JarCastingsnowflake-plus 
This is an id generator which use the snowflake algorithm. It's developed by spring-boot. This component works without configuring work-id. The idea of this component came from Meituan tech who designed the snowflake id with zookeeper.
Work Type
There are three types for the component.
- local: The work-id will be got from your local application's properties file.
- zookeeper: The work-id will be registered to your zookeeper server.
- ip: The work-id will be got by the last part of your local server's IP. For example: If your IP is 192.168.1.200, the work-id is 200.
Quick Start
- add maven dependency
<dependency>
<groupId>org.onevroad</groupId>
<artifactId>snowflake-plus-core</artifactId>
<version>0.3.0</version>
</dependency>
- add zookeeper's dependency(if your work-type is zookeeper)
<dependency>
<groupId>org.apache.curator</groupId>
<artifactId>curator-recipes</artifactId>
<version>4.2.0</version>
</dependency>
- add config
snowflake:
plus:
#local，zookeeper，ip. Default is local.
work-type: zookeeper
#initial start time, default: 2019-08-01 00:00:00 (UTC)
start-time: 1564617600000
#the number of bit for worker id, default: 8bit
worker-id-bits: 8
#the number of bit for sequence, default: 12bit
sequence-bits: 12
#If your work-type is local, you need configure the work-id
worker-id: 1
#If your work-type is zookeeper, you need configure the following parameters
#application's registered name
name: snowflake-plus-sample
#application's registered port
port: 8001
#the zookeeper address
zk-address: localhost:2181
- get ID
@RestController
public class SnowflakeIdController {
@Autowired
private SnowflakeService snowflakeService;
@GetMapping("/snowflake/id/get")
public long getId() {
return snowflakeService.getId();
}
}
