基于spring的RabbitMQ发送QQ邮件

RabbitMQ基本概念：
1.Message:消息，由消息头和消息体组成
2.Publisher:生产者（消息发布者）
3.Exchange:交换器接收生产者发布的消息并传给队列
4.Binding:绑定，基于路由键将交换器和消息队列连接起来的路由规则
5.Queue:消息队列
6.Connection:网络连接，例如TCP
7.Channel:信道，新建或销毁TCP太消耗资源，引入信道以复用一个TCP
8.Consumer:消费者，从消息队列中获取消息的客户端应用
9.Virtual Host:共享相同身份认证和加密环境的独立服务器域
10.Broker:消息队列服务器实体
