线程工具类

public class ExecutorServiceUtil {
	// 设置线程名称，其他方式有CustomizableThreadFactory、BasicThreadFactory
    public static ThreadFactory namedThreadFactory = new ThreadFactoryBuilder()
            .setNameFormat("ExecutorUtil-pool-%d").build();
	// 使用ThreadPoolExecutor创建线程池
	// Runtime.getRuntime().availableProcessors() 获取可用的计算资源
	// 400:最大线程池大小;0L:线程最大空闲时间;TimeUnit.MILLISECONDS:时间单位;new LinkedBlockingQueue<Runnable>(1024):线程等待队列;namedThreadFactory:线程创建工厂;new ThreadPoolExecutor:拒绝策略,AbortPolicy()默认策略
    private static final ExecutorService executorService = new ThreadPoolExecutor(
            2*Runtime.getRuntime().availableProcessors(),
            400, 0L, TimeUnit.MILLISECONDS,
        new LinkedBlockingQueue<Runnable>(1024), namedThreadFactory, new ThreadPoolExecutor.AbortPolicy());


    public static void execute (Runnable runnable){
        executorService.execute(runnable);
    }

    public static void callable(FutureTask futureTask){
        executorService.submit(futureTask);
    }
}

使用：

try {
	ExecutorServiceUtil.execute(() -> {
		// 开辟线程执行代码
	}
}catch(Exception e){
	log.error("--------");
}
