Simple interface allowing Spring-managed MBeans to publish JMX notifications without being aware of how those notifications are being transmitted to the javax.management.MBeanServer.

Managed resources can access a NotificationPublisher by implementing the NotificationPublisherAware interface. After a particular managed resource instance is registered with the javax.management.MBeanServer, Spring will inject a NotificationPublisher instance into it if that resource implements the NotificationPublisherAware interface.

Each managed resource instance will have a distinct instance of a NotificationPublisher implementation. This instance will keep track of all the NotificationListeners registered for a particular managed resource.

Any existing, user-defined MBeans should use standard JMX APIs for notification publication; this interface is intended for use only by Spring-created MBeans.
