IdGenerator ID生成器
---

使用spring data redis生成自增ID。使用方式如下：

```java
@RunWith(SpringJUnit4ClassRunner.class)
@SpringBootTest
public class ApplicationTest {

    @Autowired
    OrderIdGenerator orderIdGenerator;

    @Autowired
    UserIdGenerator userIdGenerator;

    @Test
    public void testName1() throws Exception {
        for (int i = 0; i < 333; i++) {
            long id = userIdGenerator.next();
            System.out.println(id);
        }
    }

    @Test
    public void testName2() throws Exception {
        ExecutorService executorService = Executors.newCachedThreadPool();
        final Semaphore semaphore = new Semaphore(500);
        final CountDownLatch countDownLatch = new CountDownLatch(10000);
        for (int i = 0; i < 10000; i++) {
            executorService.execute(new Runnable() {
                @Override
                public void run() {
                    try {
                        semaphore.acquire();
                        generate();
                        semaphore.release();
                    } catch (InterruptedException e) {
                        e.printStackTrace();
                    }
                    countDownLatch.countDown();
                }
            });
        }
        countDownLatch.await();
        executorService.shutdown();
    }

    private void generate() {
        long id = orderIdGenerator.nextResetDay();
        System.out.println(id);
    }
}
```
