Spring Cloud Alibaba搭建(一)：依赖版本选择

一、版本选择：官方已经提供了无冲突版本，有两个查看方式

1.GitHub：

打开Spring Cloud Alibaba项目的github地址，选择wiki,再点击右侧的”版本说明“

由于主要是学习作用，所以此处直接选择最新版本，实际请根据需要选择！

2.spring官网

spring cloud 和 spring boot的依赖关系选择

进入官网–>选择Projects—> Spring Cloud–>learn–>选择对应版本的Reference Doc

spring cloud alibaba参考文档

二、创建空项目配置依赖

1.创建空项目，用于配置公共依赖

2.xml配置

注：利用 dependencyManagement 多版本继承之后，parent一般用于填写自己公司的基础依赖了（有的话）
