java 多线程提交任务模板

介绍

  java 中多线程批量处理任务的代码模板。

代码

import java.util.concurrent.ArrayBlockingQueue;
import java.util.concurrent.ThreadPoolExecutor;
import java.util.concurrent.TimeUnit;

/**
 * 多线程提交任务
 */
public class ThreadPoolExecutorDemo {

    public static void main(String[] args) {

        int threadCount = 0;

        ThreadPoolExecutor executor = new ThreadPoolExecutor(threadCount <= 50 ? threadCount : 50, 50, 0L,
                TimeUnit.MILLISECONDS, new ArrayBlockingQueue<Runnable>(2000));

        try {
            String param = "";
            ExecutorTask urlTask = new ExecutorTask(param);
            executor.execute(urlTask);
        } catch (Exception e) {

        } finally {
            executor.shutdown();
        }

    }

}

class ExecutorTask implements Runnable {

    private String param;

    public ExecutorTask(String param) {
        this.param = param;
    }

    @Override
    public void run() {
        System.out.println(param);
    }

}
