springcloud--服务发现服务

服务发现服务(microservice-eureka-server)
用户服务提供者(microservice-provider-user)
电影服务消费者(microservice-consumer-movie)

工具及软件

JDK：建议使用 JDK 1.8
Spring Boot：实验使用 Spring Boot 2.0.7.RELEASE 版本。
Spring Cloud：实验使用 Spring Cloud Finchley.SR2 版本。
Maven：实验使用 Maven 3.6.0 构建项目

Using platform encoding (UTF-8 actually) to copy filtered resources, i.e. build is platform dependent!

是不是idea的maven仓库和系统配置的maven仓库是不是不相同

server:
  port: 8080
eureka:
  instance:
    hostname: localhost
  client:
    registerWithEureka: false
    fetchRegistry: false
    serviceUrl:
      defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka/

registerWithEureka: 表示是否需要将自身也加入 Eureka Server 中，默认为 true。当前实例本身就是 Eureka Server，故设置为 false。
fetchRegistry：是否需要从其他 Eureka Server 获取注册信息，默认为 true。本次实验采用的是一个单点 Server，无需同步其他 Server 的注册信息，故设置为 false。
serviceUrl.defaultZone：当前 Eureka Server 的交互地址，多个地址可用 ',' 号隔开。
若有需要自定义配置，如搭建高可用的 Eureka Server，可查看官方文档：https://cloud.spring.io/spring-cloud-netflix/multi/multi_spring-cloud-eureka-server.html

配置文件

server:
  # 指定Tomcat端口
  port: 8000
spring:
  application:
    # 给这个服务取名叫做：microservice-provider-user

#management:

#      show-details: always

management:
  endpoints:
    web:
      exposure:
        include: '*'

    health:
      # 是否展示健康检查详情
      show-details: always

# 新增配置
eureka:
  client:
    serviceUrl:
      defaultZone: http://localhost:8080/eureka/
  instance:
    prefer-ip-address: true

简单介绍一下以上配置：

eureka.client.serviceUrl.defaultZone：表示 Eureka Server 的交互地址，此前已经在 Eureka Server 中配置该 defaultZone。
eureka.instance.prefer-ip-address：表示将自身服务器的 IP 地址注册到 Eureka Server 中。如果不配置或者设置为 false，则将会将服务器的 hostname 注册到 Eureka Server 中。
