这篇文章主要介绍 spring cloud consul 组件,它是一个提供服务发现和配置的工具。consul具有分布式、高可用、高扩展性。 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。 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 bootstrapwindows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/> <!-- lookup parent from repository --> </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>- 1

在其入口文件ConsulMiyaApplication加入注解@EnableDiscoveryClient,开启服务发现: @SpringBootApplication@EnableDiscoveryClient@RestControllerpublic 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-miyaserver: port: 8502启动工程,访问localhost:8500,可以发现consul-miya被注册了。 源码下载:
