org.springframework.web.context.request.async.WebAsyncManager
The central class for managing asynchronous request processing, mainly intended as an SPI and not typically used directly by application classes.
An async scenario starts with request processing as usual in a thread (T1). Concurrent request handling can be innitiated by calling {@linkplain #startCallableProcessing(Callable,Object) startCallableProcessing} or{@linkplain #startDeferredResultProcessing(DeferredResult,Object) startDeferredResultProcessing}both of which produce a result in a separate thread (T2). The result is saved and the request dispatched to the container, to resume processing with the saved result in a third thread (T3). Within the dispatched thread (T3), the saved result can be accessed via {@link #getConcurrentResult()} or its presencedetected via {@link #hasConcurrentResult()}. @author Rossen Stoyanchev @since 3.2 @see org.springframework.web.context.request.AsyncWebRequestInterceptor @see org.springframework.web.servlet.AsyncHandlerInterceptor @see org.springframework.web.filter.OncePerRequestFilter#shouldNotFilterAsyncDispatch @see org.springframework.web.filter.OncePerRequestFilter#isAsyncDispatch
