How to inject @EJB, @PersistenceContext, @Inject, @Autowired, etc in @FacesConverter?

Question

How can I inject a dependency like @EJB, @PersistenceContext, @Inject, @AutoWired, etc in a @FacesConverter?

Answer 1

@Inject will only works in CDI managed instances

This only works at least Java EE 7 and CDI 1.1 server:

@FacesConverter
public class MyConverter implements Converter {

  protected MyService myService;    

  @Override
  public Object getAsObject(FacesContext context, UIComponent component, String value) {
      myService = CDI.current().select(MyService .class).get();
      myService.doSomething();
  }

}
