使用这个类发送P2P消息通信 MQTTSendP2PMessage.class 重现步骤 1.启动MQTTSendP2PMessage连接mqtt 2.启动设备A 3.MQTTSendP2PMessage正常与设备A通信 4.断开MQTTSendP2PMessage服务所在电脑网络 5.隔5秒后重新接通网络 6.即打印如下错误，只能重启MQTTSendP2PMessage服务才能正常通信 org.eclipse.paho.client.mqttv3.MqttException: 客户机未连接 at org.eclipse.paho.client.mqttv3.internal.ExceptionHelper.createMqttException(ExceptionHelper.java:31) at org.eclipse.paho.client.mqttv3.internal.ClientComms.sendNoWait(ClientComms.java:205) at org.eclipse.paho.client.mqttv3.MqttAsyncClient.publish(MqttAsyncClient.java:1375) at org.eclipse.paho.client.mqttv3.MqttClient.publish(MqttClient.java:570)

还有这种错误，可能是网络有点波动引起的，程序并未检测到连接断开
