在我学习使用fegin和sentinel时，我使用了fegin的远程调用，也在controller层加了sentinel服务熔断和限流，但是我发现当我开启配置
feign:
sentinel:
enabled: true # 激活Sentinel对Feign的支持
时项目就会启动报错：

而当我去除那段配置时发现项目正常运行。我的配置写在openfegin的客户端中。sentinel的熔断也写在这里。请问有解决方法嘛？
经过我测试发现项目中没有使用Sentinel的降级和AOP，只是引入Sentinel的pom依赖，在开启了fegin对Sentinel的支持配置后，也会报相同的错误，这个配置主要是干嘛的？在不使用的时候，fegin的降级也是可以用的。
你这是有啥地方加了aop了嘛？
启动类加个服务注册与发现注解试试呢
