配置服务器无法配置数据源：未指定 'url' 属性，无法配置嵌入式数据源
Config-Server Failed to configure a DataSource: 'url' attribute is not specified and no embedded datasource could be configured
我正在尝试从包含所有应用程序属性的 github 存储库获取数据库配置。下图说明了我拥有的服务的结构：
当我访问我的配置服务器微服务时，一切正常，甚至当我在 post man 中测试它时，我也得到了配置。
The problem comes when i try to run the product service whilst
pointing to the config server microservice to get database
configurations. I get the error below:

问题出在配置服务器客户端的 porm 文件中，您需要添加 Spring Cloud starter Config 依赖项。在您的产品微服务中添加以下依赖项。
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-config</artifactId>
