Default


javax.enterprise.inject
Annotation Type Default

@Target(value={TYPE,METHOD,PARAMETER,FIELD})
@Retention(value=RUNTIME)
@Documented
@Qualifier
public @interface Default

The default qualifier type.

If a bean does not explicitly declare a qualifier other than @Named, the bean has the qualifier @Default.

If an injection point declares no qualifier, the injection point has exactly one qualifier, the default qualifier @Default.

The following are equivalent:

 @ConversationScoped
 public class Order {
 
    private Product product;
    private User customer;
 
    @Inject
    public void init(@Selected Product product, User customer) {
       this.product = product;
       this.customer = customer;
   }

 }
 
 @Default @ConversationScoped
 public class Order {
   
    private Product product;
    private User customer;
   
    @Inject
    public void init(@Selected Product product, @Default User customer) {
       this.product = product;
       this.customer = customer;
    }
 
 }
