Zookeper能當Dubbo的註冊中心，也能當SpringCloud的註冊中心。

2 環境準備

3 創建工程zk-provider

  application:
    name: zk-provider
  cloud:
    zookeeper:
      connect-string: 192.168.0.39:2181

(3) 主啓動類

/**
* @Description: EnableDiscoveryClient,用於向Zk和consul作爲註冊中心時註冊服務
* @Auther: zhurongsheng

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

(4) controller

@RestController
public class ZkProviderController {
    @Value("${server.port}")
    private String serverport;
    @RequestMapping("/zk")
    public String zk(){
        return "springcloud with zookeeper: "+serverport;
    }
}

  application:
    name: zk-customer
  cloud:
    zookeeper:
      connect-string: 192.168.0.39:2181

(3) 主啓動類

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

(4) 配置類

@Configuration
public class ApplicatrionConfig {

    @Bean
    @LoadBalanced
    public RestTemplate restTemplate(){
        return new RestTemplate();
    }
}

(5) Controller

@RestController
@RequestMapping("/zk")
public class ZookeeperController {
    public static final String PROVIDER_URL="http://zk-provider";
    @Autowired
    private RestTemplate restTemplate;
    @GetMapping("/customer")
    public String customer(){
        ResponseEntity<String> forEntity = restTemplate.getForEntity(PROVIDER_URL+"/zk", String.class);
        return forEntity.getBody();
    }
}
