          org.springframework.cloud
          spring-cloud-loadbalancer
          3.0.4
      

注意：nacos2021.1 版本不再集成ribbon，所以需要添加spring-cloud-loadbalancer依赖做负载均衡。

server:
  port: 83

spring:
  application:
    name: nacos-consumer-order
  cloud:
    nacos:
      discovery:
        server-addr: 127.0.0.1:8848

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

service-url:
  nacos-user-service: http://nacos-payment-provider

@SpringBootApplication
@EnableDiscoveryClient
public class NacosOrder83 {
    public static void main(String[] args)
    {
        SpringApplication.run(NacosOrder83.class,args);
    }
}

五、业务类

5.1 配置类RestTemplate做负载均衡

@Configuration
public class ConsumerConfig {

    @Bean
    @LoadBalanced
    public RestTemplate getRestTemplate()
    {

        return new RestTemplate();
    }
}

5.2 业务类controller

@RestController
public class NacosOrderController {

    @Value("${service-url.nacos-user-service}")
    private String serverURL;
    @Resource
    private RestTemplate restTemplate;

    @GetMapping("/consumer/nacos/{id}")
    public String getPayment(@PathVariable("id") Integer id)
    {
        return restTemplate.getForObject(serverURL+"/payment/nacos/"+id,String.class);
    }
}

六、测试
