概述：
温馨提示：
当前Spring Cloud Alibaba 的0.2.1RELEASE 版本基于Spring Cloud Finchley（F）
开发，故在做选择Spring boot 版本时不要使用2.1.0以及以上的版本（因为2.1.x版本
必须使用Spring Cloud Greenwich）俗称G版，请使用官方Demo中使用的2.0.6.RELEASE，以免发生意想不到的问题（比如无法注册到服务器）。
Spring Cloud Alibaba 项目都是基于Spring Cloud，而Spring Cloud项目都是基于Spring Cloud，而sprigCloud又都是基于Spring boot进行开发，并且都使用Maven做项目管理工具。在实际开发中，我们一般都会创建一个依赖管理项目作为Maven的 Parent 项目使用，这样我们可以极大的方便我们对jar 包版本进行统一管理。

parent:集成了SPring boot 的Parent，标识我们是一个springboot
工程
package: pom ，表示该项目仅仅当做依赖项目，没有具体的实现代码
spring-cloud-alibaba-dependencies: 在PROPERTIES 配置中
预定义了版本号为0.2.1.RELEASE, 表示我们的Spring boot Alibaba对应的是 Spring cloud Finchley版本
build：配置了该项目所需要的各种插件
repositories: 配置项目下载依赖时的第三方库。
依赖版本说明
项目的最新版本是 0.2.1.RELEASE 和 0.1.1.RELEASE，版本 0.2.1.RELEASE 对应的是 Spring Cloud Finchley 版本，版本 0.1.1.RELEASE 对应的是 Spring Cloud Edgware 版本。
与 Spring Cloud Netflix 的区别
主要增加了 org.springframework.cloud:spring-cloud-alibaba-dependencies
