【问题描述】：

我正在使用PostgreSQL 为spring-boot 项目设置flyway 迁移，但无法连接数据库并出现异常。

未能执行目标 org.flywaydb:flyway-maven-plugin:6.0.8:migrate (default-cli) on project open-feign: org.flywaydb.core.api.FlywayException: Unable to connect to数据库。配置url、用户和密码！ -> [帮助 1]

Spring boot 版本： 2.2.1.RELEASE

Maven：

提前致谢

【问题讨论】：

您可以删除flyway插件以及flyway依赖的版本，然后您也可以删除flyway配置。 Spring Boot 将完成剩下的工作

@SimonMartinelli 感谢您的回复，我尝试了同样的错误。 org.flywaydb.core.api.FlywayException：无法连接到数据库。配置url、用户和密码！

你能发布堆栈跟踪吗？

【参考方案1】：

终于可以正常工作了，下面是我所做的更改。

根据 FlywayAutoConfiguration spring.flyway 期望例如

spring.flyway: 

无法读取如下属性

spring: 
    flyway: 
        user: ....
