consul实现微服务注册

创建父工程

创建父工程，用于版本管理，修改pom文件：设置打包类型为pom、设置依赖管理（src文件可以删除）

创建子项目

创建子项目依赖父工程，导入依赖

    
    
        org.springframework.cloud
        spring-cloud-starter-consul-discovery
    
    
    
        org.springframework.boot
        spring-boot-starter-web

        org.springframework.boot
        spring-boot-starter-test
        test
    
    
        cn.hutool
        hutool-all
        RELEASE
        test
    
    
        cn.hutool
        hutool-all
        RELEASE
        test
    

修改配置文件

server:
  port: 8004

spring:
  application:
    name: payment
  # consul注册中心地址
  cloud:
    consul:
      host: localhost
      port: 8500
      discovery:
        #hostname: 127.0.0.1
        service-name: ${spring.application.name}

主启动类添加@EnableDiscoveryClient注解

package com.yl.payment;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;

@SpringBootApplication
@EnableDiscoveryClient
public class Payment8004Application {

    public static void main(String[] args) {
        SpringApplication.run(Payment8004Application.class,args);
    }

}

本地启动consul，启动项目，浏览器访问：http://localhost:8500 可以看到服务payment成功注册到consul
