java - Existing ForkJoinPool or ExecutorService?

Question

I have a silly problem, I need an ExecutorService (and ForkJoinPool is such a thing) but I don't really want to initialise a new one and keep that reference, I remember a while back running into a JDK class that maintained an static ForkJoinPool for various uses and that could be used by other processes, but I can't seem to find it and there is not that much info about such a thing online. Does any know if such a thing exists ?

Answer 1

ForkJoinPool.commonPool()是单个静态实例

您可以使用Executors.newWorkStealingPool来获取工作窃取池（ForkJoinPool.defaultForkJoinWorkerThreadFactory在后台使用），但这需要您存储池引用。

因此，这两个都将是每个 JVM（每个进程），而不是您所说的跨进程，我不知道您可以使用哪个池来做到这一点。
