public class MqttPahoMessageDrivenChannelAdapter
extends AbstractMqttMessageDrivenChannelAdapter
implements org.eclipse.paho.client.mqttv3.MqttCallback, MqttPahoComponent

Eclipse Paho Implementation. When consuming MqttIntegrationEvents published by this component use MqttPahoComponent adapter = event.getSourceAsType() to get a reference, allowing you to obtain the bean name and MqttConnectOptions. This technique allows consumption of events from both inbound and outbound endpoints in the same event listener.

Since:

4.0
