Spring Boot集成flyway中遇到的问题
问题一
使用flyway中总是提示flyway插件为引入，但pom中已经放入了
最后在网上找了一圈没发现需要放入数据库连接的各种信息
如果在URL后不加入
?serverTimezone=UTC
则会出现错误：
The server time zone value '???ú±ê×??±??' is unrecognized or represents more than one time zone.
完整代码：
org.flywaydb
flyway-maven-plugin
root
password
com.mysql.cj.jdbc.Driver
jdbc:mysql://127.0.0.1:3306/db?serverTimezone=UTC
true
classpath:db/migration/
问题二
flyway成功运行了，数据库也出现了相应的table
但控制台出现这个错误，虽然看着好像不会有什么影响

但本着干掉全部BUG（其实是强迫症犯了），将其解决了
问题出在MySQL与驱动版本不匹配，换成相同版本即可
查看MySQL版本
打开命令行cmd执行以下语句
- cd C:\Program Files\MySQL\MySQL Server 8.0
- cd bin
- mysql -uroot -p(密码)
- status
然后就能看到你的版本号了，然后在pom中指定driver的版本号即可消除这个错误
