无法在服务中启动 spring cloud eureka 客户端

Question

无法在服务中启动 spring cloud eureka 客户端

Aru*_*run 3 spring pom.xml spring-cloud spring-cloud-netflix

无法spring cloud eureka在服务中启动客户端。

我正在使用最新spring 2.1.1版本。

Discovery Server 以正确的方式启动，但不是服务客户端。

无法找出导致问题的原因.... 下面我有配置和详细日志。如果需要更多信息，请告诉我。

在应用程序类中，我使用了 @EnableDiscoveryClient

@SpringBootApplication
@EnableDiscoveryClient
public class TrackerServiceApplication {

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

}

在yml我给了server discovery URL.

spring:
  application:
    name: jtservice
eureka:
  client:
    service-url:
      defaultZone: http://localhost:8761/eureka
