           <!--Eureka server端依赖-->

  2.启动类
@SpringBootApplication
@EnableEurekaServer  //服务端Eureka注解
public class DemoApplication {
    public static void main(String[] args) {
        SpringApplication.run(DemoApplication.class, args);
    }
}
3.配置文件 application.properties
#指定运行端口
server.port=8001
#指定服务名称
spring.application.name=eureka-server
#指定主机地址
eureka.instance.hostname=localhost
#指定是否要从注册中心获取服务（注册中心不需要开启）
eureka.client.fetch-registry=false
#指定是否要注册到注册中心（注册中心不需要开启）
eureka.client.register-with-eureka=false
#关闭保护模式
eureka.server.enable-self-preservation=false
4.启动项目访问  [http://localhost:8001/][http_localhost_8001]   如图访问成功
