Question

我刚开始使用jhipster。

我使用jhipster生成一个uaa应用程序，并在启动时遇到以下错误。

我使用命令＆＃34; yo jhipster＆＃34;生成了这个应用程序。并使用mvn命令运行它。

如果在Docker中运行

，您的注册表可能无法启动或无法访问您的服务

这条线告诉你错误是什么

Caused by: org.springframework.web.client.ResourceAccessException: I/O error on GET request for "http://localhost:8761/config/uaa/dev/master": Connection refused; nested exception is java.net.ConnectException: Connection refused

如果您在Docker容器中启动UAA，请确保您没有访问＆＃34; localhost＆＃34;，但是＆＃34; registry＆＃34;代替

最好的问候

GET请求的I / O错误＆＃34; http：// localhost：8761 / config / uaa / dev / master＆＃34;
