springboot中通过lua脚本来获取序列号的方法

序言：

事件：此web项目的功能及其简单，就是有客户端来访问redis序列号服务时发送jison报文，项目已经在测试环境成功运行2周了，具体的代码我就直接上了，此博客仅是自己的记录，同学们可做参考！

一、工程目录结构

二、配置文件

1、pom.xml

2、applicaiton.properties

spring.redis.database= 0
spring.redis.host= 127.0.0.1
spring.redis.port= 6379
spring.redis.pool.max-active= 8
spring.redis.pool.max-wait= -1ms
spring.redis.pool.max-idle= 8
spring.redis.pool.min-idle= 0
spring.redis.pool.timeout= 2000ms
server.port= 8085

3、luaScripts脚本

local function get_next_seq()
--KEYS[1]:第一个参数代表存储序列号的key 相当于代码中的业务类型
local key = tostring(KEYS[1])
--KEYS[2]:第二个参数代表序列号增长速度
local incr_amoutt = tonumber(KEYS[2])
--KEYS[3]`:第四个参数为序列号 (yyMMddHHmmssSSS + 两位随机数)
local seq = tonumber(KEYS[3])
--序列号过期时间大小,单位是秒
-- local month_in_seconds = 24 * 60 * 60 * 7

--Redis的 SETNX 命令可以实现分布式锁,用于解决高并发
--如果key不存在,将 key 的值设为 seq，设置成成功返回1 未设置返回0
--若给定的 key 已经存在，则 SETNX 不做任何动作，获取下一个按照步增的值

if (1 == redis.call('setnx', key, seq)) --不存在key，
then
--设置key的生存时间 为 month_in_seconds秒
-- 由于序列号需要永久有效，不能过期，所以取消这个设置，需要的可以取消注释
-- redis.call('expire', key, month_in_seconds)
--将序列返回给调用者
 return seq
else
--key值存在,直接获取下一个增加的值
 local nextSeq = redis.call('incrby', key, incr_amoutt)
 return nextSeq
end
end
return get_next_seq()
