获取错误：java.lang.IllegalStateException：未找到configserver（config-server）的实例

Question

spring:
  application:
    name: config-server
  cloud:
    config:
      server:
        git:
          uri:  https://github.com/danielturato/microservices-config.git
          username: *******
          password: *******
          clone-on-start: true

server:
  port: 8888

eureka:
  instance:
    hostname: localhost
    appname: config-server
  client:
    service-url:
      defaultZone: http://localhost:1111/eureka/

spring:
  application:
    name: eureka-server

server:
  port: 1111

eureka:
  client:
    registerWithEureka: false
    fetchRegistry: false
    service-url:
      defaultZone: http://localhost:1111/eureka/

spring:
  application:
    name: eureka-client
  cloud:
    config:
      discovery:
        enabled: true
        service-id: config-server

eureka:
  client:
    service-url:
      defaultZone: http://localhost:1111/eureka/

server:
  port: 8081

config服务器本身的工作方式是，当运行时，它为eureka客户端获取配置。但是,每隔几分钟,我就会收到这个错误,配置服务器本身从不注册：

java.lang.IllegalStateException: No instances found of configserver (config-server)

从这个错误中，我可能错了，但我觉得配置服务器有问题，但我真的不确定是什么问题。请参阅上面的Application.yml文件，下面的Application类&pom文件：

ConfigServerApplication：

@SpringBootApplication
@EnableDiscoveryClient
@EnableConfigServer
public class ConfigServerApplication {

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

}

我得出的结论是，要么是我的项目文件出了问题，要么是我的电脑出了问题，因为我在笔记本电脑上完成了一个相同的项目，项目运行完全正常。我也不知道出了什么问题

Answer 1

我的设置也有同样的问题。

我将spring.application.name:config-server...更改为spring.application.name:configserver

事情就这样不了了之了。我知道这是一个奇怪的，但它为我做了工作。
