1，首先，修改 pom.xml 文件，引入 Nacos Discovery Starter。

<dependency>
     <groupId>com.alibaba.cloud</groupId>
     <artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>
 </dependency>
<dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>com.alibaba.cloud</groupId>
                <artifactId>spring-cloud-alibaba-dependencies</artifactId>
                <version>2.1.0.RELEASE</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
        </dependencies>
</dependencyManagement>

2，在 /src/main/resources/application.yml 配置

spring:
  cloud:
    nacos:
      discovery:
        server-addr: 127.0.0.1:8848
  application:
    name: mall-coupon

3，启动类开启 @EnableDiscoveryClient 注解

@SpringBootApplication
 @EnableDiscoveryClient
 public class ProviderApplication {
  public static void main(String[] args) {
    SpringApplication.run(ProviderApplication.class, args);
  }
 }

4，运行项目，nacos 中心即可看到如下已注册服务
