是不是可以为ForkJoinPool提供线程库或名称模式？ [英] Is it not possible to supply a thread facory or name pattern to ForkJoinPool?

问题描述

我想为工作窃取池使用的ForkJoinPool的线程设置名称，由

I would like to set name for threads of the ForkJoinPool used by work stealing pool, supplied by

ExecutorService newWorkStealingPool(int parallelism)

或

ExecutorService newWorkStealingPool()

到目前为止，我找不到设置自定义的方法这个 ExecutorService 使用的线程上的名称有没有办法？

So far I could not find a way to set custom names on threads used by this ExecutorService, is there a way?

newWorkStealingPool（） 基本上提供 ForkJoinPool ，但 ForkJoinPool 也没有提供的公共构造函数名称模式。

newWorkStealingPool() basically supplies a ForkJoinPool, but ForkJoinPool also doesn't have a public constructor with supplied name pattern.

更新：
我现在发现
的构造函数 ForkJoinPool 需要一个线程工厂 ForkJoinPool.ForkJoinWorkerThreadFactory 。但是工厂应该返回 ForkJoinWorkerThread ，它没有公共构造函数。所以我想我必须继承 ForkJoinWorkerThread 。

update: I have now found this constructor of ForkJoinPool which takes a thread factory ForkJoinPool.ForkJoinWorkerThreadFactory. But factory should return a ForkJoinWorkerThread, which doesn't have a public constructor. So I guess I will have to subclass ForkJoinWorkerThread.

推荐答案

这似乎作为最低要求的代码，重用现有的默认工厂：

This seems to be the minimum required code, reusing the existing default factory:

final ForkJoinWorkerThreadFactory factory = new ForkJoinWorkerThreadFactory()
{
    @Override           
    public ForkJoinWorkerThread newThread(ForkJoinPool pool)
    {
        final ForkJoinWorkerThread worker = ForkJoinPool.defaultForkJoinWorkerThreadFactory.newThread(pool);
        worker.setName("my-thread-prefix-name-" + worker.getPoolIndex());
        return worker;
    }
};

forkJoinPool = new ForkJoinPool(Runtime.getRuntime().availableProcessors(), factory, null, false);
