java - 无法启动 springboot-admin :java. lang.NoClassDefFoundError: org/springframework/cloud/netflix/zuul/ZuulServerAutoConfiguration

Question

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

SpringBoot版本:2.1.9.RELEASE

SpringCloud版本:Greenwich.SR3

SpringBootAdmin版本:2.1.5

我的主类代码:

@Configuration
@EnableAutoConfiguration
@EnableAdminServer
@EnableDiscoveryClient
public class SpringbootAdminApplication {

    public static void main(String[] args) {
        SpringApplication.run(SpringbootAdminApplication.class, args);
    }

}

我的maven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-->
<dependency>
            <groupId>de.codecentric</groupId>
            <artifactId>spring-boot-admin-starter-server</artifactId>
            <version>2.1.5</version>
        </dependency>

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

                <type>pom</type>
                <scope>import</scope>
            </dependency>

我的配置文件:

spring:
  application:
    name: spring-boot-admin
eureka:
  client:
    service-url:
      defaultZone: http://localhost:8010/eureka
server:
  port: 8083

我想启动应用程序

将 spring-cloud 依赖项移到 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>
