Question

我正在学习春季安全性，并试图运行该项目，但是它给了我一个错误。

我不知道该怎么办。这是我关注的Github link，Youtube视频[link]（https://www.youtube.com/watch?v=1N-xwmoN83w）。

当我尝试运行客户端应用程序时，它运行良好，但是当我尝试运行资源服务器时，它却没有运行，这给了我错误：

无法使用提供的发行人“ http://localhost:8090/uaa/oauth/token”来解析OpenID配置

GET请求“ http://localhost:8090/uaa/oauth/token/.well-known/openid-configuration”的I / O错误：   连接被拒绝：连接;嵌套异常为   java.net.ConnectException：连接被拒绝：connect

堆栈跟踪如下：

请帮助我解决这个错误，我是Spring Security的新手。

似乎某个应用程序应该在端口8090上运行，而实际上并没有（这是I / O错误的来源）。

您可以检查计算机上的此端口上是否有任何内容？如果此端口上正在运行某些应用程序，则该应用程序将使用404或类似内容进行响应。也许该应用在启动时崩溃了，而您没有看到它？
