Guys,
I don't understand your answers. It sounds to me like you're talking
about field injection, not constructor injection.
I don't want to inject a log into an already-constructed object. I want
to inject a log directly into the class constructor:
class Foo
{
private final Logger log;
@Inject
public Foo(Logger log)
{
this.log = log;
}
}
Also, I am not necessarily doing this for jdk loggers so please provide
more detail on how to write a custom injection listener to do this.
Thanks,
Gili
