Eclipse4/RCP/EAS/OSGi Services

The Eclipse 4 dependency injection framework exposes OSGi services for consumption to clients by default. This removes a lot of the boilerplate ServiceTracker code and allows clients to simply annotate a field to have an OSGi service injected.

OSGi APIs

public class Model {
 
  private EventAdmin eventAdmin;
 
  public Model(BundleContext ctxt) {
    ServiceTracker tracker = new ServiceTracker<EventAdmin, EventAdmin>(ctxt, EventAdmin.class, null);
    tracker.open();
    eventAdmin = tracker.getService();
  }
}

Eclipse 4 Dependency Injection

public class Model {
  @Inject
  private EventAdmin eventAdmin;
}
