@Async默认异步配置使用的是SimpleAsyncTaskExecutor,该线程池默认来一个任务创建一个线程,若系统中不断的创建线程,最终会导致系统占用内存过高,引发OutOfMemoryError错误。针对线程创建问题,SimpleAsyncTaskExecutor提供了限流机制,通过concurrencyLimit属性来控制开关...

Because .Timeout work from external of task, can not stop timeoutted task. .Timeout means ignore result when timeout. If you pass a CancellationToken to the method, it will act from inside of the task, so it is possible to stop a running task....
In conventional Node.js code, asynchronous functions take a callback as their last parameter and don't return any value. Therefore, calls to these functions arenot awaitable. However, awaitable versions may be obtained with relative ease using something likebluebird'spromisifyAll(), orthunkify. ...
