Java springcloud B2B2C o2o多用戶商城 springcloud架構--服務註冊(consul)

1、consul 簡介

consul 具備如下性質：

服務發現：consul經過http 方式註冊服務，而且服務與服務之間相互感應。

服務健康監測

key/value 存儲

多數據中心

consul可運行在mac windows linux 等機器上。

2、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：

見consul怎麼在windows下安裝

3、構建工程

構建一個consul-miya的springboot工程，導入依賴pring-cloud-starter-consul-discovery，其依賴文件：

<?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"

</project>

在其入口文件ConsulMiyaApplication加入註解@EnableDiscoveryClient，開啓服務發現：

@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);
	}
}

在其配置文件application.yml指定consul服務的端口爲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

啓動工程，訪問localhost: 8500,能夠發現consul-miya被註冊了。
