java.lang.ClassNotFoundException:com.netflix.discovery.EurekaClientConfig [英] java.lang.ClassNotFoundException: com.netflix.discovery.EurekaClientConfig

问题描述

我正在使用Spring Cloud Eureka，并使用 Spring Initializr ( http://start.spring.io/).使用 Spring Boot 2.0.2.RELEASE 生成的POM用户 Eureka Finchley.RC2 .当我在主类中添加注释 @EnableEurekaServer 时，也使用 @SpringBootApplication 进行注释，然后使用以下命令启动服务器:

I'm using Spring Cloud Eureka and creating the project using Spring Initializr (http://start.spring.io/). The generated POM user Eureka Finchley.RC2 with Spring Boot 2.0.2.RELEASE. When I add the annotation @EnableEurekaServer in the main class, the one annotated with @SpringBootApplication also, and I start the server with following command:

mvn spring-boot:run

我收到例外

java.lang.ClassNotFoundException: com.netflix.discovery.EurekaClientConfig

以下是Initializr生成的pom.xml:

the following is the pom.xml generated by the Initializr:

推荐答案

正如"rosa lu"所说，启动尤里卡服务器时，我遇到以下类似问题:java.lang.NoClassDefFoundError:com/netflix/discovery/converters/XmlXStream
SpringBoot = 2.0.5.RELEASE
SpringCloud.version = Finchley.SR1
正如"rosa lu"所说，我将本地maven存储库更改为新路径，然后重建项目，然后解决问题
我希望我的回答可以对遇到同样问题的任何人有所帮助.

As 'rosa lu' said, when launch eureka server I have the similar issue as below: java.lang.NoClassDefFoundError:com/netflix/discovery/converters/XmlXStream
SpringBoot=2.0.5.RELEASE
SpringCloud.version=Finchley.SR1
As 'rosa lu' said, I change my local maven repository to a new path, and rebuild my project, then solve the problem
I hope my answer can help anyone who has the same issue .
