public @interface RequestScoped

Specifies that a bean is request scoped.

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 asynchronous observer method notification,
  • 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 any message delivery to a MessageListener for a JMS topic or queue obtained from the Java EE component environment.

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 asynchronous observer notification completes,
  • after the EJB remote method invocation, asynchronous method invocation, timeout or message delivery completes, or
  • after the message delivery to the MessageListener completes.
