application.yml

server:
  port: 1234
spring:
  datasource:
    driver-class-name: com.mysql.cj.jdbc.Driver
    password: root
    url: jdbc:mysql://localhost:3306/demo?serverTimezone=UTC&allowMultiQueries=true&useUnicode=true&characterEncoding=UTF-8&useSSL=false
    username: root
  flyway:
    baseline-on-migrate: true
    enabled: true
    locations: classpath:/db/migration

必须在resource下新建这个名称的文件夹，sql脚本的命名规则 ： V${版本号}__${描述}.sql

启动后，不仅会把你脚本的表创建好，同时还会创建{flyway_schema_history}表，记录的就是操作日志，之后初始化执行一次

 如果启动过程中，报错 .idea中flyway-core.xml提示Message: 前言中不允许有内容，修改一下即可
