Annotation Interface RequestScoped

@Target({TYPE,METHOD,FIELD}) @Retention(RUNTIME) @Documented @NormalScope @Inherited 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 the doFilter() method of any servlet filter and when the container calls any ServletRequestListener or AsyncListener,
  • 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 @PostConstruct callback of any bean.

The request context is destroyed:

  • at the end of the servlet request, after the service() method, all doFilter() methods, and all requestDestroyed() and onComplete() 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 @PostConstruct callback completes, if it did not already exist when the @PostConstruct callback 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 ServletRequest if the context is initialized or destroyed due to a servlet request, or
  • the ServletRequest if the context is initialized or destroyed due to a web service invocation, or
  • any java.lang.Object for other types of request.
