Eden

项目搭建

使用IDEA初始化一个SpringBoot项目

创建统一的父工程：eden，用来管理依赖及其版本，注意是创建project，而不是moudle

填写项目信息：

注意：
父工程不需要代码，只是管理依赖，因此我们不选择任何SpringCloud的依赖
跳过依赖选择。

填写保存的位置信息：

添加项目依赖

在pom.xml中添加相关依赖。

<properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>

修改SpringBoot配置文件

在application.yml中添加数据源配置和MyBatis的mapper.xml的路径配置。

server:
  port: 8080

spring:
  datasource:
    url: jdbc:mysql://localhost:3306/mall?useUnicode=true&characterEncoding=utf-8&serverTimezone=Asia/Shanghai
    username: root
    password: root

mybatis:
  mapper-locations:
    - classpath:mapper/*.xml
    - classpath*:com/**/mapper/*.xml
