1建工程cloud-consumer-zookeeper-order80

2pom与cloud-privider-payment工程一致

application.yml:

server:
  port: 80
# 服务别名，注册zookeeper到注册中心名称
spring:
  application:
    name: cloud-consumer-order
  cloud:
    zookeeper:
      connect-string: 192.168.53.179:2181

主启动类：

@SpringBootApplication
@EnableDiscoveryClient
public class OrderMain80 {
    public static void main(String[] args) {
        SpringApplication.run(OrderMain80.class, args);
    }
}

ApplicationConfig:

@Configuration
public class ApplicationConfig {
    @Bean
    @LoadBalanced //这个注解如果没有则会报错：I/O error on GET request for "http://cloud-provider-payment/payment/zk": cloud-provider-payment; nes
    public RestTemplate getRestTemplate() {
        return new RestTemplate();
    }
}

Controller:

@RestController
@Slf4j
public class OrderController {
    @Resource
    private RestTemplate restTemplate;
    private static final String url = "http://cloud-provider-payment";

    @GetMapping(value="/consumer/payment/zk")
    public String getPaymentInfo() {
        String result = restTemplate.getForObject(url + "/payment/zk", String.class);
        return result;
    }
}

 

2.测试注册进zookeeper:

 

 3.测试程序访问成功：
