CDI Stereotypes

Stereotype

• annotations

• incorporates other annotations

• specifies

  • a default scope

  • zero or more interceptor bindings

  • optionally a @Named annotation, guaranteeing default EL naming

  • optionally an @Alternative annotation, specifying all beans in this stereotype are alternatives

Example stereotype:

@RequestScoped // the default scope

@Secure // interceptor binding

@Transactional // interceptor binding

@Named // guarantee EL naming

@Stereotype

@Target(TYPE)

@Retention(RUNTIME)

public @interface Action {}

@Alternative

@Stereotype

@Target(TYPE)

@Retention(RUNTIME)

public @interface Mock {}

Applying Stereotype

• possible to apply multiple stereotypes to the same bean

• can override scope by specifying a different scope for the bean
