使用 spring-cloud-starter-netflix-eureka-client 依赖项在 pom.xml 中出现错误

Question

我正在开发需要通过 eureka 服务器与服务注册中心交互的微服务。但我在 pom.xml 中收到以下错误。在 maven 外部库的项目结构中，spring-cloud 依赖项不存在，我无法在主类中使用 @EnableEurekaClient 注释。 错误是

没有找到依赖 org.springframework.cloud:spring-cloud-starter-netflix-eureka-client:${project.version}

我的 pom.xml 是

这个 pom.xml 我是从 spring 初始化器生成的

Answer 1

在 pom.xml 中添加如下版本标签，即可解决问题。

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
    <version>3.0.3</version>
</dependency>
