配置文件

spring:application:name: platformcloud:nacos:server-addr: ip:portconfig:file-extension: ymlgroup: DEFAULT_GROUPprefix: ${sping.application.name}

启动类

@SpringBootApplication
// 这里必须有
@EnableFeignClients
public class PlatformApplication {public static void main(String[] args) {SpringApplication.run(PlatformApplication.class, args);}}

测试类 

@SpringBootApplication
@EnableFeignClients
@EnableCaching
@EnableScheduling
@EnableDiscoveryClient
@RefreshScope
public class PlatformApplication {public static void main(String[] args) {SpringApplication.run(PlatformApplication.class, args);}}

启动后就可以将服务注册到nacos中
