-为了便于区分不同的运行实例，在体质指数计算器的实现中新增了返回实例ID和运行时间的接口，详情可查看[体质指数计算器的完整实现代码](https://github.com/apache/servicecomb-java-chassis/tree/master/samples/bmi/calculator)。而为了避免端口冲突，新的实例在另一个端口上运行。

### 体质指数计算器实现
体质指数计算器提供运算服务，其实现分为三部分：

-To better distinguish different running instances, we added a new interface that returns instance id in the implementation of BMI calculator, details can refer to [the implementation of BMI calculator](https://github.com/apache/servicecomb-java-chassis/tree/master/samples/bmi/calculator). Besides, a different service port is needed to avoid port conflict.
