Java异步

一、解决 CompletableFuture.runAsync 异步线程不执行的问题

方式一：指定线程池

private static final ExecutorService cachedThreadPool = Executors.newCachedThreadPool();

    public static void main(String[] args) throws InterruptedException, ExecutionException {
         CompletableFuture.runAsync(() ->{
            try {
                method();
            } catch (InterruptedException e) {
                throw new RuntimeException(e);
            }
        },cachedThreadPool);
        System.out.println("main +++++++++++++++++++++++");
    }

    private static void method() throws InterruptedException {
        System.out.println("start==================");
        Thread.sleep(10000);
        System.out.println("end====================");
    }
