我的spring-cloud-consul演示没有注册到consul服务器

我正在以 Consul 作为服务发现实现学习spring cloud，我在互联网上学习了一个教程 . 我正在使用eclipse和maven . pom文件由 Spring Initializr 生成 . 从 Spring 季官方文档来看，他们说"@EnableDiscoveryClient"不再需要了，所以我对此进行了评论，但这种说法没有任何区别 .

我的代码如下：

package org.codingfarm.ailurus;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@SpringBootApplication
//@CONFIGURATION
//@ENABLEAUTOCONFIGURATION
//@EnableDiscoveryClient
@RestController
public class AccountsApplication {

  @RequestMapping("/")
  public String home() {
    return "Hello World";
  }

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

}

maven pom：

我使用以下命令启动了一个consul服务器：

./consul agent -server -bootstrap-expect=1 -data-dir=/tmp/consul -ui -bind=127.0.0.1

但当我把它作为 Spring 季启动应用程序运行时，它只是从未将我的服务注册到 Consul ，我是否错过任何东西？

spring-boot consul spring-cloud-consul

    试图使用 pom.xml 启动应用程序 . 它失败并显示下一条消息：

    ***************************
APPLICATION FAILED TO START
***************************

Description:

Field registration in org.springframework.cloud.client.serviceregistry.ServiceRegistryAutoConfiguration$ServiceRegistryEndpointConfiguration required a single bean, but 2 were found:
    - eurekaRegistration: defined in BeanDefinition defined in class path resource [org/springframework/cloud/netflix/eureka/EurekaClientAutoConfiguration$RefreshableEurekaClientConfiguration.class]
    - consulRegistration: defined by method 'consulRegistration' in class path resource [org/springframework/cloud/consul/serviceregistry/ConsulAutoServiceRegistrationAutoConfiguration.class]

    您需要通过从 pom.xml 中删除依赖项来禁用Eureka发现客户端：

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

    因为它加载 spring-cloud-starter-netflix-eureka-client 依赖项，其中包含Eureka注册的实现 .
