Examples with ConcurrentHashSet cn.hutool.core.collection.ConcurrentHashSet used on opensource projects

Example 1 with ConcurrentHashSet

use of cn.hutool.core.collection.ConcurrentHashSet in project hutool by looly.

the class IdUtilTest method snowflakeBenchTest2.

@Test
@Ignore
public void snowflakeBenchTest2() {
    final Set<Long> set = new ConcurrentHashSet<>();
    // 线程数
    int threadCount = 100;
    // 每个线程生成的ID数
    final int idCountPerThread = 10000;
    final CountDownLatch latch = new CountDownLatch(threadCount);
    for (int i = 0; i < threadCount; i++) {
        ThreadUtil.execute(() -> {
            for (int i1 = 0; i1 < idCountPerThread; i1++) {
                long id = IdUtil.getSnowflake(1, 1).nextId();
                set.add(id);
            // Console.log("Add new id: {}", id);
            }
            latch.countDown();
        });
    }
    // 等待全部线程结束
    try {
        latch.await();
    } catch (InterruptedException e) {
        throw new UtilException(e);
    }
    Assert.assertEquals(threadCount * idCountPerThread, set.size());
}
