Zuul + nacos 启动报错循环依赖问题The dependencies of some of the beans in the application context form a cycle

使用zuul作为网关，nacos作为注册中心，启动报错循环依赖问题。

The dependencies of some of the beans in the application context form a cycle:

   org.springframework.cloud.netflix.zuul.ZuulProxyAutoConfiguration (field private org.springframework.cloud.client.serviceregistry.Registration org.springframework.cloud.netflix.zuul.ZuulProxyAutoConfiguration.registration)
┌─────┐
|  nacosRegistration defined in class path resource [com/alibaba/cloud/nacos/registry/NacosServiceRegistryAutoConfiguration.class]
↑     ↓
|  nacosProperties (field private java.util.Optional com.alibaba.cloud.nacos.NacosDiscoveryProperties.nacosAutoServiceRegistrationOptional)
↑     ↓
|  nacosAutoServiceRegistration defined in class path resource [com/alibaba/cloud/nacos/registry/NacosServiceRegistryAutoConfiguration.class]
└─────┘

这里是由于springcloud版本问题，在nacos开源项目中也有人提出这个问题
https://github.com/alibaba/nacos/issues/3932

通过描述知道，这是spring cloud 2.2.2.RELEASE版本的问题，将版本改为2.2.5.RELEASE

重新启动，访问接口，成功！
