一、consul 简介

consul 具有以下性质：

服务发现：consul通过http 方式注册服务，并且服务与服务之间相互感应。

服务健康监测

key/value 存储

多数据中心

consul可运行在mac windows linux 等机器上。Spring Cloud大型企业分布式微服务云架构源码请加一七九一七四三三八零

二、consul安装

linux

$ mkdir -p $GOPATH/src/github.com/hashicorp && cd $!
    $ git clone https:// github. com/ hashicorp/ consul.git
    $ cd consul
    $ make bootstrap
    $ make bootstrap

windows下安装：

见consul怎么在windows下安装

三、构建工程

构建一个consul-miya的springboot工程，导入依赖pring-cloud-starter-consul-discovery，其依赖文件：

<?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.forezp</groupId>
    	<artifactId>consul-miya</artifactId>
    	<version>0.0.1-SNAPSHOT</version>
    	<packaging>jar</packaging>
    
    	<name>consul-miya</name>
    	<description>Demo project for Spring Boot</description>
    
    	<parent>
    		<groupId>org.springframework.boot</groupId>
    		<artifactId>spring-boot-starter-parent</artifactId>
    		<version>1.5.2.RELEASE</version>
    		<relativePath/> 
    	</parent>
    
    	<properties>
    		<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    		<project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
    		<java.version>1.8</java.version>
    	</properties>
    
    	<dependencies>
    		<dependency>
    			<groupId>org.springframework.cloud</groupId>
    			<artifactId>spring-cloud-starter-consul-discovery</artifactId>
    		</dependency>
    		<dependency>
    			<groupId>org.springframework.boot</groupId>
    			<artifactId>spring-boot-starter-web</artifactId>
    		</dependency>
    
    		<dependency>
    			<groupId>org.springframework.boot</groupId>
    			<artifactId>spring-boot-starter-test</artifactId>
    			<scope>test</scope>
    		</dependency>
    	</dependencies>
    
    	<dependencyManagement>
    		<dependencies>
    			<dependency>
    				<groupId>org.springframework.cloud</groupId>
    				<artifactId>spring-cloud-dependencies</artifactId>
    				<version>Dalston.RELEASE</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>

在其入口文件ConsulMiyaApplication加入注解@EnableDiscoveryClient，开启服务发现：

@SpringBootApplication
    @EnableDiscoveryClient
    @RestController
    public class ConsulMiyaApplication {
    
    	@RequestMapping("/hi")
    	public String home() {
    		return "hi ,i'm miya";
    	}
    
    	public static void main(String[] args) {
    		new SpringApplicationBuilder(ConsulMiyaApplication.class).web(true).run(args);
    	}
    }

在其配置文件application.yml指定consul服务的端口为8500：

spring:
      cloud:
        consul:
          host: localhost
          port: 8500
          discovery:
            healthCheckPath: ${management.contextPath}/health
            healthCheckInterval: 15s
            instance-id: consul-miya
      application:
        name: consul-miya
    server:
      port: 8502

启动工程，访问localhost:8500,可以发现consul-miya被注册了。
