1、搭建服务注册的服务端;
2、将Spring boot的一个项目做为服务注册进去；
一、搭建服务注册的服务端
1、首先通过IntelliJ IDEA或其它IDE创建一个spring boot 项目；
2、在pom.xml文件中添加spring cloud的版本依赖和Eureka的服务端依赖，具体代码如下：
<?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 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>com.lyq.demo</groupId>
<artifactId>eureka-server</artifactId>
<version>0.0.1-SNAPSHOT</version>
<packaging>jar</packaging>

</parent>

<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>
</plugins>
</build>
</project>
3、通过注解@EnableEurekaServer启动此为一个服务注册中心提供给其它应用进行对话，具体代码如下：
package com.lyq.demo;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;
/**
* 通过@EnableEurekaServer开启此端为服务注册中心
*/
@SpringBootApplication
@EnableEurekaServer
public class EurekaServerApplication {
public static void main(String[] args) {
SpringApplication.run(EurekaServerApplication.class, args);
}
}4、在application.yml或者application.properties(格式自己去做对应的改变)文件中进行注册服务端的参数配置：
#配置端口
server:
port: 1111
#配置为Eureka的服务端-服务注册中心
eureka:
instance:
hostname: localhost
client:
#因为自己是注册中心，设置为false，表示不向注册中心注册自己
register-with-eureka: false
#因为自己是注册中心，设置为false，表示不需要去检索服务
fetch-registry: false
#Eureka客户端将要注册的注册中心的地址
serviceUrl:
defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka/
5、编译运行项目即可，在浏览器输入: http://localhost:1111出现Eureka信息面板
二、将Spring boot的一个项目做为服务注册进去
1、创建一个springboot项目eureka-clientone;
2、在pom.xml引入springcloud的依赖还有eureka-client的依赖，具体如下：
<?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 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>com.lyq.demo</groupId>
<artifactId>eureka-clientone</artifactId>
<version>0.0.1-SNAPSHOT</version>
<packaging>jar</packaging>
<name>eureka-clientone</name>

</dependency>

</dependency>
</dependencies>
<!-- spring-cloud版本依赖 -->

<artifactId>spring-cloud-dependencies</artifactId>
<version>Dalston.SR1</version>
<type>pom</type>
<scope>import</scope>
</dependency>
</dependencies>
</dependencyManagement>
<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>
</plugins>
</build>
</project>
3、通过注解@EnableEurekaClient开启注册功能，激活Eureka的DiscoveryClient实现，具体代码如下：
package com.lyq.demo;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.EnableEurekaClient;
/**
* 使用注解@EnableEurekaClient开启注册功能，激活Eureka的DiscoveryClient实现
* @author : lyq
* @date : 2018/1/9
*/
@SpringBootApplication
@EnableEurekaClient
public class EurekaClientoneApplication {
public static void main(String[] args) {
SpringApplication.run(EurekaClientoneApplication.class, args);
}
}
4、在application.yml或者application.properties(格式自己去做对应的改变)文件中进行注册服务端的参数配置：
# 配置注册到注册中心的服务名称
spring:
application:
name: hello-service
# 配置服务注册中心的地址
eureka:
client:
serviceUrl:
defaultZone: http://localhost:1111/eureka/5、如果需要打印请求的日志，在HelloController里面注解DiscoveryClient对象来获取信息打印，具体如下：
package com.lyq.demo.controller;
import org.apache.log4j.Logger;
import org.omg.PortableInterceptor.SYSTEM_EXCEPTION;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.cloud.client.ServiceInstance;
import org.springframework.cloud.client.discovery.DiscoveryClient;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
/**
* @author : lyq
* @date : 2018/1/9
*/
@RestController
public class HelloController {
private final Logger logger = Logger.getLogger(HelloController.class);
@Autowired
private DiscoveryClient discoveryClient;
@GetMapping("hello")
public String hello() {
ServiceInstance instance = discoveryClient.getLocalServiceInstance();
System.out.println("********************************************");
System.out.println("* request path: "+instance.getUri() + " host: "+instance.getHost()+" serviceid: "+instance.getServiceId());
System.out.println("********************************************");
return "Eureka-clientone";
}
}
6、先运行服务端，然后在运行此需要注册的客户端在控制台可以见到如下注册信息：
7、或者在浏览器输入:http://localhost:1111也可以看到注册信息
