1. 下载安装nacos

2. 解压，运行

PS D:\path/to\nacos-server-2.4.3\nacos\bin> .\startup.cmd -m standalone

3. pom中引用：

        <!--服务注册 -->
        <dependency>
            <groupId>com.alibaba.cloud</groupId>
            <artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>
        </dependency>
        <!--服务调用feign -->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-openfeign</artifactId>
        </dependency>

4. yml中配置：

application.yml：

spring:
  application:
    name: service-sys
  profiles:
    active: dev
  cloud:
    nacos:
      discovery:
        server-addr: localhost:8848 # Nacos地址

5. main启动程序上加注释：

@EnableDiscoveryClient // 启用Nacos服务发现功能class, args

package com.atguigu.ssyx;

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

@SpringBootApplication
@EnableDiscoveryClient // 启用Nacos服务发现功能class, args
public class ServiceSysApplication {
    public static void main(String[] args) {
        SpringApplication.run(ServiceSysApplication.class, args);
    }
}
