Comment #3 on issue 353 by tregubov: Strange behavior on Inject Injector
instance in Constructor
http://code.google.com/p/google-guice/issues/detail?id=353
I create little Example with BAG. You can see it in attachment.
You can reproduce the Bag here
static class ChildService1Impl implements ChildService1
{
@Inject
public ChildService1Impl(Injector injector) /*BAG*/
// public ChildService1Impl(Injector injector,ChildService2Impl
childService2)
/*ALL WORK*/
{
System.out.println(injector.getParent());
}
}
When You in /*BAG*/ version you got null in System.out. Mean Root Injector
But when you run /*ALL WORK*/ version you got
Injector[bindings=[ProviderInstanceBinding[key=Key[type=com.google.inject.Injector,
annotation=[none]], source=[unknown source], scope=Scopes.NO_SCOPE,
provider=Provider<Injector>],
ProviderInstanceBinding[key=Key[type=java.util.logging.Logger,
annotation=[none]],
source=[unknown source], scope=Scopes.NO_SCOPE, provider=Provider<Logger>],
InstanceBinding[key=Key[type=com.google.inject.Stage, annotation=[none]],
source=[unknown source], instance=DEVELOPMENT],
ProviderInstanceBinding[key=Key[type=ru.faulab.fmsgenerator.GuiceBagExample$IRootServ
iceFactory, annotation=[none]],
source=ru.faulab.fmsgenerator.GuiceBagExample$RootSubModule1.configure(GuiceBagExampl
e.java:52), scope=Scopes.SINGLETON,
provider=ru.faulab.fmsgenerator.GuiceBagExample$IRootServiceFactory for
ru.faulab.fmsgenerator.GuiceBagExample$IRootServiceImpl],
LinkedKeyBinding[key=Key[type=ru.faulab.fmsgenerator.GuiceBagExample$IRootService2,
annotation=[none]],
source=ru.faulab.fmsgenerator.GuiceBagExample$RootSubModule2.configure(GuiceBagExampl
e.java:60), scope=Scopes.SINGLETON,
target=Key[type=ru.faulab.fmsgenerator.GuiceBagExample$IRootService2Impl,
annotation=[none]]]]] in System Out. Mean Child Injector
