      • setTaskExecutor

        public AsyncSupportConfigurer setTaskExecutor(AsyncTaskExecutor taskExecutor)
        The provided task executor is used to:
        1. Handle Callable controller method return values.
        2. Perform blocking writes when streaming to the response through a reactive (e.g. Reactor, RxJava) controller method return value.

        By default only a SimpleAsyncTaskExecutor is used. However when using the above two use cases, it's recommended to configure an executor backed by a thread pool such as ThreadPoolTaskExecutor.

      • setDefaultTimeout

        public AsyncSupportConfigurer setDefaultTimeout(long timeout)
        Specify the amount of time, in milliseconds, before asynchronous request handling times out. In Servlet 3, the timeout begins after the main request processing thread has exited and ends when the request is dispatched again for further processing of the concurrently produced result.

        If this value is not set, the default timeout of the underlying implementation is used, e.g. 10 seconds on Tomcat with Servlet 3.

      • registerCallableInterceptors

        public AsyncSupportConfigurer registerCallableInterceptors(CallableProcessingInterceptor... interceptors)
        Configure lifecycle interceptors with callbacks around concurrent request execution that starts when a controller returns a Callable.
