无法启动 springboot-admin:java.lang.NoClassDefFoundError: org/sp

Question

当我尝试启动springboot-admin时，它会抛出：java.lang.NoClassDefFoundError： org/springframework/cloud/netflix/zuul/ZuulServerAutoConfiguration 是我的版本冲突吗？

春季启动版本：2.1.9.发布

春季云版本：格林威治.SR3

春季启动管理员版本：2.1.5

我的主要类代码：

@Configuration
@EnableAutoConfiguration
@EnableAdminServer
@EnableDiscoveryClient
public class SpringbootAdminApplication {
public static void main(String[] args) {
SpringApplication.run(SpringbootAdminApplication.class, args);
}
}

我的专家代码：

<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.1.9.RELEASE</version>
<relativePath/> <!-- lookup parent from repository -->
</parent>
<!-- It's partly dependent-->

将 spring-cloud 依赖项移动到 dependencyManagement 标记下，然后尝试，

<dependencyManagement>
<dependencies>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-dependencies</artifactId>
<version>Greenwich.SR3</version>
<type>pom</type>
<scope>import</scope>
</dependency>
</dependencies>
</dependencyManagement>
