我正在开发针对 MySQL 数据库的 Spring Data JPA 项目，并且我想从 Maven 运行端到端集成测试。
到目前为止，我已经配置为在阶段io.fabric8.docker-maven-plugin启动 MySQL 容器。pre-integration-test它将使用一个随机可用端口，我需要将其传递给我的application.properties文件。
我已经尝试使用 Maven 进行自动属性扩展，但我怀疑mysql.portmaven 属性只有在 spring 属性更新后才会得到解决。

应用程序属性
mysql.port = @mysql.port@
当我运行我的测试时，我得到一个连接错误，当我检查时target/classes/application.properties我发现它@mysql.port@没有更新。
任何建议将不胜感激。
