阿里云rocketmq简单接入

直接上代码
参考文档：阿里云rocketmq
配置文件：

rocketmq:
  access-key:  // AccessKeyId 阿里云身份验证，在阿里云用户信息管理控制台获取。
  secret-key: // AccessKeySecret 阿里云身份验证，在阿里云用户信息管理控制台获取。
  consume-thread-nums: //消费者线程数
  wangfa-name-srv-addr:  // 设置TCP接入域名，进入消息队列RocketMQ版控制台实例详情页面的接入点区域查看。
  wangfa-group-id: // 您在控制台创建的Group ID。
  wangfa-topic: // 普通消息所属的Topic，切勿使用普通消息的Topic来收发其他类型的消息。
  wangfa-tag: // Message Tag可理解为Gmail中的标签，对消息进行再归类，方便Consumer指定过滤条件在消息队列RocketMQ版的服务器过滤。
                    // Tag的具体格式和设置方法，请参见Topic与Tag最佳实践。
