The Spring DM provides the bundle listener interface Osgibundleapplicationcontextlistener

By using the monitoring interface provided by spring DM, we can better control the service, in fact, the interface is also very simple to use, as long as the custom of a class implementation of the Osgibundleapplicationcontextlistener interface, Implement the Onosgiapplicationevent method, and register the custom class as an OSGi service, perform the appropriate logic processing by judging the event type of events, and also obtain the bundles that are currently listening, thus achieving deeper monitoring.
