1，eclipse创建名为cloudsd的maven项目

pom文件如下:

<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">

src/main/resources下创建application.properties，内容如下：

server.port=8000
eureka.client.register-with-eureka=false
eureka.client.fetch-registry=false
#eureka.client.registerWithEureka=false
#eureka.client.fetchRegistry=false
eureka.client.serviceUrl.defaultZone=http://localhost:${server.port}/eureka/
security.basic.enabled=false

server.port=8000  配置端口为8000

eureka.client.register-with-eureka=false
eureka.client.fetch-registry=false

配置表明自己为eureka service而不是eureka client

eureka.client.registerWithEureka=false
eureka.client.fetchRegistry=false

同上配置一样（去掉）

eureka.client.serviceUrl.defaultZone  注册中心地址

创建启动类

package com.ldcn.cloudsd;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;

/**
 * Hello world!
 *
 */
@EnableEurekaServer
@SpringBootApplication
public class ServiceApplication 
{
    public static void main( String[] args ){
    	
    	 SpringApplication.run(ServiceApplication.class, args);
    }
}

@EnableEurekaServer  表明是eureka service

@SpringBootApplication  springboot应用

运行启动类ServiceApplication

访问localhost:8000 可以看到

服务注册中心创建完成，下面创建服务提供者(eureka client)

创建cloudsd.clientA的maven项目，pom同上

resources下创建application.properties，内容如下：

server.port=8010
eureka.client.serviceUrl.defaultZone=http://localhost:8000/eureka/
security.basic.enabled=false
spring.application.name=service-hi

eureka.client.serviceUrl.defaultZone 为上面服务注册中心地址

spring.application.name  为服务名称(非常重要，服务与服务之间调用需要用到)

创建clientA的application启动类

package com.ldcn.cloudsd;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.EnableEurekaClient;
/**
 * Hello world!
 *
 */
@EnableEurekaClient
@SpringBootApplication
public class ClientAApplication 
{
    public static void main( String[] args ){
    	
    	 SpringApplication.run(ClientAApplication.class, args);
    }
}

@EnableEurekaClient  表明为service client

运行clientA的application启动类

打开之前注册中心的地址:localhost:8000

可以看到

注册中心 出现了名为:SERVICE-HI的服务
