public @interface RequestScoped
Specifies that a bean is request scoped.
While RequestScoped must be associated with the built-in request 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 request context.
The request scope is active:
- during the
service()method of any servlet in the web application, during thedoFilter()method of any servlet filter and when the container calls anyServletRequestListenerorAsyncListener, - during any Java EE web service invocation,
- during any remote method invocation of any EJB, during any asynchronous method invocation of any EJB, during any call to an EJB timeout method and during message delivery to any EJB message-driven bean, and
- during
@PostConstructcallback of any bean.
The request context is destroyed:
- at the end of the servlet request, after the
service()method, alldoFilter()methods, and allrequestDestroyed()andonComplete()notifications return, - after the web service invocation completes,
- after the EJB remote method invocation, asynchronous method invocation, timeout or message delivery completes if it did not already exist when the invocation occurred, or
- after the
@PostConstructcallback completes, if it did not already exist when the@PostConstructcallback occurred.
An event with qualifier @Initialized(RequestScoped.class) is fired when the request context is initialized and
an event with qualifier @Destroyed(RequestScoped.class) when the request context is destroyed. The event payload
is:
- the
ServletRequestif the context is initialized or destroyed due to a servlet request, or - the
ServletRequestif the context is initialized or destroyed due to a web service invocation, or - any
java.lang.Objectfor other types of request.
