i found some different feature about technical stack between hangzhou and shenzheng. at hangzhou , many compary use dubbo as their micro-service framework. but at shenzhen , a numbers of company use SpringCloud as their micro-service framework.

    according my work expirences, in the past, i fouce attection on Dubbo. but now , i need spend more attention on SpringCloud.

    it’good practice starting a quickstart, learning any technical, and springCloud is based on SpringBoot , namely, it’s maybe more easy than others framework . so , first, i must find the corrent version between springCloud and springBoot.

    after Google it , i found a document describing it. https://spring.io/projects/spring-cloud
