Class SpringComponentInjector

java.lang.Object

org.apache.wicket.injection.Injector

org.apache.wicket.spring.injection.annot.SpringComponentInjector

All Implemented Interfaces:

IComponentInstantiationListener, IBehaviorInstantiationListener

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.

Parameters:

webapp - wicket web application

SpringComponentInjector

public SpringComponentInjector(WebApplication webapp,
 org.springframework.context.ApplicationContext ctx)

Constructor

Parameters:

webapp - wicket web application

ctx - spring's application context

SpringComponentInjector

public SpringComponentInjector(WebApplication webapp,
 org.springframework.context.ApplicationContext ctx,
 boolean wrapInProxies)

Constructor

Parameters:

webapp - wicket web application

ctx - spring's application context

wrapInProxies - whether or not wicket should wrap dependencies with specialized proxies that can be safely serialized. in most cases this should be set to true.

Method Details

inject

public void inject(Object object)

Description copied from class: Injector

Injects the specified object. This method is usually implemented by delegating to Injector.inject(Object, IFieldValueFactory) with some IFieldValueFactory

Specified by:

inject in class Injector

See Also:

• Injector.inject(Object, IFieldValueFactory)

onInstantiation

public void onInstantiation(Component component)

Description copied from interface: IComponentInstantiationListener

Called for every component that is instantiated. This method is called during construction, so do not depend on the construction being completed yet. The id is guaranteed to be set before this call.

Specified by:

onInstantiation in interface IComponentInstantiationListener

Parameters:

component - the component that is being instantiated.

onInstantiation

public void onInstantiation(Behavior behavior)

Description copied from interface: IBehaviorInstantiationListener

Called when a behavior instance is created

Specified by:

onInstantiation in interface IBehaviorInstantiationListener

setDefaultContext

public static void setDefaultContext(WebApplication webapp,
 org.springframework.context.ApplicationContext context)

Set the default context for the given webapp.

Parameters:

webapp - web application

context - context to use as default if non is explicitely specified for the injector
