Injecting values into a bean provided by @Provides

[zonski]

If I bind my bean using either of the following:

bind(MyInterface.class).to(MyInterfaceImpl.class);

or

bind(MyInterface.class).toInstance(new MyInterfaceImpl());

The resulting bean will have all it's fields marked with @Inject
automatically injected, just as I'd expect.

However if I use an @Provides marked method to do exactly the same
thing then my fields are not injected:

// resulting bean is not injected?
@Provides public MyInterface myInterface() {
return new MyInterfaceImpl();
}

This seems a bit odd for me. I'm guessing this is done to allow
developers to control the wiring for their provided classes, but in my
case I don't want to control this, I just want to control how the bean
gets instantiated (because in my real scenario I actually have to load
my bean from an XML file) and have Guice still do all the autowiring.

Is this really not possible?

You could inject the Injector into your method and call Injector.injectMembers(bean);

Thanks Willi, that solved my problem! I was looking for a simple annotation or annotation parameter (which would still seem nicer, but I can live with it) so I was heading down the wrong path.

Cheers!
