1.新建SpringBoot项目 ,pom.xml文件  服务端依赖

<?xml version="1.0" encoding="UTF-8"?>
    <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 https://maven.apache.org/xsd/maven-4.0.0.xsd">
    	<modelVersion>4.0.0</modelVersion>
    	<parent>
    		<groupId>org.springframework.boot</groupId>
    		<artifactId>spring-boot-starter-parent</artifactId>
    		<version>2.2.4.RELEASE</version>
    		<relativePath/> 
    	</parent>
    	<groupId>com.zhang.cloud</groupId>
    	<artifactId>demo</artifactId>
    	<version>0.0.1-SNAPSHOT</version>
    	<name>demo</name>
    	<description>Demo project for Spring Boot</description>
    
    	<properties>
    		<java.version>1.8</java.version>
    		<spring-cloud.version>Hoxton.SR1</spring-cloud.version>
    	</properties>
    
    	<dependencies>
               
    		<dependency>
    			<groupId>org.springframework.cloud</groupId>
    			<artifactId>spring-cloud-starter-netflix-eureka-server</artifactId>
    		</dependency>
    	</dependencies>
    
    	<dependencyManagement>
    		<dependencies>
    			<dependency>
    				<groupId>org.springframework.cloud</groupId>
    				<artifactId>spring-cloud-dependencies</artifactId>
    				<version>${spring-cloud.version}</version>
    				<type>pom</type>
    				<scope>import</scope>
    			</dependency>
    		</dependencies>
    	</dependencyManagement>
    
    </project>

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

1.pom.xml文件 客户端依赖 web依赖

                </dependency>
            </dependencies>
        </dependencyManagement>
    </project>

2.启动类

@SpringBootApplication
    @EnableEurekaClient  //Eureka客户端注解
    public class EurekaClientApplication {
    	public static void main(String[] args) {
    		SpringApplication.run(EurekaClientApplication.class, args);
    	}
    }

3.配置文件 application.properties

#指定运行端口
    server.port=8101
    #服务名称
    spring.application.name=eureka-client
    #获取注册实例列表
    eureka.client.fetch-registry=true
    #注册到Eureka的注册中心
    eureka.client.register-with-eureka=true
    #配置注册中心地址
    eureka.client.service-url.defaultZone=http://localhost:8001/eureka/

4.启动项目,访问[http://localhost:8001/][http_localhost_8001]  ,可以看到已经注册到Eureka服务端
