最后在网上发现资料解说：
地址：http://www.cnblogs.com/fightfordream/p/9048905.html
这个BUG我是通过修改 application.properties 中的 spring.rabbitmq.port 修复好的，这里我一开始使用了http的端口 15672，发生了上述异常。后面改成了 5672 可以成功连接。
映射2个端口：15672是Web管理界面的端口；5672是MQ访问的端口。
5672, 5671: used by AMQP 0-9-1 and 1.0 clients without and with TLS
15672: HTTP API clients and rabbitmqadmin (only if the management plugin is enabled)无法自动创建队列
无法创建队列，或者找不到声明的队列。
@Bean
public Queue queue() {
return new Queue(queue_name, true);
}这里是忘了注入队列的Bean了。
