thingsboard学习笔记

安装指南：
https://thingsboard.io/docs/user-guide/install/installation-options/
1.初识
thingsboard安装在服务器中后，已经自带了mqtt服务器，不要在安装mqtt服务器
设备：设备凭证中使用access token
真实设备采集数据后，可以通过mqtt上传至此设备，通过access token识别。例如我们通过Mqtt fx客户端发送数据模拟的时候user name就是这个access token，密码不需要。

2.测试
thingsboard一般需要配合thingsboard-gateway网关
安装：https://github.com/thingsboard/thingsboard-gateway/releases/tag/2.7

网关中MQTT配置，broker代表自己部署的MQTT服务器，不是thingsboard中的MQTT

3.Topic主题映射过滤器
例如：主题为/sensor/TestDevice/data，实际在java中测试发送的主题(.替换/)Topic：.sensor.TestDevice.data
发送数据
{ “sensorType”: “Thermometer”,“sensorModel”:“T1000”, “temp”:75256,“hum”:75257}
设备发送数据到MQTT服务器后，在仪表板可以看到数据如下
