我可以停止Play框架承诺吗？

Question

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?

Answer 1

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.

Answer 2

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。
