分手后的思念是犯贱 2022-10-01 12:41 99阅读 0赞

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 bootstrap
    复制代码

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">

            <artifactId>spring-boot-starter-parent</artifactId>
            <version>1.5.2.RELEASE</version>
            <relativePath/>

            </dependency>
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-web</artifactId>
            </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><br>
    复制代码

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);
        }
    }
    复制代码

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: 
    复制代码

启动工程，访问localhost:8500,可以发现consul-miya被注册了。 [java B2B2C Springcloud电子商城系统][java B2B2C Springcloud]
