背景
在项目中需要一个统一的拿单号等唯一ID的服务就想起了之前用到的leaf但是因为项目要求leaf的版本不符合需要做一些升级
项目地址https://github.com/Meituan-Dianping/Leaf
升级点
1去掉leaf-core项目中pom.xml中的properties配置统一到parent项目中。
因为都是公用的所以可以直接去掉。
2leaf-server项目中改成 spring-boot-dependencies.version2.7.17/spring-boot-dependencies.version 3修改leaf项目的leaf-parent pom.xml文件 spring.version5.3.31/spring.version druid.version1.2.5/druid.version mysql-connector-java.version8.0.30/mysql-connector-java.version 完成上面3个修改点就可以了

解决方法
1创建目录/tmp/hub-leaf/leafconf/8102/ (这个8102就是在上面启动配置中的那个port)
2, 创建文件workerID.properties, 内容为workerID1
再去启动就可以了。 代码地址
https://download.csdn.net/download/wangerrong/88585488
测试
1拿整数ID单号http://localhost:8101/api/segment/get/order_no_seq order_no_seq是leaf_alloc表中新增的biz_tag
2拿雪花算法的ID单号: http://localhost:8101/api/snowflake/get/test (test是可以自己改的一般是业务场景需要的比如order)
3查看单号缓存的监控http://localhost:8101/cache
