消息中间件系列四：RabbitMQ与Spring集成

Posted 2021-01-08 小不点啊

一、RabbitMQ与Spring集成

 准备工作：

分别新建名为RabbitMQSpringProducer和RabbitMQSpringConsumer的maven web工程

 在pom.xml文件里面引入如下依赖：

与Spring集成步骤：

配置文件中增加命名空间:
xmlns:rabbit="http://www.springframework.org/schema/rabbit"
http://www.springframework.org/schema/rabbit
http://www.springframework.org/schema/rabbit/spring-rabbit-2.0.xsd

配置文件中的配置
1) 连接工厂配置
2) <rabbit:admin>
3) 声明队列
4) 声明交换器
5) 队列和交换器进行绑定
6) 生产者端要声明RabbitmqTemplate

1. 在工程RabbitMQSpringProducer里面新建/RabbitMQSpringProducer/src/main/java/applicationContext.xml的配置文件
