微服務的基本架構群組成，在本文以及接下來點所有文章中不做叙述，寫此文章的目的是為了搭建一個基本點微服務架構，注重實際操作。
建立maven工程
為了将示範用的所有工程統一管理，在此先建立一個父工程。
File -> New -> Project -> Maven
選擇jdk1.8，點選Next
填上GroupId和ArtifactId，點選Next
輸入合适的項目路徑，點選Finish
選擇This Window，則在目前視窗中打開項目，如下圖所示
使用spring boot建構eureka伺服器
- 在父工程上右擊，選擇New -> Module，點選Next，在ArtifactId輸入eureka-server後點選Next直到建立工程完成。
03.服務注冊中心Eureka -
修改pom檔案，添加依賴
在此隻需要添加spring boot的依賴即可，那麼該添加哪些依賴呢？
解壓生成的項目，打開pom.xml檔案即可發現我們需要的依賴。 03.服務注冊中心Eureka

添加配置檔案和啟動類
在eureka-server/src/main/resources中建立一個檔案application.yml，添加如下内容
server:
port: #端口号
spring:
application:
name: eureka-server #服務名稱
eureka:
client:
fetch-registry: false #是否檢索服務
register-with-eureka: false #是否注冊為服務
在eureka-server/src/main/java中建立package，命名為com.yyhe.example.eureka，并建立如下java類
package com.yyhe.example.eureka;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;
@SpringBootApplication
@EnableEurekaServer
public class EurekaServerApplication {
public static void main(String[] args) {
SpringApplication.run(EurekaServerApplication.class, args);
}
}
最後的項目結構如下：
運作EurekaServerApplication.java，通路http://localhost:9000/
到此，eureka server建立完成。
