moduł GIN:GWT GIN - trywialne use-case nie powiedzie się (EventBus)
public class InjectorModule extends AbstractGinModule {
@Override
protected void configure() {
bind(EventBus.class).to(SimpleEventBus.class).in(Singleton.class);
}
}
Injector:
@GinModules(InjectorModule.class)
public interface Injector extends Ginjector {
EventBus getEventBus();
}
GWT punkt wejścia Moduł:
public class Module1 implements EntryPoint {
private final Injector injector = GWT.create(Injector.class);
public void onModuleLoad() {
injector.getEventBus();
}
}
Usuwanie wezwanie do injector.getEventBus()
make wszystko działa dobrze. Zadzwoń do injector.getEventBus()
przyczyn:
