Spring Cloudを使用してEurekaサーバーのデフォルトポートを変更する

私は、スプリングブートアプリケーション、eurekaサーバー、およびeurekaクライアントを取得しました。

これが私のサーバー設定です

server:
  port: 8761

spring:
  application:
    name: eureka-server

これが私のサーバーコードです

package fr.maif.eurekaserver;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;
import org.springframework.cloud.netflix.zuul.EnableZuulProxy;

@SpringBootApplication
@EnableEurekaServer
@EnableZuulProxy
public class EurekaServerApplication {

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

これがクライアント構成です

spring:
  application:
    name: eureka-client
server:
  port: 8083
eureka:
  client:
    serviceUrl:
      defaultZone: "http://localhost:8761/eureka"

これが私のクライアントコードです

package fr.maif.eurekaclient;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;

@SpringBootApplication
@EnableDiscoveryClient
public class EurekaClientApplication {

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

上記は完全に機能し、サーバーポートは8761のままですが、サーバーポートとクライアントのdefaultZone構成の両方で（8080またはその他の値に）変更しようとすると、サーバーは継続的にConnectExceptionsをスローします。

何が悪いのでしょうか？

次の構成を試してください。1.サーバー。

server:
  port: 8080

eureka:
  instance:
   hostname: localhost
client:
  registerWithEureka: false
  fetchRegistry: false
  serviceUrl:
  defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka/

2.クライアント。

spring:
  application:
  name: eureka-client
server:
  port: 8083
eureka:
  client:
  registerWithEureka: true
  fetchRegistry: true
  serviceUrl:
    defaultZone: http://localhost:8080/eureka/
