RabbitMQ 的七種隊列模式和應(yīng)用場景

 更新時間：2021年05月26日 09:48:08   作者：我思知我在  
最近學(xué)習(xí)RabbitMQ，本文就記錄一下RabbitMQ 的七種隊列模式和應(yīng)用場景，方便以后使用,也方便和大家共享,相互交流

七種模式介紹與應(yīng)用場景

 簡單模式（Hello World）

在這里插入圖片描述

做最簡單的事情，一個生產(chǎn)者對應(yīng)一個消費(fèi)者，RabbitMQ相當(dāng)于一個消息代理，負(fù)責(zé)將A的消息轉(zhuǎn)發(fā)給B
應(yīng)用場景：將發(fā)送的電子郵件放到消息隊列，然后郵件服務(wù)在隊列中獲取郵件并發(fā)送給收件人

工作隊列模式（Work queues）

在這里插入圖片描述

在多個消費(fèi)者之間分配任務(wù)（競爭的消費(fèi)者模式），一個生產(chǎn)者對應(yīng)多個消費(fèi)者，一般適用于執(zhí)行資源密集型任務(wù)，單個消費(fèi)者處理不過來，需要多個消費(fèi)者進(jìn)行處理
應(yīng)用場景：一個訂單的處理需要10s，有多個訂單可以同時放到消息隊列，然后讓多個消費(fèi)者同時處理，這樣就是并行了，而不是單個消費(fèi)者的串行情況

訂閱模式（Publish/Subscribe）

在這里插入圖片描述

一次向許多消費(fèi)者發(fā)送消息，一個生產(chǎn)者發(fā)送的消息會被多個消費(fèi)者獲取，也就是將消息將廣播到所有的消費(fèi)者中。
應(yīng)用場景：更新商品庫存后需要通知多個緩存和多個數(shù)據(jù)庫，這里的結(jié)構(gòu)應(yīng)該是：

  • 一個fanout類型交換機(jī)扇出兩個個消息隊列，分別為緩存消息隊列、數(shù)據(jù)庫消息隊列
  • 一個緩存消息隊列對應(yīng)著多個緩存消費(fèi)者
  • 一個數(shù)據(jù)庫消息隊列對應(yīng)著多個數(shù)據(jù)庫消費(fèi)者

路由模式（Routing）

在這里插入圖片描述

有選擇地（Routing key）接收消息，發(fā)送消息到交換機(jī)并且要指定路由key ，消費(fèi)者將隊列綁定到交換機(jī)時需要指定路由key，僅消費(fèi)指定路由key的消息
應(yīng)用場景：如在商品庫存中增加了1臺iphone12，iphone12促銷活動消費(fèi)者指定routing key為iphone12，只有此促銷活動會接收到消息，其它促銷活動不關(guān)心也不會消費(fèi)此routing key的消息

主題模式（Topics）

在這里插入圖片描述

根據(jù)主題（Topics）來接收消息，將路由key和某模式進(jìn)行匹配，此時隊列需要綁定在一個模式上，#匹配一個詞或多個詞，*只匹配一個詞。
應(yīng)用場景：同上，iphone促銷活動可以接收主題為iphone的消息，如iphone12、iphone13等

遠(yuǎn)程過程調(diào)用（RPC）

在這里插入圖片描述

如果我們需要在遠(yuǎn)程計算機(jī)上運(yùn)行功能并等待結(jié)果就可以使用RPC，具體流程可以看圖。
應(yīng)用場景：需要等待接口返回數(shù)據(jù)，如訂單支付

發(fā)布者確認(rèn)（Publisher Confirms）

與發(fā)布者進(jìn)行可靠的發(fā)布確認(rèn)，發(fā)布者確認(rèn)是RabbitMQ擴(kuò)展，可以實現(xiàn)可靠的發(fā)布。在通道上啟用發(fā)布者確認(rèn)后，RabbitMQ將異步確認(rèn)發(fā)送者發(fā)布的消息，這意味著它們已在服務(wù)器端處理
應(yīng)用場景：對于消息可靠性要求較高，比如錢包扣款

代碼演示：

代碼中沒有對后面兩種模式演示，有興趣可以自己研究

四種交換機(jī)介紹

直連交換機(jī)（Direct exchange）：具有路由功能的交換機(jī)，綁定到此交換機(jī)的時候需要指定一個routing_key，交換機(jī)發(fā)送消息的時候需要routing_key，會將消息發(fā)送道對應(yīng)的隊列
扇形交換機(jī)（Fanout exchange）：廣播消息到所有隊列，沒有任何處理，速度最快
主題交換機(jī)（Topic exchange）：在直連交換機(jī)基礎(chǔ)上增加模式匹配，也就是對routing_key進(jìn)行模式匹配，*代表一個單詞，#代表多個單詞
首部交換機(jī)（Headers exchange）：忽略routing_key，使用Headers信息（一個Hash的數(shù)據(jù)結(jié)構(gòu)）進(jìn)行匹配，優(yōu)勢在于可以有更多更靈活的匹配規(guī)則

總結(jié)

這么多種隊列模式中都有其應(yīng)用場景，大家可以根據(jù)應(yīng)用場景示例中進(jìn)行選擇
