Hey guys,
I've personally been burned a couple times now by adding a dependency that
I really shouldn't have, but because that dependent had a default
constructor, Guice let me get away with it, leaving me to sort out the
rather bizarre consequences. I didnt really mind since I'd learned my
lesson, but as the project goes forward configuring guice is becoming an
increasingly common dev task, so I'd like to shield me and my team from
this bug in the future, since, in our configuration, it's fairly easy to
run into.
What I'd like is something along these lines:
public class ModelObjectThatHasSensitiveLifeCycle{
@NeverInject
public ModelObjectThatHasSensitiveLifeCycle(){
}
}
The idea being that, upon seeing the @NeverInject constructor, guice will
refuse to instance it, giving an error message to the effect of "bind a
custom provider or supply an existing instance".
I suppose I could use static factory that just hits a private default
constructor, but I dont really like imposing a convention on our devs
because a library wont cooperate, I'd rather have an annotation that speaks
directly to the problem. Further conventions aren't as strong as red
characters in std:err.
I've tried using your the introspection SPI to do what I'm looking for, but
I'm a little lost on your domains terminology, so I think I'm throwing in
the towel.
Heres a little bit of code I'd like to be able to run if I could manage it:
