CompletableFuture线程并行与CountDownLatch(闭锁)

        ExecutorService executors =Executors.newFixedThreadPool(5);
		
		
		CompletableFuture aFuture = CompletableFuture.supplyAsync(() -> {
			log.info("aaaaaaaaaaaaaaaaaa");
			return "aa";
		}, executors);
		
		CompletableFuture bFuture = CompletableFuture.supplyAsync(() -> {
			log.info("bbbbbbbbbbbbbbbbb");
			return "bb";
		}, executors);
		
		CompletableFuture cFuture = CompletableFuture.supplyAsync(() -> {
			log.info("cccccccccc");
			return "cc";
		}, executors);
		
		log.info("return:"+aFuture.get());
		log.info("return:"+bFuture.get());
		log.info("return:"+cFuture.get());
