我的 spring-cloud-consul 演示没有注册到 consul 服务器

Question

我正在学习 spring 使用 consul 作为服务发现实现的云，我遵循了 Internet 上的教程。我正在使用 Eclipse 和 Maven。 pom文件由Spring Initializr生成。从 spring 官方文档中，他们说不再需要“@EnableDiscoveryClient”，所以我对其进行了评论，但是这个注释没有任何区别。

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领事服务器：

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

但是当我运行它作为 spring 启动应用程序时，它从未将我的服务注册到 consul，我错过了什么吗？

Answer 1

试图用您的 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 包含 Eureka 注册实现的依赖项。
