没有人遇到这个错误吗！rabbitMQ连接上了，但发出actuator/bus-refresh时order报错。rabbitmq和docker都跟老师的版本一样了

关于配置不能实现自动刷新的说明

课程中自动刷新演示，我用的是SNAPSHOT版，这个版本的代码是可以变化的，你们拉取的代码和我演示时用的代码不一样了。

另外，spring的release版，自动刷新依旧有bug，课程最后升级部分从源码方面解释了这个bug。

大家看到这节内容，最后演示不成功，没有关系，继续往下看，springcloud组件相对独立，不影响对其它组件的学习。

  师兄，我也遇到此问题了，snapshot版本feign相关注解找不到，然后order我倒退用了之前的M3和M2版本，然后发起bus-refresh请求后就报这个错误，心态崩了

• 廖师兄 回复 小公举丶默 #2

  心态不用崩自动刷新那一块，有问题先放一边不影响后面的学习，最后升级到正式版再来看自动刷新问题。

order用的<spring-cloud.version>Finchley.M2</spring-cloud.version>是这个   会不会是这个cloud的问题呢！不用Finchley.BUILD-SNAPSHOT的原因是，用了这个版本Feign报错
