Spring Boot集成Redis Stream消息隊(duì)列從入門到實(shí)戰(zhàn)指南
在現(xiàn)代分布式系統(tǒng)中,消息隊(duì)列是實(shí)現(xiàn)系統(tǒng)解耦、異步處理和流量削峰的重要組件。Redis Stream作為Redis 5.0引入的新數(shù)據(jù)類型,提供了完整的消息隊(duì)列功能,成為輕量級(jí)消息中間件的優(yōu)秀選擇。
前言
早期我使用 redis pubsub 的方式實(shí)現(xiàn)了消息訂閱,但是在使用過(guò)程,發(fā)現(xiàn)如果部署多實(shí)例將會(huì)重復(fù)處理消息事件,導(dǎo)致業(yè)務(wù)重復(fù)處理的情況。
根本原因是 redis pubsub 都是直接廣播,無(wú)法控制多實(shí)例重復(fù)訂閱消息的情況。
為了解決這個(gè)問(wèn)題,則需要改動(dòng) Redis Stream 的方式來(lái)構(gòu)建消息隊(duì)列。
以下我分別三個(gè)案例逐步實(shí)踐,達(dá)到一個(gè)可以適應(yīng)生產(chǎn)環(huán)境要求的成熟方案:
- 簡(jiǎn)單使用 StringRedisTemplate 構(gòu)建一個(gè)消費(fèi)隊(duì)列
- 使用 StringRedisTemplate 構(gòu)建多個(gè)消費(fèi)隊(duì)列
- 使用 RedissonClient 構(gòu)建多個(gè)消費(fèi)隊(duì)列,包含消費(fèi)隊(duì)列的運(yùn)維監(jiān)控、消費(fèi)隊(duì)列查詢/重置 等功能
一、Redis Stream簡(jiǎn)介與核心特性
Redis Stream是Redis 5.0版本專門為消息隊(duì)列場(chǎng)景設(shè)計(jì)的數(shù)據(jù)結(jié)構(gòu),它借鑒了Kafka的設(shè)計(jì)理念,提供了消息持久化、消費(fèi)者組和消息確認(rèn)機(jī)制等核心功能。
Redis Stream核心優(yōu)勢(shì)
- 高性能:基于內(nèi)存操作,吞吐量高
- 持久化:消息可持久化保存,支持RDB和AOF
- 消費(fèi)者組:支持多消費(fèi)者負(fù)載均衡,確保消息不被重復(fù)消費(fèi)
- 阻塞操作:支持類似Kafka的長(zhǎng)輪詢機(jī)制
Redis Stream基礎(chǔ)操作示例
1. 添加消息到Stream
# 自動(dòng)生成消息ID XADD mystream * name "訂單創(chuàng)建" order_id "1001" amount "299.99" # 限制Stream最大長(zhǎng)度(保留最新1000條消息) XADD mystream MAXLEN 1000 * name "訂單支付" order_id "1001"
2. 查詢消息
# 查詢所有消息 XRANGE mystream - + # 分頁(yè)查詢,每次返回10條 XRANGE mystream - + COUNT 10 # 反向查詢(從新到舊) XREVRANGE mystream + - COUNT 5
3. 監(jiān)控新消息
# 阻塞監(jiān)聽新消息(0表示不超時(shí)) XREAD BLOCK 0 STREAMS mystream $
二、Spring Boot 簡(jiǎn)單集成案例
1. 添加依賴

跟案例1的操作一致,以發(fā)送訂單消息的事件作為驗(yàn)證示例
8.1 通過(guò)修改端口號(hào),啟動(dòng)多個(gè)實(shí)例
實(shí)例1
server: port: 8083
實(shí)例2

8.2 發(fā)送訂單事件消息,查看實(shí)例日志,確認(rèn)事件未被重復(fù)消費(fèi)
實(shí)例1

實(shí)例2

可以看到只有一個(gè)實(shí)例處理 1764865303698-0 事件,并沒有被重復(fù)消費(fèi)
9.觸發(fā)多個(gè)消息,造成堵塞,檢查告警日志

模擬大量出現(xiàn)訂閱消息,導(dǎo)致事件堵塞的情況。
10. Redis 查看隊(duì)列消息

10.5 查詢隊(duì)列總數(shù)
172.17.0.6:6379> XLEN order_stream (integer) 141 172.17.0.6:6379>
11. 總結(jié)
上面的項(xiàng)目是通過(guò) StringRedisTemplate 做隊(duì)列消息的讀取,有些時(shí)候項(xiàng)目不能直接使用。
@Autowired private StringRedisTemplate stringRedisTemplate;
所以下一章節(jié),我將會(huì)使用 RedissonClient 來(lái)做替代實(shí)現(xiàn)的方法,增加符合生產(chǎn)環(huán)境使用,并且還會(huì)增加消息隊(duì)列總數(shù)的監(jiān)控、查詢消息隊(duì)列總數(shù)接口、清除消息隊(duì)列的運(yùn)維接口。
四、SpringBoot 使用 RedissonClient 集成 Redis Stream 進(jìn)階:配置多個(gè)消費(fèi)組
