Spring Dynamic Modules
Aus Eniak
Spring Dynamic Modules for OSGi(tm) Service Platforms (so der vollständige Name dieses Projektes) soll es ermöglichen Spring Anwendungen in einem OSGi Framework laufen zu lassen.
Wichtige Methoden
Wandelt ein BundleEvent in den Namen des Events um (STARTING, STARTED, STOPPING, ...):
OsgiStringUtils.nullSafeToString(bundleEvent)
Kleines Beispiel
Um das kleine Spring-DM Beispiel „simple-service-bundle“ zum Laufen zu kriegen muss man folgende Bundles bereitstellen:
Diese Bundles erfüllen quasi die Minimalanforderungen. Zu beachten ist, dass beim Download von Spring-OSGi Milestone 3 das Bundle „aopalliance.osgi-1.0-SNAPSHOT.jar“ fehlt. Es muss am besten mit Maven selber gebaut werden. Dazu Quellen runterladen und mvn clean install eingeben.
Die Konsole von Equinox sieht dann so aus (das Problem mit log4j konnte ich noch nicht lösen):
