# [Spring Cloud之DiscoveryClient使用][Spring Cloud_DiscoveryClient] #

主要修改zk order的代码：

package com.toov5.api.controller;
    
    import java.util.List;
    
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.beans.factory.annotation.Value;
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    import org.springframework.cloud.client.ServiceInstance;
    import org.springframework.cloud.client.discovery.DiscoveryClient;
    import org.springframework.cloud.client.discovery.EnableDiscoveryClient;
    import org.springframework.cloud.client.loadbalancer.LoadBalanced;
    import org.springframework.context.annotation.Bean;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RestController;
    import org.springframework.web.client.RestTemplate;
    
    @RestController
    @SpringBootApplication
    @EnableDiscoveryClient //如果服务使用consul或者zk使用这个注解 向注册中心注册服务
    public class zkOrderApiControllerRibbon {
        @Value("${server.port}")
        private String serverPort;
        @Autowired
        private RestTemplate restTemplate;
        @Autowired
        private DiscoveryClient discoveryClient;
        
        @RequestMapping("/orderToMember")
      public String orderToMember() {
            String url ="http://zk-member/getMember"; 
            return restTemplate.getForObject(url, String.class);
      }
        
        @RequestMapping("/discoveryMember")
        public List<ServiceInstance> discoveryMember() {
            List<ServiceInstance> instances = discoveryClient.getInstances("zk-member");
            for (ServiceInstance serviceInstance : instances) {
                System.out.println("url"+serviceInstance.getUri());
            }
            return instances;
        }
        
        public static void main(String[] args) {
            SpringApplication.run(zkOrderApiControllerRibbon.class, args);
        }
        @Bean
        @LoadBalanced
        RestTemplate restTemplate() {
            return new RestTemplate();
        }
    }

结果：
