threadpoolexecutor 设置线程名称

在使用 ThreadPoolExecutor 时，您可以通过实现 ThreadFactory 接口来设置线程的名称。ThreadFactory 是一个工厂接口，它的作用是创建线程，您可以通过重写它的 newThread 方法来设置线程的名称。

代码示例如下：

import java.util.concurrent.ThreadFactory;
public class NamedThreadFactory implements ThreadFactory {
    private final String name;
    public NamedThreadFactory(String name) {
        this.name = name;
    @Override
    public Thread newThread(Runnable r) {
        Thread t = new Thread(r);
        t.setName(name);
        return t;
ThreadPoolExecutor executor = new ThreadPoolExecutor(
        numThreads,   // core pool size
        numThreads,   // maximum pool size
        0L,           // keep-alive time for idle threads
        TimeUnit.MILLISECONDS,
        new LinkedBlockingQueue<Runnable>(),
        new NamedThreadFactory("MyThread"));
这样，您就可以在线程池中创建具有指定名称的线程了。
