Eureka（一）：服务搭建

Eureka是由Netflix开发的一款服务发现框架，简单来说就是类似zookeeper的注册中心
Eureka采用C-S架构，分为Eureka-client和Eureka-server，并且包含服务提供者和服务消费者两种角色

1、引入Eureka依赖

        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-eureka-server</artifactId>
            <version>3.1.0</version>
        </dependency>

2、新建启动类

package cn.badianboke.eukera;

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

@EnableEurekaServer
@SpringBootApplication
public class EurekaApplication {
    public static void main(String[] args) {
        SpringApplication.run(EurekaApplication.class, args);
    }
}
`

3、配置Eureka

server:
  port: 10086
spring:
  application:
    name: eurekaserver
eureka:
  client:
    service-url:
      defaultZone: http://127.0.0.1:10086/eureka
