如何通过 Spring Cloud Config for Postgresql 10.1 配置 Spring 数据（Spring 数据）？
How to configure Spring Data via Spring Cloud Config for Postgresql 10.1 (Spring Data)?
我已成功设置 Eureka 和 Spring Cloud Config 服务器，我的其他微服务已成功从中读取配置。
使用 Spring 数据和 Postgres 数据库的微服务问题。
我收到此错误：

如果 none 上述工作，最后一件事总是有帮助的是 -->
删除您的 .m2 存储库，然后全新安装您的项目。
