All Implemented Interfaces:

public class SpringComponentInjector
extends Injector
implements IComponentInstantiationListener, IBehaviorInstantiationListener

IComponentInstantiationListener that injects component and behavior properties annotated with SpringBean annotations. To install in yourapplication.init() call getComponentInstantiationListeners().add(new SpringComponentInjector(this));

Only Wicket Components and Behaviors are automatically injected, other classes such as Session, Model, and any other POJO can be injected by calling Injector.get().inject(this) in their constructor.
