feature

1- to be more resilient i suggest using Apache Kafka as a service-to-service communication and also replace the queue to Zipkin
2- add Event Sourcing

it is a good example but...

if it is a maven project , is is better more.do you wanna create a new one ?

Could you please upgrade your project now ?

如何理解“Be of the web, not behind the web”

在老外眼里，所有的微服务都是基于rest api。俗话说：

Be of the web, not behind the web

-- Ian Robinson

请问，你如何对比rest api和dubbo中soa接口的优劣。

先抛点砖：
1，部署方面，rest api和db可放入同一进程，避免dubbo的3个进程：1，soa一个进程；2，admin一个；3，http 一个。
2，微服务划分自然，soa是中间抽象。增加了复杂度和调用链条。
3，rest api跨平台和语言；soa基本用java，而且要提供api.jar，版本管理即使用maven私服也容易出问题。
4，rest api较慢，但计算机硬件的发展会掩盖这一点。

rabbit mq 和 zipkin 是如何交互的，service-a 和b 是如何和mq交互的，从源代码中看不出来呀

如题，谢谢！
