Jakarta EE @Named Anotasyonu

Giriş

Açıklaması şöyle

It is a special qualifier with a String value attribute. When used at an injection point, only beans with a matching @Named qualifier are considered:

Örnek

Şöyle yaparız

@Named("feline")
class Cat implements Pet { }

@Inject
@Named("feline")
Pet felinePet;

Örnek

Açıklaması şöyle

@Named is special in that it does not replace the implicit @Default qualifier. Hence, the following definition-injection pair is a match (given that there is no other Pet candidate):

Şöyle yaparız

// bean definition with @Named,
// retains the implicit @Default qualifier:

@Named("feline")
class Cat implements Pet { }

// injection point with implicit @Default qualifier:

@Inject
Pet felinePet;
