這篇文章主要介紹 spring cloud consul 組件玛荞，它是一個(gè)提供服務(wù)發(fā)現(xiàn)和配置的工具勋眯。consul具有分布式、高可用塞蹭、高擴(kuò)展性讶坯。
一、consul 簡(jiǎn)介
consul 具有以下性質(zhì)：
- 服務(wù)發(fā)現(xiàn)：consul通過(guò)http 方式注冊(cè)服務(wù)漱办，并且服務(wù)與服務(wù)之間相互感應(yīng)娩井。
- 服務(wù)健康監(jiān)測(cè)
- key/value 存儲(chǔ)
- 多數(shù)據(jù)中心
consul可運(yùn)行在mac windows linux 等機(jī)器上似袁。
二、consul安裝
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：

三扬霜、構(gòu)建工程
構(gòu)建一個(gè)consul-miya的springboot工程绒尊，導(dǎo)入依賴pring-cloud-starter-consul-discovery仔粥，其依賴文件：

在其入口文件ConsulMiyaApplication加入注解@EnableDiscoveryClient谭羔，開(kāi)啟服務(wù)發(fā)現(xiàn)：
@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服務(wù)的端口為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(dòng)工程瘟裸，訪問(wèn)localhost:8500,可以發(fā)現(xiàn)consul-miya被注冊(cè)了话告。
