關(guān)于SpringCloud整合RabbitMQ的實例

更新時間：2023年07月31日 10:07:11 作者：迷鹿小女子

這篇文章主要介紹了關(guān)于SpringCloud整合RabbitMQ的實例,消息隊列是指利用高效可靠的消息傳遞機(jī)制進(jìn)行與平臺無關(guān)的數(shù)據(jù)交流,并基于數(shù)據(jù)通信來進(jìn)行分布式系統(tǒng)的集成,是在消息的傳輸過程中保存消息的容器,需要的朋友可以參考下

SpringCloud整合RabbitMQ

注意一點，在發(fā)送消息的時候?qū)emplate進(jìn)行配置mandatory=tre保證監(jiān)聽有效

生產(chǎn)端還可以配置其他屬性，比如發(fā)送重試，超時時間、次數(shù)、間隔等

消費端核心配置

首先配置手工確認(rèn)模式，用于ACK的手工處理，這樣我們可以保證消息的可靠性送達(dá)，或者在消費端消費失敗的時候可以做到重回隊列、根據(jù)業(yè)務(wù)記錄日志等處理
可以設(shè)置消費端的監(jiān)聽個數(shù)和最大個數(shù)，用于控制消費端的并發(fā)情況

@RabbitListener注解的使用

消費端監(jiān)聽@RabbitListener注解，這個對于在實際工作中非常的好用

@RabbitListener是一個組合注解，里面可以注解配置（@QeeBinding、@Qee、@Exchange）直接通過這個組合注解一次性搞定消費端交換機(jī)、隊列、綁定、路由、并且配置監(jiān)聽功能等

注：由于類配置寫在代碼里非常不友好，所以強(qiáng)烈建議大家使用配置文件配置
