public Mqttv5PahoMessageHandler(org.eclipse.paho.mqttv5.client.MqttConnectionOptions connectionOptions,
 String clientId)

Mqttv5PahoMessageHandler

public Mqttv5PahoMessageHandler(ClientManager<org.eclipse.paho.mqttv5.client.IMqttAsyncClient,org.eclipse.paho.mqttv5.client.MqttConnectionOptions> clientManager)

Use this constructor when you need to use a single ClientManager (for instance, to reuse an MQTT connection).

Parameters:

clientManager - The client manager.

Since:

6.0

Method Details

getConnectionInfo

public org.eclipse.paho.mqttv5.client.MqttConnectionOptions getConnectionInfo()

Description copied from interface: MqttComponent

Return information about the connection.

Specified by:

getConnectionInfo in interface MqttComponent<org.eclipse.paho.mqttv5.client.MqttConnectionOptions>

Returns:

the information.

setPersistence

public void setPersistence(@Nullable
 org.eclipse.paho.mqttv5.client.MqttClientPersistence persistence)

setHeaderMapper

public void setHeaderMapper(org.springframework.integration.mapping.HeaderMapper<org.eclipse.paho.mqttv5.common.packet.MqttProperties> headerMapper)

setAsync

public void setAsync(boolean async)

Set to true if you don't want to block when sending messages. Default false. When true, message sent/delivered events will be published for reception by a suitably configured 'ApplicationListener' or an event inbound-channel-adapter.

Parameters:

async - true for async.

See Also:

• setAsyncEvents(boolean)

setAsyncEvents

public void setAsyncEvents(boolean asyncEvents)

When setAsync(boolean) is true, setting this to true enables publication of MqttMessageSentEvent and MqttMessageDeliveredEvent to be emitted. Default false.

Parameters:

asyncEvents - the asyncEvents.
