首先創springboot專案  eureka方

pom.xml程式碼

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

</project>
 

application.yml

eureka:
  client:
    service-url:
    #註冊自身埠必須和註冊的專案統一
      defaultZone: http://localhost:8761/eureka/
    #不註冊自身
    register-with-eureka: false
    #開發環境關閉這種模式 生成環境需要開啟
  server:
    enable-self-preservation: false
#這是專案別名  因為註冊springcloud  上面不寫的話知道註冊的是哪個專案
spring:
  application:
    name: hlvyeureka
#設定埠
server:
  port: 8761
 

啟動類：

package com.hlvy.hlvyeureka;

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

@SpringBootApplication
@EnableEurekaServer//springcloud註解
public class HlvyeurekaApplication {

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

然後再建立一個springboot專案  client方

步驟和上面一樣但是這個地方選項不一樣

</project>

application.yml

eureka:
  client:
    service-url:
    #註冊自身埠必須和註冊的專案統一
      defaultZone: http://localhost:8761/eureka/
   #自定義註冊中心連結點進去名字
 # instance:
  #  hostname: hlvyclientName
#這是專案別名  因為註冊springcloud  上面不寫的話知道註冊的是哪個專案
spring:
  application:
    name: hlvyclient
#設定埠
server:
  port: 8081

 啟動類:

package com.hlvy.hlvyeclient;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;

@SpringBootApplication
@EnableDiscoveryClient
public class HlvyeclientApplication {

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

接著先執行eureka 然後執行client

瀏覽器開啟  註冊成功
