RabbitMQ与spring结合之spring-rabbit使用（三）

RabbitMQ的使用相对简单，但是当我们在实际开发过程中同样会感觉麻烦，所以spring团队对RabbitMQ进行了封装，使其使用更加简单，更适合生产环境使用。

<!-- 定义RabbitMQ的连接工厂 -->
<rabbit:connection-factory id="connectionFactory"
host="127.0.0.1" port="5672" username="root" password="root"

<!-- 定义Rabbit模板，指定连接工厂以及定义exchange -->
<rabbit:template id="amqpTemplate" connection-factory="connectionFactory" exchange="fanoutExchange" />
<!-- <rabbit:template id="amqpTemplate" connection-factory="connectionFactory"
exchange="fanoutExchange" routing-key="foo.bar" /> -->


<!-- MQ的管理，包括队列、交换器等 -->
<rabbit:admin connection-factory="connectionFactory" />
