  调用流程和相关注意点可以看这里：https://sns.bladex.cn/q-14847.html

  
  

  你的提问信息太少，还需要提供类似如下信息：
   1. 是不是跑的官方的原版工程，改动了哪些逻辑

   2. 跑了哪些服务，用的是单机版还是集群版还是emqx版

   3. 调试认证逻辑，可以全局搜索 MqttAuthServiceImpl ，点进去后找到对应的hasAuth的逻辑就可以了 (两个文件分别对应broker和emqx服务的认证类)

  1、为了测试规则引擎，昨天刚下载的新版本。

  2、本地启动的是server、broker模块。

  3、采用密码方式：

  

  4、后台报错信息：
