我正在跟随一个设置eureka服务器的教程。我按照所有步骤操作，但当应该运行时却出现了以下错误导致程序崩溃:

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'org.springframework.cloud.netflix.eureka.server.EurekaServerInitializerConfiguration': Unsatisfied dependency expressed through field 'eurekaServerBootstrap'; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'eurekaServerBootstrap' defined in class path resource [org/springframework/cloud/netflix/eureka/server/EurekaServerAutoConfiguration.class]: Unsatisfied dependency expressed through method 'eurekaServerBootstrap' parameter 1; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'eurekaServerContext': Invocation of init method failed; nested exception is java.lang.IllegalStateException: java.lang.RuntimeException: Cannot Create new Replica Node :JerseyReplicationClient: http://localhost:8010/eureka/apps/:

我查找了可能的解决方案，包括清除Maven缓存，但这并没有起作用。

这是我在pom.xml中的依赖项：

<dependencies>
    <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-netflix-eureka-server</artifactId>
    </dependency>

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-test</artifactId>
        <scope>test</scope>
    </dependency>
</dependencies>

主类：

package com.photoapp.photoappdiscoveryservice;

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

@EnableEurekaServer
@SpringBootApplication
public class PhotoappdiscoveryserviceApplication {

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

application.properties:

server.port=8010

spring.application.name=discoveryservice

eureka.client.registerWithEureka=false
eureka.client.fetchRegistry=false
eureka.client.serviceUrl.defaultZone=http://localhost:8010/eureka

经过调查，我唯一能看到的原因是可能是一个错误的依赖关系。希望得到帮助以解决这个问题，谢谢！

- Oliver Darby

我从 https://start.spring.io/ 创建了一个项目，匹配了您的依赖项并复制了您的 application.properties 文件。它运行良好。 - Steephen

@Steephen谢谢，但如果它对你有效，你有任何想法为什么它对我没有用吗？ - Oliver Darby

@Steephen，我也刚尝试使用了该网站，但仍然遇到了相同的错误 - 感觉这可能是我的Maven出了问题？ - Oliver Darby

请您清空.m2仓库然后再试一次？ - prostý člověk

@ThangavelLoganathan 我终于解决了，虽然我不知道为什么，但我决定创建一个application.yml文件作为选项，并尝试以这种方式解决。这样做可以工作，但我不知道原因，而在application.properties中仍然存在问题。 - Oliver Darby

听起来很不错，但奇怪的是它不能与app.properties文件一起使用。 - prostý člověk

迄今为止，我发现最好的方法是创建一个application.yml文件，并通过以下方式添加属性：

应用程序.yml：

info:
  component: DiscoveryService

server:
  port: ${port:8010}


eureka:
  client:
    registerWithEureka: false
    fetchRegistry: false
  server:
    enable-self-preservation: false
    waitTimeInMsWhenSyncEmpty: 0
  instance:
    hostname: localhost
    lease-expiration-duration-in-seconds: 15
    lease-renewal-interval-in-seconds: 5

我不确定错误是什么，也不知道除了这种方式之外如何解决它。

编辑：我终于找到了解决方法，就是删除 pom.xml 文件中的客户端依赖项。由于某种原因，你不能同时在项目中使用两者，否则会出现 bean 错误。

- Oliver Darby

它对我起作用了，使用application.yml，谢谢。但即使在pom.xml中去掉客户端依赖项，仍无法使用application.properties。我不知道为什么！！！ - BOUTERBIAT Oualid

啊，我明白了，我猜他不喜欢我在application.properties中设置的：eureka.instance.prefer-ip-address=true。 - BOUTERBIAT Oualid

我在将版本更改为2.5.2后遇到了这个问题。为了解决这个问题，我必须将application.properties中的eureka.client.serviceUrl.defaultZone=http://localhost:8010/eureka更改为eureka.instance.hostname=localhost。

[供参考] 我的application.properties文件内容。

server.port=8010
spring.application.name=eureka-discovery-service
eureka.client.registerWithEureka=false
eureka.client.fetchRegistry=false
#eureka.client.serviceUrl.defaultZone= http://localhost:8010/eureka
eureka.instance.hostname=localhost
eureka.server.enable-self-preservation=true
eureka.server.waitTimeInMsWhenSyncEmpty=0
eureka.instance.lease-expiration-duration-in-seconds= 15
eureka.instance.lease-renewal-interval-in-seconds= 5

- Mainong

是的，你的解决方案有效。我也遇到了同样的问题。添加主机名部分后问题得到解决。 - Aditya Sawant

我在本地尝试复制并运行，遇到了相同的问题。

解决方案：

只需从application.properties中删除这两个属性即可。

eureka.client.serviceUrl.defaultZone=http://localhost:8010/eureka
eureka.instance.prefer-ip-address=true

并添加此属性

eureka.instance.hostname=localhost

它将会起作用！

- Shivansh Rajolia - HeLleR

这对我有用：只需添加此属性。

eureka.instance.hostname=localhost

我曾经遇到过同样的问题，然后我添加了以下依赖项：

    <dependency>
        <groupId>com.sun.jersey.contribs</groupId>
        <artifactId>jersey-apache-client4</artifactId>
        <version>1.19.1</version>
    </dependency

它对我有用。谢谢帮助

我也在跟着和您一样的教程学习，遇到了Eureka的同样问题。解决此问题有三种方法：

使用Mainong的解决方案，在application.properties中添加eureka.instance.hostname=localhost。
& 3）在相同的教程中，有一部分是关于解决这个问题的疑难解答。

您可以添加以下依赖项：

<dependency>
  <groupId>com.sun.jersey.contribs</groupId>
  <artifactId>jersey-apache-client4</artifactId>
  <version>1.19.4</version>
</dependency>

或删除eureka-client依赖项：

<dependency>
  <groupId>org.springframework.cloud</groupId>
  <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
</dependency>
