Java generate globally unique ID code demo

I have seen two algorithm programs for generating unique IDs on GitHub (one from Baidu and the other from meituan) and intend to run them. As for the principles, the documents are very detailed. I won't paste them one by one here. I only demonstrate the code here

Baidu uid generator

Maven dependency

SQL script

Mapper file

application. YML configuration

Spring bean configuration

test

Meituan uid generator

Maven dependency

Spring bean configuration

test

Personally, I think it's easier to use Baidu's (wow Kaka o (∩ 8745;) O haha ~)

There is also a redis solution, which feels good
