    // MQTT的连接设置

    MqttConnectOptions connectOption = new MqttConnectOptions();// MQTT参数
    // 设置是否清空session,这里如果设置为false表示服务器会保留客户端的连接记录，这里设置为true表示每次连接到服务器都以新的身份连接
    connectOption.setCleanSession(false);
    // 设置连接的用户名
    connectOption.setUserName(socketKey);
    connectOption.setServerURIs(new String[]{serverUrl});

    connectOption.setConnectionTimeout(15);
