如何让 Spring RabbitMQ 创建一个新的队列? [英] How to get Spring RabbitMQ to create a new Queue?

问题描述

根据我对 rabbit-mq 的(有限)经验，如果您为尚不存在的队列创建新侦听器，则会自动创建该队列.我正在尝试使用带有 rabbit-mq 的 Spring AMQP 项目来设置侦听器，但出现错误.这是我的 xml 配置:

In my (limited) experience with rabbit-mq, if you create a new listener for a queue that doesn't exist yet, the queue is automatically created. I'm trying to use the Spring AMQP project with rabbit-mq to set up a listener, and I'm getting an error instead. This is my xml config:

<rabbit:connection-factory id="rabbitConnectionFactory" host="172.16.45.1" username="test" password="password" />

<rabbit:listener-container connection-factory="rabbitConnectionFactory"  >
    <rabbit:listener ref="testQueueListener" queue-names="test" />
</rabbit:listener-container>

<bean id="testQueueListener" class="com.levelsbeyond.rabbit.TestQueueListener"> 
</bean>

我在我的 RabbitMq 日志中得到了这个:

I get this in my RabbitMq logs:

=ERROR REPORT==== 3-May-2013::23:17:24 ===
connection <0.1652.0>, channel 1 - soft error:
{amqp_error,not_found,"no queue 'test' in vhost '/'",'queue.declare'}

来自 AMQP 的类似错误:

And a similar error from AMQP:

2013-05-03 23:17:24,059 ERROR [org.springframework.amqp.rabbit.listener.SimpleMessageListenerContainer] (SimpleAsyncTaskExecutor-1) - Consumer received fatal exception on startup
org.springframework.amqp.rabbit.listener.FatalListenerStartupException: Cannot prepare queue for listener. Either the queue doesn't exist or the broker will not allow us to use it.

从堆栈跟踪看来，队列是在被动"模式下创建的 - 谁能指出我将如何创建队列而不使用被动模式，所以我没有看到这个错误?还是我错过了什么?

It would seem from the stack trace that the queue is getting created in a "passive" mode- Can anyone point out how I would create the queue not using the passive mode so I don't see this error? Or am I missing something else?

推荐答案

似乎可以解决我的问题的是添加管理员.这是我的 xml:

What seemed to resolve my issue was adding an admin. Here is my xml:

<rabbit:listener-container connection-factory="rabbitConnectionFactory"  >
    <rabbit:listener ref="orderQueueListener" queues="test.order" />
</rabbit:listener-container>

<rabbit:queue name="test.order"></rabbit:queue>

<rabbit:admin id="amqpAdmin" connection-factory="rabbitConnectionFactory"/>

<bean id="orderQueueListener" class="com.levelsbeyond.rabbit.OrderQueueListener">   
</bean>
