Is there an advisable way to stop a Play Framework promise? For instance,
import play.api.libs.concurrent.Promise
val timeoutFuture = Promise.timeout({
Logger.info("timeout expired.")
}, myTimeoutValue)
What would be a good way to cancel this future before myTimeoutValue
expires?
If the timeout period is too long just reduce the myTimeoutValue
. If you wish to interrupt the execution the is a way shown here by completing a future.
This is however questionable way to do things since you can just ignore the result of your Promise/Future if it takes too long, but since you'll have to set a period for when its too long then its just as well as putting that as the timeout value.
最后,恐怕答案是否定的-无法在超时到期之前取消此类承诺。
