配置此Discovery Server

Question

我一直在尝试使用spring boot和netflix oss来学习微服务开发。

我已经被这个eureka仪表板错误困住了两天了，我似乎无法解决它。请帮忙。我有一个发现客户端实例，服务器处于独立模式 This is how the dashboard looks like

这是服务器主类

package com.example;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;

@SpringBootApplication
@EnableEurekaServer

public class EurekaApplication {

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

conf files application.yml

server:
  port: 8761

eureka:
  instance:
    hostname: localhost
  client:
    registerWithEureka: false
    fetchRegistry: false
    serviceUrl:
     defaultZone: ${eureka.instance.hostname}:${server.port}/eureka/
    server:
      waitTimeInMsWhenSyncEmpty: 0

bootstrap.yml

spring:
  application:
    name: eureka

Answer 1

问题在于我的application.yml文件 serviceUrl属性值有一个错字。我忘了在eureka.instance.hostname

之前加入http：//

这是固定的yaml

eureka:
  instance:
    hostname: localhost
  client:
    registerWithEureka: false
    fetchRegistry: false
    serviceUrl:
     defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka/
    server:
      waitTimeInMsWhenSyncEmpty: 0

Brixton.RC1

从来都不是问题

无需添加spring-milestone作为依赖项，因为您正在使用发行版本。它仅在您使用M版本时使用。有关详细信息，请参阅spring boot官方文档。您的代码看起来很好。它应该工作。指定错误你得到了。这是我正在使用的pom.xml和.yml文件。：

配置此Discovery Server

尤里卡：例如： hostname：localhost 客户：＃不是客户，不要自己注册 registerWithEureka：false fetchRegistry：false

  server:
  port: 1111   # HTTP (Tomcat) port

# Discovery Server Dashboard uses FreeMarker.  Don't want Thymeleaf        templates
spring:
  thymeleaf:
    enabled: false     # Disable Thymeleaf
