在Scala中，是否有办法告诉您正在哪个执行上下文中运行？ [英] In Scala, is there a way to tell which execution context you are running in?

问题描述

在Scala中，如果我知道一段代码正在Future中运行，是否有办法找出Future驻留在哪个ExecutionContext中？例如，以便我可以将此信息写到日志中。

In Scala, if I know that a piece of code is running in a Future, is there a way of finding out in which ExecutionContext the Future resides? E.g., so that I can write out this information to a log.

别担心，我不想做任何邪恶的事情。我只想要调试信息。

Don't worry, I don't want to do anything nefarious. I just want the information for debugging.

推荐答案

维克多·巴生（Viktor Klang）在评论中说：

Viktor Klang had this to say in a comment:

任何明智的ExecutionContext应该适当地命名其线程，
然后使用Thread.currentThread（）。getName（）在日志中显示。

Any sensible ExecutionContext ought to name its threads appropriately, then it shows up in logs using Thread.currentThread().getName().

我认为这正是我所需要的。

I think that this is just what I need.

谢谢，维克多！
