Class AsyncSupportConfigurer

Constructor Detail

• AsyncSupportConfigurer

  public AsyncSupportConfigurer()

Method Detail

• setTaskExecutor

  public AsyncSupportConfigurer setTaskExecutor​(AsyncTaskExecutor taskExecutor)

  Set the default AsyncTaskExecutor to use when a controller method returns a Callable. Controller methods can override this default on a per-request basis by returning a WebAsyncTask.

  By default a SimpleAsyncTaskExecutor instance is used, and it's highly recommended to change that default in production since the simple executor does not re-use threads.

  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, e.g. 10 seconds on Tomcat with Servlet 3.

  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
