java--ThreadPool线程池简单用法

package com.threadPool;



import java.util.concurrent.ArrayBlockingQueue;

import java.util.concurrent.ThreadPoolExecutor;

import java.util.concurrent.TimeUnit;



public class TestThreadPool {

	private static int produceTaskSleepTime = 0;



	private static int produceTaskMaxNumber = 100000;



	public static void main(String[] args) {



		// 构造一个线程池

		ThreadPoolExecutor threadPool = new ThreadPoolExecutor(6, 100, 3,

				TimeUnit.SECONDS, new ArrayBlockingQueue<Runnable>(3),

				new ThreadPoolExecutor.DiscardOldestPolicy());



		for (int i = 1; i <= produceTaskMaxNumber; i++) {

			try {

				String task = "task@ " + i;

				System.out.println("创建任务并提交到线程池中：" + task);

				threadPool.execute(new ThreadPoolTask(task));



				Thread.sleep(produceTaskSleepTime);

			} catch (Exception e) {

				e.printStackTrace();

			}

		}

	}

}

 

 

package com.threadPool;



import java.io.Serializable;



public class ThreadPoolTask implements Runnable, Serializable {

	private Object attachData;



	ThreadPoolTask(Object tasks) {

		this.attachData = tasks;

	}



	public void run() {



		System.out.println("开始执行任务：" + attachData);



		attachData = null;

	}



	public Object getTask() {

		return this.attachData;

	}

}

 

 

输出结果：

开始执行任务：task@ 97856

开始执行任务：task@ 97857

创建任务并提交到线程池中：task@ 97858

创建任务并提交到线程池中：task@ 97859

开始执行任务：task@ 97858

开始执行任务：task@ 97859

创建任务并提交到线程池中：task@ 97860
