簡(jiǎn)介
rabbitmq是實(shí)現(xiàn)amqp（高級(jí)消息隊(duì)列協(xié)議）的消息中間件的一種，用于在分布式系統(tǒng)中存儲(chǔ)轉(zhuǎn)發(fā)消息，在易用性、擴(kuò)展性、高可用性等方面表現(xiàn)不俗
概念：
- 生產(chǎn)者 消息的產(chǎn)生方，負(fù)責(zé)將消息推送到消息隊(duì)列
- 消費(fèi)者 消息的最終接受方，負(fù)責(zé)監(jiān)聽(tīng)隊(duì)列中的對(duì)應(yīng)消息，消費(fèi)消息
- 隊(duì)列 消息的寄存器，負(fù)責(zé)存放生產(chǎn)者發(fā)送的消息
- 交換機(jī) 負(fù)責(zé)根據(jù)一定規(guī)則分發(fā)生產(chǎn)者產(chǎn)生的消息
- 綁定 完成交換機(jī)和隊(duì)列之間的綁定
模式：
- direct：直連模式，用于實(shí)例間的任務(wù)分發(fā)
- topic：話題模式，通過(guò)可配置的規(guī)則分發(fā)給綁定在該exchange上的隊(duì)列
- headers：適用規(guī)則復(fù)雜的分發(fā)，用headers里的參數(shù)表達(dá)規(guī)則
- fanout：分發(fā)給所有綁定到該exchange上的隊(duì)列，忽略routing key
springboot集成rabbitmq

<dependency> <groupid>org.springframework.boot</groupid> <artifactid>spring-boot-starter-amqp</artifactid> <version>1.5.2.release</version></dependency> |
二、配置application.properties

body = json.tojsonstring(issuemessage).getbytes(amqpconfiguration.message_encoding); rabbittemplate.convertandsend(amqpconfiguration.exchange_issue, amqpconfiguration.routing_key_issue_user, body); |
四、編寫消費(fèi)者
