使用的是spring-rabbitmq，启动tomcate报错，消费这队列找不到，如果队列不存在消费者会自动创建的
Caused by: org.springframework.amqp.AmqpIllegalStateException: Fatal exception on listener startup
Caused by: org.springframework.amqp.rabbit.listener.QueuesNotAvailableException: Cannot prepare queue for listener. Either the queue doesn’t exist or the broker will not allow us to use it.
xml加上如下配置就可以了自动创建了
