首先创建一个简单的mvn工程  
在pom.xml文件中引入依赖

<dependencies>
    		
    		<dependency>
    			<groupId>org.springframework.boot</groupId>
    			<artifactId>spring-boot-starter-parent</artifactId>
    			<version>2.0.1.RELEASE</version>
    			<type>pom</type>
    		</dependency>
    
    		
    		<dependency>
    			<groupId>org.springframework.cloud</groupId>
    			<artifactId>spring-cloud-dependencies</artifactId>
    			<version>Finchley.SR3</version>
    			<type>pom</type>
    		</dependency>
    
    		
    		
    		<dependency>
    			<groupId>org.springframework.cloud</groupId>
    			<artifactId>spring-cloud-starter-eureka-server</artifactId>
    			<version>1.4.6.RELEASE</version>
    		</dependency>

如果你的jdk比8高，可能会报错，把下面的依赖加上就好

<dependency>
    			<groupId>javax.xml.bind</groupId>
    			<artifactId>jaxb-api</artifactId>
    			<version>2.2.11</version>
    		</dependency>
    		<dependency>
    			<groupId>com.sun.xml.bind</groupId>
    			<artifactId>jaxb-core</artifactId>
    			<version>2.2.11</version>
    		</dependency>
    		<dependency>
    			<groupId>com.sun.xml.bind</groupId>
    			<artifactId>jaxb-impl</artifactId>
    			<version>2.2.11</version>
    		</dependency>
    		<dependency>
    			<groupId>javax.activation</groupId>
    			<artifactId>activation</artifactId>
    			<version>1.1.1</version>
    		</dependency>

然后配置一个application.yml

server:
      port: 8761
    spring:
       application:
          name: app-itmayiedu-order
      
    eureka:
      instance:
      ###注册中心ip地址
        hostname: 127.0.0.1
      client:
        serverUrl: 
          defaultZone: http://${eureka.instance.hostname}:8861/eureka/
        register-with-eureka:false
        fetch-registry: false

\#\#\#端口自选，一般默认是8761

最后创建一个启动的类

import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;
    
    @SpringBootApplication
    @EnableEurekaServer
    public class Eureka {
    public static void main(String[] args) {
    	SpringApplication.run(Eureka.class,args);
    }
    }

然后启动即可，在浏览器中输入localhost+端口号，返回如下界面即启动成功
