    • setTaskExecutor

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

      If your application has controllers with such return types, please configure an AsyncTaskExecutor as the one used by default is not suitable for production under load.

      Parameters:
      taskExecutor - the task executor instance to use by default

    • 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.

      Parameters:
      timeout - the timeout value in milliseconds

    • registerCallableInterceptors

      public AsyncSupportConfigurer registerCallableInterceptors(CallableProcessingInterceptor... interceptors)
      Configure lifecycle interceptors with callbacks around concurrent request execution that starts when a controller returns a Callable.
      Parameters:
      interceptors - the interceptors to register

    • registerDeferredResultInterceptors

      public AsyncSupportConfigurer registerDeferredResultInterceptors(DeferredResultProcessingInterceptor... interceptors)
      Configure lifecycle interceptors with callbacks around concurrent request execution that starts when a controller returns a DeferredResult.
      Parameters:
      interceptors - the interceptors to register
