> flux = Flux
      .create(fluxSink -> {
        while (counter.incrementAndGet() <= 10) {
          try {
            TimeUnit.MILLISECONDS.sleep(100);
          } catch (InterruptedException ignored) {
          }
          fluxSink.next(System.currentTimeMillis());
        }
      }).log()
      .publish()
      .autoConnect();

  // first subscriber
  new Thread(() -> {
    log.info("[S] Subscribing first");
    flux.log().subscribe(s -> log.info("[*] S1: {}", s));
  }).start();

  Thread.sleep(450);

  // second subscriber
  new Thread(() -> {
    log.info("[S] Subscribing second");
    flux.log().subscribe(s -> log.info("[*] S2: {}", s));
  }).start();
}

但是当第二个订户订阅了磁通时，那么进程正在停止：

我预计第二个订阅者将开始与第一个订阅者一起阅读流。但这不会发生。

可以请某人解释为什么会这样，以及如何解决它？

已更新

我所要做的就是在测试结束时添加以下行以防止它停止：

Thread.currentThread().join();

Reactor core：无限Flux不适用于多个订阅者
