我正在尝试在Docker容器中运行项目测试。在本地运行时,所有测试都可以正常工作。当我尝试将测试移至Docker容器时开始出现错误。这是错误消息:
java.lang.IllegalStateException: Failed to load ApplicationContext [...] Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'flywayInitializer' defined in class path resource [org/springframework/boot/autoconfigure/flyway/FlywayAutoConfiguration$FlywayConfiguration.class]: Invocation of init method failed; nested exception is org.flywaydb.core.internal.command.DbMigrate$FlywayMigrateException:

从日志中我们可以看到已创建了容器映像,但是它无法迁移sql模式:

我不明白,最初能通过相同的测试,但是将它们移至docker容器时会失败?
看起来带有数据库的测试容器已经成功启动,所以没有问题,你得到的是一个空数据库。 然后你试着运行flyway,这失败了。spring boot中的Flyway在spring应用程序上下文初始化期间工作,因此实际迁移在应用程序上下文初始化时运行,因此迁移失败看起来像spring失败。 但是,记录的原因是:迁移文件有一个无效的内容:
SQL State : 42601 Error Code : 0 Message : ERROR: syntax error at or near "GENERATED" Position: 45 Location : db/migration/V1__initial_user.sql (/Users/villemossip/Desktop/GRP/GRP- SAS/application/build/resources/main/db/migration/V1__initial_user.sql) Line : 36 Statement : CREATE TABLE revinfo ( rev INTEGER GENERATED BY DEFAULT AS IDENTITY ( START WITH 1 ), revtstmp BIGINT, PRIMARY KEY (rev) ) GENERATED BY不支持此功能。
为什么?可能你的docker映像包含不支持此语法的RDBMS版本。因此,它与你在没有docker的本地环境中使用的数据库不同。
无论如何,这与docker,spring或flyway无关,而与DB和迁移代码有关。
在分辨率方面,我建议直接运行数据库的docker映像(不使用Java,testcontainers和flyway)。当它运行时,只需在pgadmin或其他程序中“手动”运行此迁移。你应该会看到相同的错误。
