项目介绍

基于zookeeper和snowflake算法的分布式id生成器

使用方法

1. 添加pom依赖

   <dependency>
       <groupId>cn.waynechu</groupId>
       <artifactId>biz-boot-starter-sequence</artifactId>
   </dependency>
   

2. 添加配置

   sequence.enable=true
   sequence.registryFile=./tmp/sequence
   sequence.zookeeper.serverLists=localhost:2181,localhost:2182,localhost:2183
   sequence.zookeeper.namespace=sequence
   

3. 注入IdGenerator对象

   @Autowire
   private IdGenerator idGenerator;
   

4. 生成分布式id

   long id = idGenerator.nextId();
   long[] ids = idGenerator.nextIds(1000);
   String idStr = idGenerator.nextStringId();
   String[] idsStr = idGenerator.nextStringIds(1000);
   ...
   

其他解决方案

1. 基于UUID
2. Redis分布式自增ID
3. 百度UID-Generator，支持雪花ID模式。https://github.com/baidu/uid-generator
4. 美团Leaf分布式ID生成器，支持号段模式和雪花ID模式。https://github.com/Meituan-Dianping/Leaf
