原因是Thingsboard Gateway依赖的Thingsboard的版本不匹配
解决方案参考官方Issue：https://github.com/thingsboard/thingsboard-gateway/issues/26#issuecomment-381832965
首先，我们已经有了Thingsboard的开发环境，查看一下Thingsboard版本，这里是2.3.1
修改Thingsboard Gateway源码中的pom.xml文件，记得也修改为2.3.1
再次尝试编译
等待几分钟最终编译成功
编译成功后，在源码的目录下会生成target文件夹，里面的文件即是打包好的结果
其中tb-gateway-windows.zip是针对Windows平台的安装包
目前的状态如下
启动Thingsboard（在运行Thingsboard Gateway前，假使你已经知道了Thingsboard平台是如何运行的，也已经正常的编译成功源代码了）
使用租户管理员，登陆到系统，并创建一个设备，并指定为网关
进入到设备的属性中，将Access Token复制出来备用
目前的状态如下
Windows尝试安装Thingsboard Gateway，首先解压文件
打开Thingsboard Gateway目录下conf配置文件
修改配置文件内容
就使用刚才编译代码时的管理员身份打开的命令行窗口
#进入到指定的目录
cd target\tb-gateway-windows\tb-gateway
#安装网关服务
install.bat
#开始网关服务
net start tb-gateway运行截图
目前的状态如下
进入到Thingsboard，查看网关的最后遥测数据，只要出现以下参数变为0，即Thingsboard Gateway与Thingsboard平台已经连接上了
#All values should be set to “0”（以下三个属性应该都是0）
devicesOnline：0
attributesUploaded：0
telemetryUploaded：0浏览器界面
目前的状态如下
尝试一下Thingsboard Gateway的功能先，首先使用最常用的MQTT协议
为了测试，我在本机也搭建了一个mosquitto环境，另外，也修改了mosquitto的端口为1884（找到文件C:\Program Files\mosquitto\mosquitto.conf，找到节点port 1883，将1883修改成1884，并将前面的#删除，重启mosquitto服务让配置生效）
官方参考配置文件地址：https://thingsboard.io/docs/iot-gateway/resources/mqtt-gui-extension-configuration.json

进入到Thingsboard的网关中，查看配置，点击上传
将下载的json配置文件拖动到上传框，并点击上传
可以看到网关的状态为同步状态
查看其中的配置内容，请留意，现在的MQTT服务器是127.0.0.1，端口是1884，使用的就是本机安装mosquitto服务器
MQTTBox（下载地址：http://workswithweb.com/mqttbox.html）
创建一个连接，直接连接到本机的mosquitto上
然后在MQTTBox上发布一条消息，点击发送
#主题
sensors
#消息体
{"serialNumber":"SN-001", "model":"T1000", "temperature":36.6}
刷新Thingsboard设备的列表，可以看到多了一个SN-001的设备
并且新加入的设置也是有遥测值的
新设备与网关进行了关联
如果需要设置设备在线或离线状态，需要发送主题sensor/设备编号/connect（离线，需要发送主题sensor/设备编号/disconnect）
目前的状态如下
即然本地MQTT Broker是可以的，那么远程的MQTT Broker呢？是否可用呢
在Thingsboard中修改网关的MQTT设置，并保存
再次使用MQTTBox测试
在Thingsboard设备列表中又增加了SN-002的设备，且已经有了遥测值
提醒，这里提醒一下，Thingsboard Gateway需要与Thingsboard配套使用，如果版本不同，则无法进行处理
最终理想的状态
