分布式ID生成框架Leaf升级踩坑

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。

2，leaf-server项目中改成

<spring-boot-dependencies.version>2.7.17</spring-boot-dependencies.version>

3，修改leaf项目的leaf-parent pom.xml文件

<spring.version>5.3.31</spring.version>
<druid.version>1.2.5</druid.version>
<mysql-connector-java.version>8.0.30</mysql-connector-java.version>

完成上面3个修改点，就可以了

启动配置：

leaf.name=xxx-leaf
leaf.segment.enable=true
leaf.jdbc.url=jdbc:mysql://xxx.xxx.xxx.xxx:3306/leaf?autoReconnect=true&allowMultiQueries=true&useSSL=false&useUnicode=true&characterEncoding=UTF8&serverTimezone=UTC&useLocalSessionState=true
leaf.jdbc.username=root
leaf.jdbc.password=xxxxxx

leaf.snowflake.enable=true
leaf.snowflake.zk.address=xxx.xxx.xxx.xxx:2181
leaf.snowflake.port=8102

遇到的问题：
