# Id
[](https://travis-ci.com/Bpazy/Id)
[](https://codecov.io/gh/Bpazy/Id)
分布式id生成，整体随时间递增。
最大支持1024个节点，每个节点每毫秒生成ID上限为4096个。
## Usage
Add maven denpendency:
```xml
com.github.bpazy
id
{version}
```
And then go:
```java
public class Main {
public static void main(String[] args) {
System.out.println(Id.next());
}
}
```
