多线程的使用

1.线程池的创建：

在定义完线程池后，进行业务代码的处理：

public class ThreadPoolUtil {
    /**
     * 线程工厂定义
     */
    private static ThreadFactory threadFactory = new ThreadFactoryBuilder().setNameFormat("thread-pool-%d").build();

    /**
     * 线程池定义
     */
    public static ThreadPoolExecutor executor =
            new ThreadPoolExecutor(
                    5,
                    6,
                    10,
                    TimeUnit.SECONDS,
                    new LinkedBlockingQueue<>(10000),
                    threadFactory);
    /**
     * 异步执行
     *
     * @param runnable
     */
    public static void execute(Runnable runnable) {
        executor.execute(runnable);
    }
}

2.业务代码的处理 :

        List<CompletableFuture<Void>> completableFutures = new ArrayList<>();

        completableFutures.add(CompletableFuture.runAsync(() ->{
            //填充业务代码

        }, ThreadPoolUtil.executor));

        completableFutures.add(CompletableFuture.runAsync(() ->{
            //填充业务代码
        }, ThreadPoolUtil.executor));

        CompletableFuture.allOf(completableFutures.toArray(new CompletableFuture[0])).join();
