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

其他 2018-09-13 22:49:22 阅读次数: 0

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。

经排查是pom少引用了个包：

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-jdbc</artifactId>
