Класс Javax @Singleton не получает инъекцию (null)

Question

@Singleton //This is the class I want to be injected
public class Helpers {
    Helpers helpers;
    @Inject
    public Helpers getInstance(){
        if(helpers != null)
            return new Helpers();
        return helpers;
    }
    @PostConstruct
    public void init() {
        System.out.println("######## CREATED #######");
    }
}


class consumer{
 @Inject
 Helpers help;
 public void hi(){
  System.out.print(help.tostring());
}
public static void main(String args[]){
   new Consumer().hi() // get null pointer exception
}

}
