I m 采用Executorservice处理多个校对的任务要求并使用 未来从<代码>Executorservice#submit()退回,以跟踪任务的进展情况。
如果提出请求者在一段时间后仍未得到处理,我想取消请求,并向他们提供反馈。
因此,我要知道,如果任务要求等待完成,或者我取消,并向请求者提供反馈,那么是否正在处理。
欢迎任何帮助和帮助。 感谢!
回答太晚,但你为什么没有界定你的任务,以某种不稳定的“标准”旗帜? 然后,你就可以在你的捕获条款中质疑国旗。
如果您使用<代码>Future.cancel(false),那么如果任务已经启动,就可以完成。 即使你使用<代码>cancel(true),也可通过任何途径使用,除非交谈能够进行可中断的操作,或检查被打的国旗。
我怀疑你没有必要知道这项任务是否已经启动。 即使你有这种方法,在你检查时,这项任务可能不会开始,而是在你试图取消时开始。
