springcloud eureka注册中心搭建

环境描述

① jdk1.8

② idea

③ springcloud版本 Finchley.SR2

④ maven3.0+

导入jar包

    <maven.compiler.source>1.8</maven.compiler.source>
    <maven.compiler.target>1.8</maven.compiler.target>

            </configuration>
        </plugin>
      </plugins>
    </pluginManagement>
  </build>

添加配置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服务自我保护模式 默认是开启的
    enable-self-preservation: false
    #eureka服务 指定时间清理死掉的服务 默认60秒 单位毫秒
    eviction-interval-timer-in-ms: 60000

编写eureka服务启动类

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（红色提示语是因为application.yml配置中将服务自我保护模式设置为了false）
