多线程并发测试，用了都说好

@Test
    public void testMultiThread() throws InterruptedException {
        CountDownLatch countDownLatch = new CountDownLatch(10);
        ExecutorService executorService = Executors.newFixedThreadPool(10);
        CyclicBarrier cyclicBarrier = new CyclicBarrier(10);
        for (int i = 0; i < 10; i++) {
            executorService.execute(new Runnable() {
                @Override
                public void run() {
                    try {
                        Thread.sleep(new Random().nextInt(60)*1000);
                        cyclicBarrier.await();
                        // 业务方法
                        tagContentServiceTask.taskContentAlreadyQueue();
                        log.info("开始执行 {},{}",Thread.currentThread().getName());
                        countDownLatch.countDown();
                    } catch (InterruptedException e) {
                        e.printStackTrace();
                    } catch (BrokenBarrierException e) {
                        e.printStackTrace();
                    }
                }
            });
        }
        countDownLatch.await();
        executorService.shutdown();
    }
