一、简单对象

1. 依赖

       <!--spring整合rabbitmq-->
       <dependency>
            <groupId>org.springframework.amqp</groupId>
            <artifactId>spring-rabbit</artifactId>
            <version>2.0.1.RELEASE</version>
        </dependency>

注：maven方式，这一个依赖即可，如果是非maven项目，需要引入5个jar如下：
在这里插入图片描述
推荐使用mavne方式，简单，非Maven项目，先用maven把以来下载本地仓库，复制到非maven的项目中即可。
