barrier

public static void main(String[] args) throws InterruptedException, BrokenBarrierException { ExecutorService executorService = Executors.newFixedThreadPool(10); RestTemplate restTemplate = new RestTemplate(); String url = "URL"; String data = ""; CyclicBarrier cyclicBarrier = new CyclicBarrier(11); AtomicInteger counter = new AtomicInteger(0); for (int i = 0; i { int idx = counter.addAndGet(1); cyclicBarrier.await(); ResponseEntity result = restTemplate.postForEntity(url, data, String.class); System.out.println(result + " " + idx); return null; }); } cyclicBarrier.await(); }

예전에 동시성 할 때 이건 잘 이해가 안됐는데 이건 팍팍된당
