How to use

configureQualifier

method

in

javax.enterprise.inject.spi.BeforeBeanDiscovery

  public void observeBeforeBeanDiscovery(@Observes BeforeBeanDiscovery event) {
    // turn annotation into qualifier
    event.configureQualifier(CustomQualifier.class);
    
    // turn annotation into binding
    event.configureInterceptorBinding(CustomBinding.class);
  }
}

void letOtherExtensionsUseRegistries(@Observes final BeforeBeanDiscovery beforeBeanDiscovery, final BeanManager beanManager) {
  beforeBeanDiscovery.addQualifier(RegistryType.class);
  beanManager.fireEvent(applicationRegistry);
  beanManager.fireEvent(applicationRegistry, new RegistryTypeImpl(MetricRegistry.Type.APPLICATION));
  beanManager.fireEvent(baseRegistry, new RegistryTypeImpl(MetricRegistry.Type.BASE));
  beanManager.fireEvent(vendorRegistry, new RegistryTypeImpl(MetricRegistry.Type.VENDOR));
  // we make @Metric.name binding (to avoid to write producers relying on injection point)
  beforeBeanDiscovery.configureQualifier(org.eclipse.microprofile.metrics.annotation.Metric.class)
      .methods().stream().filter(method -> method.getAnnotated().getJavaMember().getName().equals("name"))
      .forEach(method -> method.remove(a -> a.annotationType() == Nonbinding.class));
}
