[weld-dev] What is the best way to pass cofiguration to CDI bean using Weld?

[Mark Struberg]

you could look at Apache DeltaSpike @Configuration and he whole DS config mechanism.
http://deltaspike.apache.org/documentation/configuration.html
It's battle proven and also the origin of microprofile-config and JSR-382.Runs on anything EE6 ++, from Java7 to Java10

 Hi Alex,

Not sure if I get what you need to do, but I'll take a shot at it.
What about using @PostConstruct interceptor, in which you take the injected Application bean and use it to set internal state in SomeManagerImpl?
Same could be done directly within constructor (with @Inject annotation) or an initializer method.

E.g.

@ApplicationScoped
public class SomeManagerImpl implements SomeManager{} {

 private MyConfiguration config;

 @Inject
 Application app;

 @PostConstruct
 public void doSomeInit() {
  config = app.getConfig(); // get config from Application and appply here
 }
}

If I misunderstood your question, please correct me :)
