Constructor Detail

NotificationListeningMessageProducer

public NotificationListeningMessageProducer()

Method Detail

setServer

public void setServer(MBeanServerConnection server)

Provide a reference to the MBeanServer where the notification publishing MBeans are registered.

Parameters:

server - the MBean server connection.

setObjectName

public void setObjectName(ObjectName... objectNames)

Specify the JMX ObjectNames (or patterns) of the notification publisher to which this notification listener should be subscribed.

Parameters:

objectNames - The object names.

setFilter

public void setFilter(NotificationFilter filter)

Specify a NotificationFilter to be passed to the server when registering this listener. The filter may be null.

Parameters:

filter - The filter.

setHandback

public void setHandback(Object handback)

Specify a handback object to provide context to the listener upon notification. This object may be null.

Parameters:

handback - The object.

handleNotification

public void handleNotification(Notification notification,
                               Object handback)

Notification handling method implementation. Creates a Message with the JMX Notification as its payload, and if the handback object is not null, it sets that as a Message header value. The Message is then sent to this producer's output channel.

Specified by:

handleNotification in interface NotificationListener

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 IntegrationObjectSupport

onApplicationEvent

public void onApplicationEvent(ContextRefreshedEvent event)

The NotificationListener might not be registered on AbstractEndpoint.start() because the MBeanExporter might not been started yet.

Specified by:

onApplicationEvent in interface ApplicationListener<ContextRefreshedEvent>

Parameters:

event - the ContextRefreshedEvent event

doStart

protected void doStart()

Registers the notification listener with the specified ObjectNames.

Overrides:

doStart in class MessageProducerSupport

doStop

protected void doStop()

Unregisters the notification listener.

Overrides:

doStop in class MessageProducerSupport

retrieveMBeanNames

protected Collection<ObjectName> retrieveMBeanNames()
