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.

我试着调试它，发现
FlywayAutoConfigurationIn.hasAtlastoneLocation（）
总是返回false，这意味着找不到位置（但
位置在调试器中看起来很正确），请参见以下屏幕截图：




感谢您的帮助：）
确保您没有意外创建名为db.migration的文件夹，而不是文件夹db/migration。


当您启用“压缩中间包”选项时，Intellij将在项目文件视图中以db.migration的形式显示两者。
尝试在Spring Boot
应用程序中使用。属性
：


spring.flyway.check-location = false


它将关闭Flyway迁移脚本并检查

另请参见Spring Boot的一组默认Flyway变量


这主要是因为复制粘贴。确保在创建文件夹结构后复制脚本，如下所示


resources/
        db/
          migration/
            _init.sql


IntelliJ将db.migration和db/migration显示为与db.migration相同。

您可以通过点击右上角的齿轮符号和扁平包装的勾号来查看实际结构。希望这能有所帮助。
我遇到了同样的问题，并帮助我在迁移文件夹中创建了新的空文件：


例如-init.sql
我已经准确地创建了db.migration文件夹，但是仍然出现了这个错误，但是我添加了这个错误，它看起来很有效

spring.flyway.check-location=false
不确定，但请尝试以下方法：检查我的答案希望它会有所帮助，这帮助了我：出现了这个问题。Ctrl+C和Ctrl+V可以创建一个名为
db.migration
的文件夹，而不是在IntelliJ 2019.3./src/main/resources/db/migration/+1中创建structur
db/migration
，这正是我键入
db.migration
作为新文件夹时遇到的问题。我强烈建议先创建
db
，然后再在其中创建
migration
文件夹。

resources/
        db/
          migration/
            _init.sql
