Spring Boot 应用程序在 Eureka 服务器中显示为 UNKNOWN

如何解决Spring Boot 应用程序在 Eureka 服务器中显示为 UNKNOWN

我正在使用 Spring 运行一个应用程序（作为 discovery Client 应用程序），还有一个带有 Eureka 的 discovery Server 和 Spring Cloud Config Server。当客户端应用程序启动时，它在 Eureka 中注册为“UNKNowN”，尽管其状态设置为“UP”，但无法从配置服务器获取属性。

客户端应用、Eureka 服务器和配置服务器 Spring Boot 版本：2.4.2

客户端 bootstrap.properties：

spring.application.name=config-client-app
spring.cloud.config.discovery.enabled=true
eureka.client.service-url.defaultZone=http://localhost:8761/eureka
eureka.instance.instance-id=${spring.application.name}

客户端 application.properties 文件：

logging.level.=debug
server.port=8900
eureka.client.healthcheck.enabled=true

客户端应用程序类：

@SpringBootApplication
@EnablediscoveryClient
@RestController
public class ConfigClientAppApplication {
    
    public static void main(String[] args) {
        SpringApplication.run(ConfigClientAppApplication.class,args);
    }
}

尤里卡服务器属性文件：

spring.application.name=discovery-server
server.port=8761
eureka.client.register-with-eureka=false
eureka.client.fetch-registry=false

尤里卡应用类：

@EnableEurekaServer
@SpringBootApplication
public class discoveryServerApplication {

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