Я новичок в кустарнике. Я смог подготовить базовое приложение JAX-RS в рое и работал как шарм. Но когда я попытался ввести CDI в свое приложение, все пошло не так. Бин Инъекция не работает !. Я получаю NULLPointerException в тех местах, где я пытался использовать методы bean. Я пробовал все возможные решения, которые я мог найти через Интернет. Но ничего не получилось. Ниже приведена моя конфигурация pom.xml;Зависимость Инъекция, не работающая в Wildfly-Swarm-2016.12.1

и следующее мое заявление о ресурсах JAX-RS;
@Path("/handshake-test")

@Inject

*/
/*managedExecutorService.submit(() -> {
asyncResponse.resume("Hi World!!!.. This is Wildfly in CDI !!!");
});*/
asyncResponse.resume(authenticator.authenticate());
}
}
и следующие - фасоль аутентификатора;
@Stateless
public class Authenticator {
/**
*
*/
public Authenticator() {
// TODO Auto-generated constructor stub
}
public String authenticate() {
return "Authenticated !!";
}
}
Не вводится даже ManagedExectorService !. Может ли кто-нибудь помочь мне разобраться в этом?
Обновления с последней ошибкой получил, после попытки решения упоминаемого Кена

Hi Ken. Я пробовал это. Но все еще сталкиваются с проблемами. Я получаю эту проблему сейчас, и сервер не запускается. Я обновил вопрос с последней ошибкой, которую я получил. – JHermit
Привет Кен. Я изменил режим обнаружения bean-beans в beans.xml с «аннотированного» на «все», и он сработал! Спасибо за помощь. – JHermit
