创建名称为“org.springframework.cloud.netflix.eureka.server.EurekaServerInitializerConfiguration”的bean时出错

问题描述 投票：0回答：12

我正在尝试运行一个非常基本的尤里卡服务器，但它给出了以下错误：

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 0; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'peerAwareInstanceRegistry' defined in class path resource [org/springframework/cloud/netflix/eureka/server/EurekaServerAutoConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [com.netflix.eureka.registry.PeerAwareInstanceRegistry]: Factory method 'peerAwareInstanceRegistry' threw exception; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'scopedTarget.eurekaClient' defined in class path resource [org/springframework/cloud/netflix/eureka/EurekaClientAutoConfiguration$RefreshableEurekaClientConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [com.netflix.discovery.EurekaClient]: Factory method 'eurekaClient' threw exception; nested exception is java.lang.RuntimeException: Failed to initialize DiscoveryClient!

@EnableEurekaServer

        SpringApplication.run(DemoApplication.class, args);
    }

}

添加了下面提到的依赖项并执行

mvn clean install
并重试

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

Add the below dependencies in the pom.xml along with the other required dependencies. It will work fine.

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

在pom.xml中添加依赖并解决

其实我在开发微服务结构时也面临着同样的问题

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

可以使用以下任一方法来解决问题

如果您将其用作服务器，请删除以下依赖项。

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

或

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>

我也遇到过同样的问题，也尝试了以上所有方法，但没有一个对我有用。

最后我观察到，我的STS版本是4.0，所以如果您使用STS 4.0或更高版本，您将一次又一次地面临这个问题。

请使用 STS 版本- 3.9.11 或任何其他 STS 版本 3。请勿使用版本 2 和 4。Netflix Eureka 与 STS 4.0 及更高版本存在兼容性问题。

STS 3.9.11 的下载链接是 --> https://github.com/spring-projects/toolsuite-distribution/wiki/Spring-Tool-Suite-3

希望这有帮助。

我有同样的问题，但弄清楚只是添加了错误的 eureka 服务器依赖项，正确的依赖项应该包含“starter”。

<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-**starter**-netflix-eureka-server</artifactId>
<version>2.0.2.RELEASE</version>

终于发现错误了！

它在 Spring Cloud 版本的“eureka”中的“server-config”和“zull”（如果您正在使用），全部必须在“Hoxton.SR10”、“Hoxton.SR11”或“Hoxton.SR12”之间.

是的，我都测试过

我的错误是：

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:

我的解决方案是删除 pom 中的 devtool 依赖项，以在作为服务运行时禁用实时重新加载 https://www.javatpoint.com/spring-boot-devtools#:~:text=DevTools%20stands%20for%20Developer%20Tool，更改%20和%20restart%20%20应用程序.

我最近也遇到了同样的问题。 就我而言，我必须保持以下步骤。

  1. eureka.client.enabled=false // 从 application.properties 文件中删除此行。
  2. 设置 server.port=8761 // 端口恰好为 8761;我尝试过端口8080，这会导致应用程序启动时出现异常
  3. 添加了 @Akshay Jain 提到的球衣依赖项
<dependency>
    <groupId>com.sun.jersey.contribs</groupId>
    <artifactId>jersey-apache-client4</artifactId>
    <version>1.19.4</version>
</dependency>
  1. 将 Spring Cloud 版本设置为 2020.0.0
    <properties>
        <spring-cloud.version>2020.0.0</spring-cloud.version>
    </properties>

最后，这解决了我的问题：

我将

spring-cloud-starter-netflix-eureka-client
的版本从
3.1.3
更新为
3.1.4

    <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
        <version>3.1.4</version>
    </dependency>

我有同样的问题，在我的 pom.xml 中 我更改为 2021.0.2 并且它运行没有错误。

<spring-cloud.version>2021.0.2</spring-cloud.version>
