序言：

事件：此web項(xiàng)目的功能及其簡(jiǎn)單，就是有客戶(hù)端來(lái)訪(fǎng)問(wèn)redis序列號(hào)服務(wù)時(shí)發(fā)送jison報(bào)文，項(xiàng)目已經(jīng)在測(cè)試環(huán)境成功運(yùn)行2周了，具體的代碼我就直接上了，此博客僅是自己的記錄，同學(xué)們可做參考！

一、工程目錄結(jié)構(gòu)

二、配置文件

1、pom.xml

3、luaScripts腳本

local function get_next_seq() --KEYS[1]:第一個(gè)參數(shù)代表存儲(chǔ)序列號(hào)的key 相當(dāng)于代碼中的業(yè)務(wù)類(lèi)型 local key = tostring(KEYS[1]) --KEYS[2]:第二個(gè)參數(shù)代表序列號(hào)增長(zhǎng)速度 local incr_amoutt = tonumber(KEYS[2]) --KEYS[3]`:第四個(gè)參數(shù)為序列號(hào) (yyMMddHHmmssSSS + 兩位隨機(jī)數(shù)) local seq = tonumber(KEYS[3]) --序列號(hào)過(guò)期時(shí)間大小,單位是秒 -- local month_in_seconds = 24 * 60 * 60 * 7 --Redis的 SETNX 命令可以實(shí)現(xiàn)分布式鎖,用于解決高并發(fā) --如果key不存在,將 key 的值設(shè)為 seq，設(shè)置成成功返回1 未設(shè)置返回0 --若給定的 key 已經(jīng)存在，則 SETNX 不做任何動(dòng)作，獲取下一個(gè)按照步增的值 if (1 == redis.call(’setnx’, key, seq)) --不存在key， then --設(shè)置key的生存時(shí)間 為 month_in_seconds秒 -- 由于序列號(hào)需要永久有效，不能過(guò)期，所以取消這個(gè)設(shè)置，需要的可以取消注釋 -- redis.call(’expire’, key, month_in_seconds) --將序列返回給調(diào)用者 return seq else --key值存在,直接獲取下一個(gè)增加的值 local nextSeq = redis.call(’incrby’, key, incr_amoutt) return nextSeq endendreturn get_next_seq()
