使用ThreadFactoryBuilder创建线程池

使用 ThreadFactoryBuilder

使用guava的ThreadFactoryBuilder来创建线程池

栈不会溢出，合理化资源

package com.macro.mall.test.thread;

import com.google.common.util.concurrent.ThreadFactoryBuilder;
import org.apache.tomcat.util.threads.ThreadPoolExecutor;

import java.util.concurrent.ExecutorService;
import java.util.concurrent.LinkedBlockingQueue;
import java.util.concurrent.ThreadFactory;
import java.util.concurrent.TimeUnit;

public class ExecutorsDemo {
    
    

    private static ThreadFactory namedThreadFactory = new ThreadFactoryBuilder()
            .setNameFormat("demo-pool-%d").build();

    private static ExecutorService pool = new ThreadPoolExecutor(5, 100,
            0L, TimeUnit.MILLISECONDS,
            new LinkedBlockingQueue<Runnable>(1024), namedThreadFactory, new ThreadPoolExecutor.AbortPolicy());

    public static void main(String[] args) {
    
    

        for (int i = 0; i < Integer.MAX_VALUE; i++) {
    
    
            pool.execute(new SubThread());
        }
        System.out.println("qqq");

    }


    private static class SubThread implements Runnable {
    
    

        @Override
        public void run() {
    
    
            System.out.println(Thread.currentThread().getState()+"----------"+Thread.currentThread().getName());
        }
    }
}

核心线程数五个

Integer.MAX_VALUE 没有溢出。
