【问题讨论】：

Spring(boot) != JavaEE 9and JEE 是错误的缩写

我看到您正在使用 flyway 进行数据库架构升级。您是否创建了 src/main/resources/db/migration/ 目录？

是的，gyazo.com/f64d8ff42de1b51a20a0ecf36dda7748

@Kukeltje JavaEE 9 也是一个错误的缩写。

这应该是一个（（移位不起作用）和右括号，）丢失了。

【参考方案1】：

在 [classpath:db/migration] 中找不到迁移位置

添加适当的迁移，或者如果它们位于正确的位置，请检查它们的命名。

迁移的正确位置，即classpath:db/migration，是src\main\resources\db\migrations 文件夹。

正确的命名逻辑可以在here找到。

【讨论】：

好的，谢谢，这是我的后端部分，你有什么问题吗？ gyazo.com/a713cd331e84eab2c53c90737b091393

db.migration 只有一个包吗？应该是resources -> db -> migration

你是对的，它只是一个包裹！我把它分开了，现在我得到了这个：在类路径资源[org/springframework/boot/autoconfigure/flyway/FlywayAutoConfiguration$FlywayConfiguration.class]中定义的名称为'flywayInitializer'的bean创建错误：init方法的调用失败；嵌套异常是 java.lang.RuntimeException: Driver org.postgresql.Driver 声称不接受 jdbcUrl, jdbc:h2:mem:testdb;DB_CLOSE_DELAY=-1;DB_CLOSE_ON_EXIT=FALSE，这是我的 application.yml 文件：gyazo.com/7149648e598b69924d2904e9a3242428

你有 h2:mem 数据库，你告诉 Spring 它应该使用的驱动程序是 Postgresql？顺便说一句，如果对您的问题有帮助，点赞并接受答案总是很好的。

是的，我只是看不到我在哪里说过。我是这个论坛的新手，所以我的投票不会公开显示，哈哈

【参考方案2】：

错误日志描述“在 [classpath:db/migration] 中找不到迁移位置（请添加迁移或检查您的 Flyway 配置）”请显示有关 Flyway 配置的更多信息

【讨论】：

这不正确吗？ gyazo.com/f64d8ff42de1b51a20a0ecf36dda7748

【参考方案3】：

我假设您还没有任何 flyway 迁移，如果是这样，您现在可以从 gradle 或 maven 中删除 flyway 依赖项，它应该有助于启动应用程序。 如果您决定要进行迁移，则添加 flyway back，并在类路径中创建名为 db/migrations 的文件夹，并在其中添加迁移文件。

【讨论】：

没有足够的声望直接在帖子上发布图片，但是你去：gyazo.com/f64d8ff42de1b51a20a0ecf36dda7748

这看起来差不多。尝试将这些 flyway 设置也添加到 application.properties： spring.flyway.check-location=true # 是否启用 flyway。 spring.flyway.locked=false spring.flyway.encoding=UTF-8 #迁移脚本的位置。 spring.flyway.locations=classpath:db/migration spring.flyway.out-of-order=false # 更新模式 spring.flyway.schemas=your_schema spring.flyway.sql-migration-suffixes=.sql spring.flyway.sql -migration-prefix=spring.flyway.table=table_for_migration_tracking spring.flyway.validate-on-migrate=false
