springboot 配置 OpenFeign 时报错:Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request processing failed; Connection refused: no further information
报错内容如下:
2022-11-18 01:55:18.998 ERROR 22220 --- [nio-8086-exec-4] o.a.c.c.C.[.[.[/].[dispatcherServlet] : Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request processing failed; nested exception is feign.RetryableException: Connection refused: no further information executing GET http://127.0.0.1:8082/robotGroup/group/list] with root cause

。。。
在测试时忘记把另一个服务端启动,因为非springcloud项目,所以一直以为配置问题,检查发现另一个服务端没启动,启动之后执行正常。
