Spring AMQP 项目是应用了spring的核心概念到AMQP协议消息解决方案中。咱们提供了一个“template”做为更高级别的抽象去发送和接收消息。我也提供了消息驱动类的支持。使用依赖注入和声明式编程能够更好的管理AMQP源代码。此项目中你能够看到和SpringFramework中JMS一些类似的地方。web
1.消息队列是应用程序和应用程序之间的一种通讯方法。spring
2.RabbitMQ : erlang语言开发、 基于AMQP协议。编程
3.同类产品:ActiveMQ、 ZeroMQ、 RabbitMQ、 RocketMQ、 Kafka。服务器
4.物理模型app
5.Broker 消息队列服务进程、 Exchange消息队列交换机,Queue 消息队列、 Producer 消息生产者、 Consumer 消息消费者。maven
6.六种模式: 简单模式、 工做模式、 发布与订阅模式、 路由模式、通配符模式、 远程调用模式(基本不会用到)。spring-boot
7.关键词:{Broker: 服务器实体、 Exchange :消息交换机、 Queue: 消息队列载体、Binding: 绑定 、Routing Key: 路由关键字、 VHost: 虚拟主机、Producer: 消息生产者 、 Consumer: 消息消费者、Channel: 消息通道 }测试
8.关键概念:由Exchange、Queue、RoutingKey三个才能决定一个从Exchange到Queue的惟一的线路。ui
这次是基于SpringBoot开发的RabbitMQ应用程序,利用SpringBoot的自动配置和起步依赖会让你更快更方便的构建项目。
让咱们实战开始。spa
