Spring cloud第一步：Eureka server的搭建

其实很简单，步骤如下：
1.新建maven项目，在pom.xml添加EurekaServer的依赖（只列出主要部分）：

<properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
    <java.version>1.8</java.version>
    <spring-cloud.version>Finchley.M9</spring-cloud.version>
</properties>


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


<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>


2.在application.yml中添加配置：
server:
  port: 8761


eureka:
  instance:
    hostname: localhost
  client:
    registerWithEureka: false
    fetchRegistry: false
    serviceUrl:
      defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka/


3.启动入口main函数添加注解 @EnableEurekaServer


package com.czy.eurekatest;


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


@EnableEurekaServer
@SpringBootApplication
public class EurekatestApplication {


    public static void main(String[] args) {
        SpringApplication.run(EurekatestApplication.class, args);
    }
}

4.启动程序，成功后访问地址http://localhost:8761/，出现spring Eureka的首页则部署成功，如下图：
