本文整理了Java中io.vertx.core.eventbus.Message.body()方法的一些代码示例，展示了Message.body()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。Message.body()方法的具体详情如下：
包路径：io.vertx.core.eventbus.Message
类名称：Message
方法名：body

Message.body介绍

[英]The body of the message. Can be null.
[中]信息的主体。可以为空。

代码示例

  eb.consumer("news-feed", message -> System.out.println("Received news on consumer 1: " + message.body()));
  
  eb.consumer("news-feed", message -> System.out.println("Received news on consumer 2: " + message.body()));
  
  eb.consumer("news-feed", message -> System.out.println("Received news on consumer 3: " + message.body()));

  System.out.println("Ready!");
