Class SpringConfiguredContainerFactory

java.lang.Object

com.neurosys.site.wicket.service.ContainerFactory

com.neurosys.site.wicket.service.SpringConfiguredContainerFactory

All Implemented Interfaces:

Serializable

@Component(value="defaultContainerFactory")
public class SpringConfiguredContainerFactory
extends ContainerFactory

Based on the class name of the Panel being injected, and optionally its parent

One can obtain an instance of it by:
private SpringConfiguredContainerFactory factory = AppSettings.get().WICKET_CONTAINER_FACTORY; or private SpringConfiguredContainerFactory factory = AppSettings.get()springContext.getBean(SpringConfiguredContainerFactory.class);

Uses the deriveId(MarkupContainer); to determine the name in the Spring configs (properties). The property would be namespace + Class.getName(). If the class is an anonymous class then the super Class.getName() is used. TODO: Build an annotation alternative to the factory, which at RUNTIME scans a wicket parent and replaces its child with the overriding component.
TODO: Allow proxy of base implementations, so that any anonymous overrides in the original implementation can be preserved by the factory.
