我在部署的 grails 应用程序中配置与 CloudAMQP 的连接时遇到困难。我可以针对本地安装的 RabbitMQ 实例在本地运行应用程序，但无法弄清楚如何正确定义我的应用程序以使用 CloudAMQP 服务在 CloudBees 上运行。
在我的 Config.groovy 中，我定义了我的连接信息和一个队列：
rabbitmq {
connectionfactory {
username = 'USERNAME'
password = 'PASSWORD'
hostname = 'lemur.cloudamqp.com'
}
queues = {
testQueue autoDelete: false, durable: false, exclusive: false
}
}
当应用程序启动并尝试连接时，我看到以下日志消息：
2013-08-23 21:29:59,195 [main] DEBUG listener.SimpleMessageListenerContainer - Starting Rabbit listener container.
2013-08-23 21:29:59,205 [SimpleAsyncTaskExecutor-1] DEBUG listener.BlockingQueueConsumer - Starting consumer Consumer: tag=[null], channel=null, acknowledgeMode=AUTO local queue size=0
2013-08-23 21:30:08,405 [SimpleAsyncTaskExecutor-1] WARN listener.SimpleMessageListenerContainer - Consumer raised exception, processing can restart if the connection factory supports it
