Class InjectorHolder

java.lang.Object
  org.apache.wicket.injection.web.InjectorHolder

public class InjectorHolder
extends Object

Holds a reference to the injector that will be used to automatically initialize components that are used. Usually the application class should set the injector in the holder when it initializes.

This class can be used for unit-testing to switch the standard injector with an injector that will lookup dependencies from a mock application context.

 class MockSpringInjector extends SpringInjector
 {
        protected ISpringContextLocator getContextLocator()
        {
                return new MockContextLocator();
        }
 }
 
 InjectorHolder.setInjector(new MockSpringInjector());
 
 // from this point on InjectableWebPage and InjectablePanel
 // will be injected using the MockSpringInjector
