## 一、创建子module ##

cloudalibaba-consumer-nacos-order83

## 二、修改pom.xml ##

<dependencies>
         <dependency>
             <groupId>org.springframework.boot</groupId>
               <artifactId>spring-boot-starter-web</artifactId>
               <version>2.4.10</version>
          </dependency>
          <dependency>
              <groupId>org.springframework.boot</groupId>
              <artifactId>spring-boot-starter-actuator</artifactId>
              <version>2.4.10</version>
          </dependency>
          <dependency>
              <groupId>com.alibaba.cloud</groupId>
              <artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>
               <version>2021.1</version>
          </dependency>
          <dependency>
              <groupId>org.springframework.cloud</groupId>
              <artifactId>spring-cloud-loadbalancer</artifactId>
              <version>3.0.4</version>
          </dependency>
    </dependencies>

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。

## 三、修改application.yml ##

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

## 四、主启动类 ##

@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
