這篇文章主要介紹 spring cloud consul 元件,它是一個提供服務發現和配置的工具。 consul具有分散式、高可用、高擴展性。
consul 具有以下性質:
服務發現:consul透過http 方式註冊服務,並且服務與服務之間相互感應。
服務健康監測
key/value 儲存
多重資料中心
consul可運作在mac windows linux 等機器上。
linux
$ mkdir -p $GOPATH/src/github.com/hashicorp && cd $! $ git clone https://github.com/hashicorp/consul.git $ cd consul $ make bootstrap $ make bootstrap
windows下安裝:

建構一個consul-miya的springboot工程,導入依賴pring-cloud-starter-consul-discovery,其依賴檔案:
<?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>
在其入口檔案ConsulMiyaApplication加入註解@EnableDiscoveryClient,開啟服務發現:
@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); } }
在其設定檔application.yml指定consul服務的連接埠為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
啟動工程,存取localhost:8500,可以發現consul-miya被註冊了。
以上是SpringCloud教程之服務註冊(consul)的詳細內容。更多資訊請關注PHP中文網其他相關文章!
