Akka Scheduler,时间单位错误

Question

我正在尝试向演员发送推迟的消息.因此,我使用了http://doc.akka.io/docs/akka/2.1.0/scala/scheduler.html中Scheduler的代码示例.

[error] /home/zeus/terra/src/main/scala/hw.scala:55: value milliseconds is not a member of Int
[error]         50 milliseconds,
[error]            ^
[error] one error found
[error] (compile:compile) Compilation failed
[error] Total time: 3 s, completed Aug 11, 2014 4:07:48 PM

令人惊讶的是,发生了这个错误... milliseconds从我的代码中删除了另一个错误:

[error] /home/vador/death_star/src/main/scala/hw.scala:55: type mismatch;
[error]  found   : Int(50)
[error]  required: scala.concurrent.duration.FiniteDuration
[error]         50,
[error]         ^
[error] one error found
[error] (compile:compile) Compilation failed
[error] Total time: 3 s, completed Aug 11, 2014 4:12:32 PM

我不明白这一点.

Answer 1

根据评论,@ Ende Neu可能走在正确的轨道上.

import scala.concurrent._

这不会给你持续时间暗示.你还需要导入那些:

import scala.concurrent.duration._

您想要的实际含义是打开的 scala.concurrent.duration.DurationInt
