springCloud 整合nacos服务发现 服务注册成功但是feign服务发现时调用失败 同一套代码使用eureka进行feign调用正常

[Layfolk-zcy]

在nacos 的github上提交的问题 他们叫我来这找答案 菜鸟一枚请谅解

springBoot 2.6.3 spring-cloud-dependencies 2021.0.1 spring-cloud-alibaba-dependencies 2021.0.1.0

nacos服务端使用的是1.4.2 nacos控制台中服务已经注册成功

可能是Feign配置问题？方便提供一下Feign配置的代码嘛 具体Feign调用可以参考一下社区的Example具体配置 Example文档

可能是SkyWalking的问题，看日志最后一行

[Layfolk-zcy]

我刚刚尝试了下删除vm中配置的skywalking的配置还是服务发现报错 使用nacos官方jar单例模式启动 服务全部注册成功 nacos控制台可以看到 但是调用的时候还是一样的错误 consumer模块的所有依赖我都贴在了上面
