FlywayException：不支持的数据库：MariaDB 10.5

Question

• mariadb版本为服务器版本：10.5.9-MariaDB Homebrew
• Flyway 版本是 "org.flywaydb" % "flyway-core" % "8.2.1"
• HikariCP 版本为 "com.zaxxer" % "HikariCP" % "5.0.1"
• Mariadb jdbc 客户端版本为 "org.mariadb.jdbc" % "mariadb-java-client" % "2.7.5",

这是一个 spring boot 应用程序，当我启动应用程序时出现以下错误

8.2.1 及以上的 flyway-core 版本给我同样的错误。

flyway-core最新版本为8.4.3。基于以下链接

https://mvnrepository.com/artifact/org.flywaydb/flyway-core

我还尝试将 mariadb-java-client 升级到最新版本 3.0.3

https://mvnrepository.com/artifact/org.mariadb.jdbc/mariadb-java-client

但是当 flyway-core 的版本降级到 8.2.0 时，就可以了

"org.flywaydb" % "flyway-core" % "8.2.0",

我还通过 flyway 文档中的以下链接

https://flywaydb.org/documentation/database/mariadb

这是否意味着 flyway 的支持只支持到 mariadb 10.4 版本？

任何建议/帮助

Answer 1

从 Flyway 8.2.1 开始，MySQL 和 MariaDB 数据库支持已成为单独依赖项的一部分，

flyway-mysql

。见https://flywaydb.org/documentation/database/mysql#java-usage

如果您在类路径中包含它，DatabaseTypeRegister 应该能够获得对 MariaDB 的支持。

Answer 2

对我有用的唯一方法是将这些依赖项添加到 build.gradle：

implementation 'org.flywaydb:flyway-core:8.4.4'
implementation 'org.flywaydb:flyway-mysql:8.4.4'

如图这里
