我有一个带有几个实体类的Spring Boot应用程序,我正在尝试用Flyway实现数据库迁移。在启动时,似乎Spring Boot根本没有运行flyway。 这是我的应用程序.属性 这是我的建筑里的线.Gradle和flyway有关
我们正在尝试将迁移作为.sql文件置于版本控制之下。开发人员将编写一个vn__*.sql文件,提交到版本控制,并且每5分钟运行一次的作业将自动迁移到开发和测试数据库。一旦更改被证明没有引起问题,其他人就会运行一个手动作业来在生产上运行迁移。 我的问题: 我有一个演示迁移,创建了几个表。我将v4__demotable.sql检查到PC上的版本控制中。 阅读文档时,开发人员似乎建议我应该创建一个新的v
我刚刚在用户表中添加了一个新的时区列,现在我需要为所有现有记录填充它。 这些值应该根据同一表格中的另一列计算出来。 转换由名为OpenCage的地理服务完成。 所以我想创建一个新的Flyway迁移 读取表的每一行,获取其邮政编码值 调用地理服务的API并将邮政编码值传递给它 接收返回的时区, 并将其存储在时区列中 地理服务是我的应用程序中的SpringBoot,所以在迁移类中,我需要它。 而且我认
我是Spark的新手,我了解到转换发生在工作者身上,动作发生在驱动者身上,但是中间动作也可以发生在工作者身上(如果操作是可交换的和关联的),这给出了实际的并行性。 我查看了相关和协方差代码:https://github.com/apache/spark/blob/master/mllib/src/main/scala/org/apache/spark/mllib/stat/correlation/
正如标题所示,我正在寻找任何可以帮助我在Springs应用程序上下文(准确地说是持久性上下文)加载之前运行Flyway迁移的方法。原因是我在应用程序启动时运行的查询很少。这导致我的测试失败,因为正在对尚不存在的数据库表执行查询。我使用H2作为我的测试数据库。现在我只使用flyway核心依赖: 我有一个单一的Flyway配置类,如下所示: 并且属性在 我想实现的是:1.飞行路线做迁移2。Spring
在我的spring-boot项目中,我使用了Flyway的开箱即用集成(),并且有一些迁移脚本,它们在启动时执行,并通过默认的-table进行管理。 该项目还使用了一个自带flyway迁移脚本的模块,这些脚本是以编程方式迁移的,并在其他表中跟踪迁移情况。 由于主项目的迁移需要对通过模块迁移创建的一些表进行操作,因此模块迁移需要在flyway-plugin迁移主项目脚本之前进行。 如何在主要应用的F
