Class RequestContextListener

java.lang.Object

org.springframework.web.context.request.RequestContextListener

All Implemented Interfaces:

java.util.EventListener, ServletRequestListener

public class RequestContextListener
extends java.lang.Object
implements ServletRequestListener

Servlet listener that exposes the request to the current thread, through both LocaleContextHolder and RequestContextHolder. To be registered as listener in web.xml.

Alternatively, Spring's RequestContextFilter and Spring's DispatcherServlet also expose the same request context to the current thread. In contrast to this listener, advanced options are available there (e.g. "threadContextInheritable").

This listener is mainly for use with third-party servlets, e.g. the JSF FacesServlet. Within Spring's own web support, DispatcherServlet's processing is perfectly sufficient.
