使用spring雲更改尤里卡服務器的默認端口

我得到了spring-boot應用程序，尤里卡服務器和尤里卡客戶端。使用spring雲更改尤里卡服務器的默認端口

這裏是我的服務器配置

server: 
    port: 8761 

spring: 
    application: 
    name: eureka-server

這裏是我的服務器代碼

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); 
    } 
}

下面是客戶端配置

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

這裏是我的客戶端代碼

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); 
    } 
}

以上工作完美，而服務器端口仍然是8761，但是當我嘗試更改它（8080或任何其他值）在服務器端口&客戶端defaultZone配置，服務器不斷拋出ConnectExceptions。

我該怎麼做？

當您使用新端口中的瀏覽器訪問eureka時會發生什麼？例如。 localhost：8080/ – alayor

您的評論幫助我解決了我的問題：我有eureka IHM，但只有尤里卡客戶端出現在註冊應用程序（而不是服務器）中。我在我的服務器配置中添加了'eureka.client.serviceUrl.defaultZone：「http：// localhost：8080/eureka」'，它工作正常！非常感謝你 –

嘗試此配置： 1.服務器。

server: 
    port: 8080 

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

2.客戶端。

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

是的，''eureka.client.serviceUrl.defaultZone'確實在服務器配置中丟失了，正如前面的評論所述。感謝您的幫助=） –
