1 简介

Zookeper能当Dubbo的注册中心，也能当SpringCloud的注册中心。

2 环境准备

3 创建工程zk-provider

(1) pom

(2) application.yml

server:
  port: 7002
#服务名
spring:
  application:
    name: zk-provider
  cloud:
    zookeeper:
      connect-string: 192.168.0.39:2181

(3) 主启动类

/**
* @Description: EnableDiscoveryClient,用于向Zk和consul作为注册中心时注册服务
* @Auther: zhurongsheng
* @Date: 2020/3/10 23:36
*/
@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;
    }
}

(5) 启动主程序

3 创建服务消费者 zk-customer

    </dependency>
</dependencies>

(2) application.yml

server:
  port: 8001
#服务名
spring:
  application:
    name: zk-customer
  cloud:
    zookeeper:
      connect-string: 192.168.0.39:2181

(3) 主启动类

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

(4) 配置类

@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();
    }
}
