Question

我正在尝试在我的eureka发现服务器中注册spring-cloud配置服务器，但是我遇到此错误：

java.lang.IllegalStateException：找不到configserver（配置服务器）的实例

application.yml（配置服务器）：

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/

bootstrap.yml（尤里卡服务器）：

spring:
  application:
    name: eureka-server

server:
  port: 1111

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

bootstrap.yml（Eureka客户端）：

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

eureka-client.yml（在配置服务器存储库中找到的eureka-client配置）：


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

server:
  port: 8081

配置服务器本身的运行方式与运行时一样，它为eureka客户端获取配置。但是，每隔几分钟我会收到此错误，并且配置服务器本身从不注册：

从这个错误中，我也许错了，但是我感觉配置服务器有问题，但是我真的不确定是什么问题。请参阅上方的application.yml文件，以及下方的Application类和pom文件：

ConfigServerApplication：

@SpringBootApplication
@EnableDiscoveryClient
@EnableConfigServer
public class ConfigServerApplication {

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

}

用于ConfigServer的pom.xml：

如果任何人知道我在做什么错，那么任何帮助都会很棒。谢谢。

结论

我得出的结论是，当我在笔记本电脑上完成相同的项目并且项目运行得很好时，我的项目文件或计算机出现了问题。我不知道哪里出了问题

Answer 1

嘿，我的设置遇到了同样的问题。

我改变了 spring.application.name: config-server ..至 spring.application.name: configserver

问题消失了。我知道这很奇怪，但是它为我完成了工作。

Answer 2

有时（yaml / properties文件中不存在（spring.cloud.config.discovery.serviceId）此属性时，会出现此错误。我收到相同的“找不到配置服务器实例”错误。当我使用“ serviceId”时，它得到解决。

收到错误：java.lang.IllegalStateException：找不到configserver的实例（config-server）
