[麦芽项目 day one] 一、初步搭建SpringBoot+Druid环境

准备搞一套springcloud的电商全套，在这里记录下，每次所做的，这样可以有所沉淀。

首先搭建整体项目，技术采用：springcloud全家桶+mybatis+druid+rabbitmq+xxljob+elasticsearch

模块包括：用户模块、购物车模块、商品模块、订单模块、基础服务模块、接口模块、后台管理模块.....等

先解决掉用户模块。

application-dev.yml配置如下（主要是druid数据源的配置）：

刚开始启动报错：

经排查是pom少引用了个包：

    org.springframework.boot
    spring-boot-starter-jdbc


成功后：
