org.springframework.web.context.request.AsyncWebRequestInterceptor

Extends {@code WebRequestInterceptor} with a callback method invoked duringasynchronous request handling.

When a handler starts asynchronous request handling, the DispatcherServlet exits without invoking {@code postHandle} and {@code afterCompletion}, as it normally does, since the results of request handling (e.g. ModelAndView) are not available in the current thread and handling is not yet complete. In such scenarios, the {@link #afterConcurrentHandlingStarted(WebRequest)}method is invoked instead allowing implementations to perform tasks such as cleaning up thread bound attributes.

When asynchronous handling completes, the request is dispatched to the container for further processing. At this stage the DispatcherServlet invokes {@code preHandle}, {@code postHandle} and {@code afterCompletion} as usual. @author Rossen Stoyanchev @since 3.2 @see org.springframework.web.context.request.async.WebAsyncManager

    this.requestInterceptor.afterCompletion(new DispatcherServletWebRequest(request, response), ex);
  }


  public void afterConcurrentHandlingStarted(HttpServletRequest request, HttpServletResponse response, Object handler) {
    if (this.requestInterceptor instanceof AsyncWebRequestInterceptor) {
      AsyncWebRequestInterceptor asyncInterceptor = (AsyncWebRequestInterceptor) this.requestInterceptor;
      DispatcherServletWebRequest webRequest = new DispatcherServletWebRequest(request, response);
      asyncInterceptor.afterConcurrentHandlingStarted(webRequest);
    }
  }
