SpringCloudAlibaba，nacos注册消费者通过服务名无法调用服务端

Question

nacos服务发现，但是写了一个消费端和服务端，消费端不能通过服务名访问到服务，总是报错，说 java.net.UnknownHostException: nacos-payment

消费端：配置没问题

80端口消费者 yml

server:
  port: 80
spring:
  application:
    name: nacos-order-80
  cloud:
    nacos:
      discovery:
        server-addr: localhost:8848
service-url:
  payment: http://nacos-payment

80端口启动类

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

80配置类

@Configuration
public class OrderConfig {
    @Bean
    @LoadBalanced
    public RestTemplate getRestTemplate(){
        return new RestTemplate();
    }
}

80控制类

@RestController
public class OrderController {

    @Value("${service-url.payment}")
    private String serviceable;

    @Autowired
    private RestTemplate restTemplate;

    @GetMapping(path = "/get")
    public String payment(){
        return restTemplate.getForObject(serviceable +"/nacos/get",String.class);
    }
}

9001端口服务端yml

server:
  port: 9001
spring:
  application:
    name: nacos-payment
  cloud:
    nacos:
      discovery:
        server-addr: localhost:8848
management:
  endpoints:
    web:
      exposure:
        include: '*'

9001端口的控制类启动类就不粘了

问题是这样的，配置如上，没有问题应该，服务也注册进去了但是，80端口请qiu服务失败

请大da帮 bang我，好不容易把微服务顶到 阿里巴巴这里了，结果碰到了一个想破脑袋也没ok的坑。

nacos作为注册中心，报错java.net.UnknownHostException: sc-provider - 远方斗牛士的个人空间 - OSCHINA - 中文开源技术交流社区
