<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"><modelVersion>4.0.0</modelVersion><parent><groupId>com.william</groupId><artifactId>springCloud_parent</artifactId><version>1.0-SNAPSHOT</version><relativePath/> <!-- lookup parent from repository --></parent><groupId>com.william</groupId><artifactId>eureka_server</artifactId><version>0.0.1-SNAPSHOT</version><name>eureka_server</name><description>Demo project for Spring Boot</description><properties><java.version>1.8</java.version><spring-cloud.version>Greenwich.SR1</spring-cloud.version></properties><dependencies><!--eureka注册中心的坐标--><dependency><groupId>org.springframework.cloud</groupId><artifactId>spring-cloud-starter-netflix-eureka-server</artifactId></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-test</artifactId><scope>test</scope></dependency></dependencies><build><plugins><plugin><groupId>org.springframework.boot</groupId><artifactId>spring-boot-maven-plugin</artifactId></plugin></plugins></build></project>

三、EurekaServerApplication

在这里插入图片描述

package com.william;import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;@SpringBootApplication
@EnableEurekaServer//开启Eureka注册中心
public class EurekaServerApplication {public static void main(String[] args) {SpringApplication.run(EurekaServerApplication.class, args);}}

四、application.yml

# 端口
server:port: 10086
spring:application:name: eureka-server # 应用名称，会在Eureka中作为服务的id标识（serviceId）
eureka:client:service-url: # EurekaServer的地址，现在是自己的地址，如果是集群，需要写其它Server的地址。defaultZone: http://127.0.0.1:10086/eureka#是否抓取服务列表fetch-registry: false#是否注册当前服务到注册中心register-with-eureka: false
