Class GuiceComponentInjector

java.lang.Object

org.apache.wicket.injection.Injector

org.apache.wicket.guice.GuiceComponentInjector

All Implemented Interfaces:

IComponentInstantiationListener, IBehaviorInstantiationListener

public class GuiceComponentInjector
extends Injector
implements IComponentInstantiationListener, IBehaviorInstantiationListener

Injects field members of components and behaviors using Guice.

Add this to your application in its Application.init() method like so:

 getComponentInstantiationListeners().add(new GuiceComponentInjector(this));
 

There are different constructors for this object depending on how you want to wire things. See the javadoc for the constructors for more information.

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.

Constructor Detail

GuiceComponentInjector

public GuiceComponentInjector(Application app)

Creates a new Wicket GuiceComponentInjector instance.

Internally this will create a new Guice Injector instance, with no Module instances. This is only useful if your beans have appropriate ImplementedBy annotations on them so that they can be automatically picked up with no extra configuration code.

Parameters:

app -

GuiceComponentInjector

public GuiceComponentInjector(Application app,
                      com.google.inject.Module... modules)

Creates a new Wicket GuiceComponentInjector instance, using the supplied Guice Module instances to create a new Guice Injector instance internally.

Parameters:

app -

modules -

GuiceComponentInjector

public GuiceComponentInjector(Application app,
                      com.google.inject.Injector injector)

Constructor

Parameters:

app -

injector -

GuiceComponentInjector

public GuiceComponentInjector(Application app,
                      com.google.inject.Injector injector,
                      boolean wrapInProxies)

Creates a new Wicket GuiceComponentInjector instance, using the provided Guice Injector instance.

Parameters:

app -

injector -

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.
