Behind the Scenes (=Magic) of Dependency Injection in Quarkus 📎
Why the injection of @RequestScoped beans is in
quarkus so fast?
The short answer is:
public HelloResource create(final CreationalContext creationalContext) {
final HelloResource helloResource = new HelloResource();
try {
final InjectableReferenceProvider value = this.injectProviderSupplier1.get();
helloResource.hello = (Hello)value.get((CreationalContext)CreationalContextImpl.child((InjectableReferenceProvider)value, creationalContext));
}
catch (RuntimeException ex) {
throw new RuntimeException("Error injecting airhacks.Hello airhacks.HelloResource.hello", ex);
}
helloResource.initResource();
return helloResource;
}
