With pure cdi api,in every module we have to create the same annotation literal classes. For example: In module A,we have an observes method: public void hundleCommand(@Observes @Named("shell") MyCommand command){...} In module B and C,we should send event to module A: @Inject Event<MyCommand> event; @Override public void execute() throws Exception { event.select(new NamedLiteral("shell")).fire(new MyCommand()); } In order to send event,we must define a literal type: public class NamedLiteral extends AnnotationLiteral<Named> implements Named { private static final long serialVersionUID = -1457223276475846060L; private final String value; public NamedLiteral(String value) { this.value = value; } public NamedLiteral() { value = ""; } @Override public String value() { return value; } } Why cdi do not define a util class to simplify those as following: @Inject Event<MyCommand> event; @Override public void execute() throws Exception { Map<String, String> values=new HashMap<String, String>(); values.put("value", "shell"); Named commandQualifier = AnnotationInstanceProvider.of(Named.class, values); event.select(commandQualifier).fire(new MyCommand()); }
