本文整理了Java中reactor.core.publisher.Flux.thenMany()方法的一些代码示例，展示了Flux.thenMany()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Flux.thenMany()方法的具体详情如下：
包路径：reactor.core.publisher.Flux
类名称：Flux
方法名：thenMany

Flux.thenMany介绍

[英]Let this Flux complete then play another Publisher.

In other words ignore element from this flux and transform the completion signal into a Publisher that will emit elements from the provided Publisher.
[中]让此流量完成，然后播放另一个发布者。
换句话说，忽略此流量中的元素，并将完成信号转换为发布服务器，该发布服务器将从提供的发布服务器发出元素。
