本篇內容主要講解“Spring cloud中怎么配置項目結構實現Eureka服務”，感興趣的朋友不妨來看看。本文介紹的方法操作簡單快捷，實用性強。下面就讓小編來帶大家學習“Spring cloud中怎么配置項目結構實現Eureka服務”吧!
首先，我們在創建投放系統之前，先看一下我們的工程結構：
mscx-ad-sponsor就是我們的廣告投放系統。如上結構，我們需要首先創建一個Parent Project mscx-ad
來編寫父項目的pom，來管理我們的統一依賴信息。

</project>Eureka Server (提供服務的注冊和發現)
Eureka Client
Service provider (服務提供方，將自身注冊到server上，從而讓Eureka Server保存provider的元數據，讓其他的服務消費者可以找到當前服務)
Service Consumer(服務消費方，從Eureka Server上獲取注冊的服務列表，從而消費服務)
創建project mscx-ad-discovery, 然后使用SpringBoot項目的三部曲（加依賴，加注解，改配置）

@EnableEurekaServer)@SpringBootApplication
@EnableEurekaServer
public class DiscoveryApplication {
public static void main(String[] args) {
SpringApplication.run(DiscoveryApplication.class, args);
}
}spring:
application:
name: ad-discovery-server
server:
port: 8888
eureka:
instance:
hostname: localhost #單機版
client:
fetch-registry: false #是否從eureka server獲取注冊信息
register-with-eureka: false #注冊自己到eureka
service-url:
defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka/測試的時候，需要修改hosts文件
zhangpandeMacBook-Pro:etc zhangpan$ cat hosts ## ... ## 127.0.0.1 localhost 127.0.0.1 server1 127.0.0.1 server2 127.0.0.1 server3 ::1 localhost
然后修改application.yml
spring: application: name: ad-discovery profiles: server1 server: port: 7777 eureka: instance: hostname: server1 prefer-ip-address: false client: service-url: defaultZone: http://server2:8888/eureka/,http://server3:9999/eureka/ --- spring: application: name: ad-discovery profiles: server2 server: port: 8888 eureka: instance: hostname: server2 prefer-ip-address: false client: service-url: defaultZone: http://server1:7777/eureka/,http://server3:9999/eureka/ --- spring: application: name: ad-discovery profiles: server3 server: port: 9999 eureka: instance: hostname: server3 prefer-ip-address: false client: service-url: defaultZone: http://server2:8888/eureka/,http://server1:7777/eureka/
啟動集群測試：
配置啟動profile / java -jar mscx-ad-discovery.jar --spring.profiles.active=server1 
效果展示
