Constructor Details

NotificationPublishingMessageHandler

public NotificationPublishingMessageHandler(ObjectName objectName)

Construct an instance based on the provided object name.

Parameters:

objectName - the ObjectName to use for notification.

NotificationPublishingMessageHandler

public NotificationPublishingMessageHandler(String objectName)

Construct an instance based on the provided object name.

Parameters:

objectName - the object name to use for notification.

Method Details

setNotificationMapper

public void setNotificationMapper(@Nullable
 OutboundMessageMapper<Notification> notificationMapper)

Set a mapper for creating Notifications from a Message. If not provided, a default implementation will be used such that String-typed payloads will be passed as the 'message' of the Notification and all other payload types will be passed as the 'userData' of the Notification.

Parameters:

notificationMapper - The notification mapper.

setDefaultNotificationType

public void setDefaultNotificationType(String defaultNotificationType)

Specify a dot-delimited String representing the Notification type to use by default when no explicit Notification mapper has been configured. If not provided, then a notification type header will be required for each message being mapped into a Notification.

Parameters:

defaultNotificationType - The default notification type.

getComponentType

public String getComponentType()

Description copied from class: IntegrationObjectSupport

Subclasses may implement this method to provide component type information.

Specified by:

getComponentType in interface NamedComponent

Overrides:

getComponentType in class MessageHandlerSupport

onInit

public final void onInit()

Description copied from class: IntegrationObjectSupport

Subclasses may implement this for initialization logic.

Overrides:

onInit in class IntegrationObjectSupport

handleMessageInternal

protected void handleMessageInternal(Message<?> message)

Specified by:

handleMessageInternal in class AbstractMessageHandler
