我使用eureka客户端和eureka服务器，但在启动eureka时收到错误“com.netflix.discovery.shared.transport.transportexception:无法在任何已知服务器上执行请求”。我没有和使用一个安全层的Eureka 。我的问题是“spring.cloud.version”。我读过这篇文章https://spring.io/blog/2020/12/15/spring-cloud-2020-0-0-rc1-aka-ilford-is-availablefor pom.xml的配置。
EUREKAA应用程序

@SpringBootApplication
@EnableEurekaServer
public class EurekaApplication {

   public static void main(String[] args) {
        SpringApplication.run(EurekaApplication.class, args);
   }

}
