Could not locate PropertySource: I/O error on GET request for "http://localhost:8761/config/diviso/dev/master": Connection refused: connect; nested exception is java.net.ConnectException: Connection refused

此警告消息意味着您的应用程序无法连接到其 Spring Cloud 配置服务器：JHipster Registry。

在开发配置文件中，这只是一个您可以忽略的警告，因为您的应用程序可以使用本地应用程序属性在sc/main/resources/config.

在prod配置文件中，这将是一个错误，您的应用程序将无法启动。注册表必须在您的应用程序之前启动，因为这是您的应用程序从中获取其应用程序属性并将自己注册为 Eureka 客户端的地方。

所以在开发中，你可以忽略这个警告，或者如果它让你烦恼，你可以启动一个注册表。

如果您的应用程序是单体应用程序而不是微服务应用程序，您可以选择退出发现客户端问题，如果您不需要水平扩展，部署会更简单。

尽管我之前已经生成并修改了我的项目，但我也遇到了同样的问题。

如果您使用的是 MySql，请转到 phpMyAdmin 页面并输入您的凭据。为我工作。
