According to MySQL 5.5.45+, 5.6.26+ and 5.7.6+ requirements SSL connection must be established by default if explicit option isn't set. For compliance with existing applications not using SSL the verifyServerCertificate property is set to 'false'. You need either to explicitly disable SSL by setting useSSL=false, or set useSSL=true and provide truststore for server certificate verification.

我在db / migration下有一个初始化sql，名称为：V1.0.0__init.sql（其中只有一行：use mydb;）

我在yml中的飞行路线配置（忽略其他数据源）：

spring:
  flyway:
    baseline-on-migrate: true
    locations: classpath:db/migration

我尝试对其进行调试，发现FlywayAutoConfiguratioin.hasAtLeastOneLocation()始终返回false，这意味着未找到位置（但是location在调试器中看起来很正确），请参见以下屏幕截图：

感谢任何帮助：）

Answer 1

请确保您没有意外地创建了一个名为db.migration的文件夹，而不是db / migration文件夹。
启用选项“紧凑中间包”后，Intellij将在项目文件视图中同时显示为db.migration。

Answer 2

大多数情况是由于复制粘贴而发生的。确保在创建如下所示的文件夹结构后复制脚本

resources/
        db/
          migration/
            _init.sql

IntelliJ将db.migration和db / migration显示为与db.migration相同。您可以通过单击右上方的齿轮符号和扁平化包装的勾号来实现实际结构。希望这会有所帮助。

Answer 3

我遇到了同样的问题，帮助我在迁移文件夹中创建了新的空文件：

例如 - init.sql

Answer 4

尝试在Spring Boot application.properties中使用：

spring.flyway.check-location = false

它会关闭Flyway迁移脚本并提供检查。

另请参阅Spring Boot的一组默认Flyway变量

https://docs.spring.io/spring-boot/docs/current/reference/html/common-application-properties.html

Answer 5

我已经完全创建了 db.migration 文件夹，但仍然出现此错误，但是我添加了它，看起来它起作用了 spring.flyway.check-location = false

Flyway：在以下位置找不到迁移位置：[classpath：db / migration]
