一切似乎都很好，但效果不佳。

拒绝连接问题如下

minikube service my-app-svc

Answer 1

您的服务或应用程序运行在不同的端口上，因为您的连接被拒绝。

Spring 在 9091 上启动运行 : Tomcat started on port(s): 9091 (http) with context path ''

但是您的服务正在重定向流量 TargetPort: 9001/TCP

你的目标端口应该是 9091 而不是 9001

您将通过节点端口 Ip 请求访问应用程序，该请求将到达 K8s 服务并转发到应用程序所在的 TargetPort: 9091/TCP。运行。
