在发布者和订阅者之间存在时间依赖性，发布者需要创建一个订阅（subscription），以便客户能够订阅；订阅者必须保持在线状态以接收消息；当然，如果订阅者创建了持久的订阅，那么在订阅者未连接时，消息生产者发布的消息将会在订阅者重新连接时重新发布...Apache Qpid Apache ActiveMQ RabbitMQ 可能有小伙伴奇怪咋还有 ActiveMQ？其实 ActiveMQ 不仅支持 JMS，也支持 AMQP，这个松哥后面细说。...重要产品 2.1 ActiveMQ ActiveMQ 是 Apache 下的一个子项目，使用完全支持 JMS1.1 和 J2EE1.4 规范的 JMS Provider 实现，少量代码就可以高效地实现高级应用场景...现在的 ActiveMQ 分为两个版本： ActiveMQ Classic ActiveMQ Artemis 这里的 ActiveMQ Classic 就是原来的 ActiveMQ，而 ActiveMQ...因此大家在使用时，建议直接选择 ActiveMQ Artemis。
