配置修改

spring:
  application:
    name: spring-cloud-nacos-provider
  cloud:
    nacos:
      discovery:
        server-addr: localhost:8848

management:
  endpoints:
    web:
      exposure:
        include: '*'

代码实现

• 启动类

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

• controller （provider服务）

@RestController
public class ProviderController{

    @Value("${server.port}")
    private String serverPort;

    @GetMapping(value = "/provider/nacos/{id}")
    public String getPayment(@PathVariable("id") Integer id){
        return "nacos provider registry, server port: "+ serverPort+"\t id"+id;
    }
}
