我们用sleep模拟100W个1秒的IO操作,看看虚拟线程和平台线程的性能对比。 public static void main(String[] args) throws InterruptedException { // 使用虚拟线程池 ExecutorService virtualThreadExecutor = Executors.newVirtualThreadPerTaskExecutor(); executor(virtualThreadExecutor, "虚拟线程池"); // 创建一个固定...
Runnable runnable = -> System.out.println(Thread.sleep(10)); Thread thread = Thread.startVirtualThread(runnable); //等待虚拟线程结束 thread.join; Executors.newVirtualThreadPerTaskExecutor 创建一个 ExecutorService,该 ExecutorService 为每个任务创建一个新的虚拟线程: try(varexecutor = Executors.newVirtual...
看一下虚拟线程 try(ExecutorServiceexecutor=Executors.newVirtualThreadPerTaskExecutor()){for(inti=0;i<=600;i++){StringtaskName="Task"+i;executor.execute(()->callService(taskName));}} 这里创建了一个虚拟线程工厂(而不是线程池,记住不要使用虚拟化的线程池),它会给每个任务创建新的虚拟线程。 程序...

虚拟线程(Virtual Thread)是 Java 19 引入的一种轻量级线程,它在很多其他语言中被称为协程、纤程、绿色线程、用户态线程等。在 Java 21 中,虚拟线程成为正式功能 1. 虚拟线程和平台线程 平台线程:传统 Java 线程是和操作系统线程 1:1 映射的,平台线程由操作系统负责调度。平台线程是一种重量级资源,受限于创建销毁...

首先,使用Executors.newVirtualThreadPerTaskExecutor()创建一个虚拟线程的执行器。 然后,提交一个延迟任务,使用Thread.sleep(3000)模拟延迟。 接下来,通过for循环提交多个延时任务,任务内部再次使用Thread.sleep(2000)来模拟延迟执行。 最后,通过调用executor.shutdown()来关闭执行器,防止资源泄露。
