java - Spring-Boot-Admin 服务器无法从 Eureka 注册中心注册客户端

Question

我刚刚从 Initializr 创建了一个新的 Spring-Boot-Admin 项目，并按照此处的说明进行操作：http: //codecentric.github.io/spring-boot-admin/2.0.0/

这是我的课：

@Configuration
@EnableAutoConfiguration
@EnableDiscoveryClient
@EnableAdminServer
public class ServiceAdminApplication {

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

这是我的属性文件：

eureka.instance.leaseRenewalIntervalInSeconds=10
eureka.instance.health-check-url-path=/actuator/health
eureka.client.registryFetchIntervalSeconds=5
eureka.client.serviceUrl.defaultZone=http://my.eureka.url:8580/eureka/

management.endpoints.web.exposure.include=*  
management.endpoint.health.show-details=ALWAYS

我有一个有效的 Eureka 注册表，其中注册了许多 Spring-Boot 应用程序。我知道这是可行的，因为他们能够找到彼此并通过 Eureka 注册表进行通信。

当我启动我的新 SBA 应用程序时，我可以看到它在 Eureka 注册表中注册了自己，所以它正在寻找 Eureka。但是，当我打开 SBA UI 时，它是空的，只是说“没有注册的应用程序”。在我的控制台上，我可以一遍又一遍地看到以下堆栈跟踪。
