iot-mqtt

Release 1.0

本项目完全基于jmqtt项目https://github.com/Cicizz/jmqtt 修改。 目前只是对部分代码进行了梳理重构。去除了集群部分。 修正了一些bug。并加入简单的$SYS/实现 后期会加入原创的集群的实现。
现在已对mqtt3.1.1协议有完整的实现。 本项目默认采用rocksdb做消息的持久化,所以即使项目故障推出,也不会丢失数据,恢复项目后可以自动重连发送。 运行方法:

  • maven build 出相应jar包,放入release/bin(或者加QQ群682036712,有编译好的jar)。
  • cd release/bin目录 执行相应方法 ,相关配置在config目录下。
    1. server启动broker,默认1883端口,用户名admin密码123456。
    2. subscribe_test启动接受服务,默认监听/QOS0,/QOS1,/QOS2,三个主题。
    3. send_test启动发送服务,向/QOS0,/QOS1,/QOS2三个主题,并发1000个线程发送消息。
    4. subscribe_sys启动监控服务,默认监听$SYS/主题.并显示当前所有client信息,包含每个client 接受消息数,发送消息数,关注的主题,等信息。
