RequestContextListener (Spring Framework 5.2.12.RELEASE API)

java.lang.Object
- org.springframework.web.context.request.RequestContextListener

所有已实现的接口:
EventListener, ServletRequestListener
```
public class RequestContextListener
extends 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.
