Hey, I have a question about heritage and CDI.
Given two interfaces:
- Car interface
- SportCar that extends Car
interface Car{}
interface SportCar extends Car{}
class DefaultCar implements Car {}
@FerrariQualifierclass DefaultSportCar implements SportCar {}
What I would like to inject:
@Injectprivate Car car; //inject DefaultCar
@Inject
@FerrariQualifierprivate Car ferrari; //inject DefaultSportCar
@Injectprivate SportCar sportCar;//inject DefaultSportCar
How can I do that?

Hi Otavio
Not sure it firts cdi-dev bit you can @Default @Ferrari
@Typed(SportCar.class) the nice red car to exclude it from Car type and
keep Car injection using DefaultCar and SportCar using the ferrari or
implicit default qualifier.
But the sample sounds like a misusage of qualifier so maybe check it is
really what you and to do.

Hi all,
I think Romain's workaround would not work for the second injection
point, i.e. for @Inject @FerrariQualifier Car ferrari because
@Typed(SportCar.class) DefaultSportCar would remove the Car from the
bean types of DefaultSportCar.
I agree that it looks like an incorrect usage of qualifiers though.
