public static void main(String[] args) {
    System.out.println("main....start.....");
    CompletableFuture<Void> future = CompletableFuture.runAsync(() -> {
        System.out.println("当前线程：" + Thread.currentThread().getId());
        int i = 10 / 2;
        System.out.println("运行结果：" + i);
    }, executor);
    System.out.println("main....end.....");
}
