public class Mqttv5PahoMessageDrivenChannelAdapter extends AbstractMqttMessageDrivenChannelAdapter<org.eclipse.paho.mqttv5.client.IMqttAsyncClient,org.eclipse.paho.mqttv5.client.MqttConnectionOptions> implements org.eclipse.paho.mqttv5.client.MqttCallback, MqttComponent<org.eclipse.paho.mqttv5.client.MqttConnectionOptions>
The AbstractMqttMessageDrivenChannelAdapter implementation for MQTT v5.

The MqttProperties are mapped via the provided HeaderMapper; meanwhile the regular MqttMessage properties are always mapped into headers.

It is recommended to have the MqttConnectionOptions.setAutomaticReconnect(boolean) set to true to let an internal IMqttAsyncClient instance to handle reconnects. Otherwise, only the manual restart of this component can handle reconnects, e.g. via MqttConnectionFailedEvent handling on disconnection.

See setPayloadType(java.lang.Class<?>) for more information about type conversion.
