本文介绍了一个使用 Spring Boot 和 Spring Cloud 实现的微服务应用实例，该应用通过 Eureka 进行服务发现与注册。具体配置包括 application.yml 文件设置端口和服务别名，pom.xml 文件管理 Maven 依赖，并实现了一个简单的 RESTful API。

application.yml

##端口号
server:
  port: 8101

##服务别名
spring:
  application:
    name: app-guofeng-number
eureka:
  client:
    service-url:
      ##注册到指定的eureka注册中心
      defaultZone: http://localhost:8000/eureka
    ##单注册中心时为false 集群时为true
    register-with-eureka: true
    ##检索服务信息
    fetch-registry: true
