@Target(value={TYPE,METHOD,FIELD}) @Retention(value=RUNTIME) @Documented @NormalScope @Inherited public @interface ApplicationScoped
Specifies that a bean is application scoped.
While ApplicationScoped
must be associated with the built-in application context required by the specification,
third-party extensions are
allowed to also associate it with their own context. Behavior described below is only related to the built-in application context.
The application scope is active:
service()
method of any servlet in the web application, during the doFilter()
method of any
servlet filter and when the container calls any ServletContextListener
, HttpSessionListener
,
AsyncListener
or ServletRequestListener
,@PreDestroy
callback of any bean with any normal scope other than
@ApplicationScoped
is called, and@PostConstruct
callback of any bean.The application context is shared between all servlet requests, web service invocations, EJB remote method invocations, EJB asynchronous method invocations, EJB timeouts and message deliveries to message-driven beans that execute within the same application.
The application context is destroyed when the application is shut down.
An event with qualifier @Initialized(ApplicationScoped.class)
is fired when the application context is initialized
and an event with qualifier @Destroyed(ApplicationScoped.class)
when the application context is destroyed.
The event payload is:
ServletContext
if the application is a web application deployed to a Servlet container, orjava.lang.Object
for other types of application.
