Java线程池创建

💖简介

Java 手动创建线程池

📖代码

package com.zk.app.utils;import com.google.common.util.concurrent.ThreadFactoryBuilder;import java.util.concurrent.ArrayBlockingQueue;
import java.util.concurrent.ExecutorService;
import java.util.concurrent.ThreadPoolExecutor;/*** @program: ZK* @description:* @author: zuokun* @create: 2024-11-20 15:44**/
public class ThreadPoolUtils {private static volatile ExecutorService testExecutor;public static ExecutorService getTestExecutor() {if(testExecutor == null){synchronized (ThreadPoolUtils.class){if(testExecutor == null){testExecutor = new ThreadPoolExecutor(10, 20, 10,java.util.concurrent.TimeUnit.SECONDS,new ArrayBlockingQueue<>(100),new ThreadFactoryBuilder().setNameFormat("test-pool-%d").build(),new ThreadPoolExecutor.CallerRunsPolicy());}}}return testExecutor;}}

ThreadFactoryBuilder().setNameFormat 是 Guava 库中的一个方法，用于构建 ThreadFactory 实例。这个 ThreadFactory 可以用来创建新的线程，并且可以设置线程的名称格式。

⭐使用

    @Testpublic void poolTest() {for (int i = 0; i < 10; i++) {ThreadPoolUtils.getTestExecutor().submit(() -> {System.out.println(Thread.currentThread().getName());});}}

🌟结果

test-pool-0
test-pool-3
test-pool-2
test-pool-1
test-pool-4
test-pool-5
test-pool-6
test-pool-7
test-pool-8
test-pool-9
