RabbitMQ:第一章:6 种工作模式以及消息确认机制(理论与代码相结合)
RabbitMQ:第二章:Spring整合RabbitMQ(简单模式,广播模式,路由模式,通配符模式,消息可靠性投递,防止消息丢失,TTL,死信队列,延迟队列,消息积压,消息幂等性)
RabbitMQ:第三章:Springboot集成RabbitMQ(直连模式,工作队列模式,发布订阅模式,路由模式,通配符模式
提示:Springboot集成Rabbitmq实战案例,通过接口调用的方式演示。
提示:以下是本篇文章正文内容,下面案例可供参考
创建生产者SpringBoot工程
引入pom依赖
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-amqp</artifactId>
</dependency>
编写rabbitmq配置消息
定义交换机,队列以及绑定关系的配置类
注入RabbitTemplate,调用方法,完成消息发送
