## 一、新建cloud-zk-consumer-order80 ##

## 二、pom文件 ##

<dependencies>
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-web</artifactId>
            </dependency>
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-actuator</artifactId>
            </dependency>
            <dependency>
                <groupId>otc.orientsec</groupId>
                <artifactId>cloud-api-commons</artifactId>
                <version>1.0-SNAPSHOT</version>
            </dependency>
            <dependency>
                <groupId>org.projectlombok</groupId>
                <artifactId>lombok</artifactId>
                <optional>true</optional>
            </dependency>
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-starter-zookeeper-discovery</artifactId>
            </dependency>
        </dependencies>

## 三、application.yml文件 ##

server:
      port: 80
    
    spring:
      application:
        name: cloud-order-service
    
      cloud:
        zookeeper:
          connect-string: 127.0.0.1:2181,127.0.0.1:2182,127.0.0.1:2183

## 四、主启动类 ##

@SpringBootApplication
    @EnableDiscoveryClient
    public class ZkOrderMain80 {
        public static void main(String[] args)
        {
            SpringApplication.run(ZkOrderMain80.class,args);
        }
    }

注意一定要加上@EnableDiscoveryClient服务发现的注解

## 五、controller层 ##

controller层依赖RestTemplate负载均衡，如果忘记加@LoadBalanced注解，会报错500

@RestController
    @Slf4j
    public class ZkOrderController {
    
        private static final String PAYMENT_URL="http://cloud-payment-service";
    
        @Autowired
        private RestTemplate restTemplate;
    
        @GetMapping("/consumer/payment/zk")
        public String paymentZk()
        {
            log.info("收到请求");
            return restTemplate.getForObject(PAYMENT_URL+"/payment/zk",String.class);
        }
    }

## 六、测试 ##
