spring amqp rabbitmq fanout配置

基于spring amqp rabbitmq fanout配置如下：

发布端

<rabbit:connection-factory id="rabbitConnectionFactory" username="guest" password="guest" host="localhost" port="5672"/>
<rabbit:template id="amqpTemplate" connection-factory="rabbitConnectionFactory" exchange="fanout-mq-exchange" message-converter="jsonMessageConverter"/>
<rabbit:admin id="admin" connection-factory="rabbitConnectionFactory"/>
<bean id="jsonMessageConverter" class="org.springframework.amqp.support.converter.Jackson2JsonMessageConverter" />

<rabbit:queue id="fanout_queue" name="fanout_queue" durable="true" auto-delete="false" exclusive="false" />
<rabbit:queue id="fanout_queue1" name="fanout_queue1" durable="true" auto-delete="false" exclusive="false" />
<rabbit:queue id="fanout_queue2" name="fanout_queue2" durable="true" auto-delete="false" exclusive="false" />

<rabbit:fanout-exchange id="fanout-mq-exchange" name="fanout-mq-exchange" durable="true" auto-delete="false">
<rabbit:bindings>
<rabbit:binding queue="fanout_queue"/>
<rabbit:binding queue="fanout_queue1"/>
<rabbit:binding queue="fanout_queue2"/>
</rabbit:bindings>
</rabbit:fanout-exchange>

消费端

<rabbit:fanout-exchange id="fanout-mq-exchange" name="fanout-mq-exchange" durable="true" auto-delete="false">

事实上这种配置仅适用于中小型规模、服务器数量能够提前预估的环境，对于服务器数量不可提前确定或者经常可能发生变化的环境，并不适合采用配置式，而是在容器启动时进行动态注册。并且queue的属性应该为exclusive+auto-delete。
