Dagger -如何在服务和片段之间共享所提供的对象？

import javax.inject.Scope;

@Scope
@Retention(RetentionPolicy.RUNTIME)
public @interface ServiceScope {
}

import dagger.Module;
import dagger.Provides;

@Module
public class MyModule {

    @ServiceScope
    @Provides
    public MySharedObject provideMySharedObject() {
        return new MySharedObject();
    }
}

import dagger.Component;

@Component(modules = MyModule.class)
@ServiceScope
public interface MyComponent {
    void inject(MyService service);
    void inject(MyFragment fragment);
}

import javax.inject.Inject;

public class MyService extends Service {

    @Inject
    MySharedObject mySharedObject;

    @Override
    public void onCreate() {
        super.onCreate();
        DaggerMyComponent.builder()
                .myModule(new MyModule())
                .build()
                .inject(this);
    }
}

import javax.inject.Inject;

public class MyFragment extends Fragment {

    @Inject
    MySharedObject mySharedObject;

    @Override
    public void onAttach(Context context) {
        super.onAttach(context);
        DaggerMyComponent.builder()
                .myModule(new MyModule())
                .build()
                .inject(this);
    }
}
