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
