（1）为什么写这个话题（Why）读万卷书不如行千里路。这次搭建MQTT服务，遇到了一些误解，特此记录备忘。主要包括：（1）服务（Broker）的账户管理与网页管理平台的账户（2）与web应用的集成（Spring系）（2）ActiveMQ版本选择因为JAVA环境是JDK8，所以按兼容性考虑选择了ActiveMQ5.15的最后版本5.15.15。如果你是JDK11则可考虑ActiveMQ的最新版本5.17或5.18。ActiveMQ支持MQTTv3.1.1andv3.1。（3）ActiveMQ与web应用的集成主要介绍与Spring系的webapp集成（SpringBoot和SpringMVC）。
