首先是创建一个springboot的项目,pom.xml内容如下:
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

<properties>

<dependencies>
<!-- 这个是flyway的核心,导入后springboot会自动进行管理,版本不是最新的 -->

<!-- 扩展插件,mybatis-plus,该依赖会自动导入mybatis -->

然后再让我们看看application.properties
