PubSubInboundChannelAdapter

public PubSubInboundChannelAdapter(PubSubSubscriberOperations pubSubSubscriberOperations,
                                   String subscriptionName)

Method Detail

getAckMode

public AckMode getAckMode()

setAckMode

public void setAckMode(AckMode ackMode)

setHealthTrackerRegistry

public void setHealthTrackerRegistry(HealthTrackerRegistry healthTrackerRegistry)

getPayloadType

public Class<?> getPayloadType()

setPayloadType

public void setPayloadType(Class<?> payloadType)

Set the desired type of the payload of the Message constructed by converting the incoming Pub/Sub message. The channel adapter will use the PubSubMessageConverter configured for PubSubSubscriberOperations.subscribeAndConvert(String, java.util.function.Consumer, Class). The default payload type is byte[].class.

Parameters:

payloadType - the type of the payload of the Message produced by the adapter. Cannot be set to null.

setHeaderMapper

public void setHeaderMapper(org.springframework.integration.mapping.HeaderMapper<Map<String,String>> headerMapper)
