01-分布式基础-创建微服务项目

创建微服务项目

不推荐使用最新版本的springboot，springcloud Alibaba还未适配最新版

demo选用的版本：

maven父子项目

在父工程中声明依赖，控制子模块的中间件版本

study-cloud 负责声明3大组件版本

cloud子模块service负责声明其他中间件版本：zk、nacos等

父项目

创建springboot项目，不需要添加任何依赖，后期自己手动添加

点击下一步：

点击create创建项目如下：

修改项目结构

删除不需要的内容，只保留pom.xml文件和.idea文件

配置（pom.xml）

创建service

创建module

在父项（cloud-demo）上创建module

选择java项目

点击创建效果

修改配置

删除src

修改pom文件
