Java 组合findAll、flatMap和Scheduler时缺少事件/项。boundedElastic（）

我在探索SpringWebFlux时编写了以下测试。 这很简单，我想。写10000条，然后再读一遍。 但不知何故，有时会有一些人失踪。 没有抛出异常，只是有时会遗漏一些异常。 这是一个编码错误还是mongo/reactor中的一个bug？ 这是一个基本的spring引导设置，无需进一步定制。 Thx

另外，请发布您的测试失败日志。

Flux

包含多个

Mono

，因此，请您向我解释为什么要在

Flux

中展开每个

Mono

，然后在

Mono

中重新包装，并对每个

boundedElastic

调度程序，因为这没有任何意义。文档明确指出，当有人订阅时，

subscribeOn

中应用的调度程序只应用一次，并且将使用链中第一个找到的调度程序。加上10000不会有任何区别。我想你需要仔细阅读反应堆文件。您可以直接删除整个

map

函数。我最初的意图是从存储库中构造一个域对象，这就是我遇到这个问题的地方。我知道这个例子毫无意义，但我尽可能地简化了它，仍然显示了不希望出现的结果。你肯定是对的，我必须读更多的书，更重要的是理解更多。所以请放心，我非常感谢你的回答。毕竟，我可能完全误用了API。正如我所说，刚刚开始探索。我添加了日志，无法粘贴断言错误，太长，开始：org.opentest4j.assertionfailederor:expected:但是：
