新增配置application.yml

server:
  port: 8761
spring:
  application:
    name: smart-platform-eureka1
eureka:
  instance:
    hostname: localhost
  client:
    registerWithEureka: 
 
false
    fetchRegistry: false
    serviceUrl:
      defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka/
  server:
    #eureka服務自我保護模式 預設是開啟的
    enable-self-preservation: false
    #eureka服務 指定時間清理死掉的服務 預設60秒 單位毫秒
    eviction-interval-timer-in-ms: 60000

編寫eureka服務啟動類

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

@SpringBootApplication
@EnableEurekaServer
public class Application {
    public static void main( String[] args) throws Exception{
        new SpringApplicationBuilder(Application.class).run(args);
    }
}

效果展示（紅色提示語是因為application.yml配置中將服務自我保護模式設定為了false）
