SequenceIdWorker

public SequenceIdWorker(long dataCenterId,
                        long workerId,
                        boolean clock,
                        long timeOffset,
                        boolean randomSequence)

基于Snowflake创建分布式ID生成器

Parameters:

dataCenterId - 数据中心ID,数据范围为0~255

workerId - 工作机器ID,数据范围为0~3

clock - true表示解决高并发下获取时间戳的性能问题

timeOffset - 允许时间回拨的毫秒量,建议5ms

randomSequence - true表示使用毫秒内的随机序列(超过范围则取余)

nextId

public Long nextId()

Description copied from interface: IdGenerator

获取下一个id

Specified by:

nextId in interface IdGenerator<Long>

Returns:

id
