java - 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/ ) 创建项目。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时，也使用注释的那个，我使用以下命令启动服务器：@EnableEurekaServer@SpringBootApplication

mvn spring-boot:run

我收到异常

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

以下是 Initializr 生成的 pom.xml：

解决方案

我发现本地maven仓库中的eureka-clien-1.9.2.jar是零长度文件，所以我删除它并重新下载依赖，一切正常！
