微服务SpringCloud开弓之Zookeeper服务注册与发现《四》

目录

      • SpringCloud整合Zookeeper替代Eureka
        • 1、注册中心Zookeeper
        • 2、服务提供者
        • 3、服务消费者

Eureka停止更新了

地址

SpringCloud整合Zookeeper替代Eureka

1、注册中心Zookeeper

  • 关闭Linux服务器防火墙后启动Zookeeper服务器

    //临时关闭
    service iptables stop
    //禁止开机启动
    chkconfig iptables off
    
  • Zookeeper服务器取代Eureka服务器,zk作为服务注册中心

2、服务提供者

1、新建cloud-provider-payment8004

2、POM


spring-cloud-starter-zookeeper-discovery

3、YML

server:
  # 8004表示注册到zookeeper服务器的支付服务提供者端口号
  port: 8004
spring:
  application:
    # 服务别名---注册zookeeper到注册中心的名称
    name: cloud-provider-payment
  cloud:
    zookeeper:
      # 默认localhost:2181
      connect-string: localhost:2181

4、主启动类

@SpringBootApplication
@EnableDiscoveryClient
public class PaymentMain8004 {
    public static void main(String[] args) {
        SpringApplication.run(PaymentMain8004.class,args);
    }
}

5、Controller

@RestController
@Slf4j
public class PaymentController {

    @Value("${server.port}")
    private  String   serverPort;

    @RequestMapping(value = "payment/zk")
    public String paymentZk() {
        return "SpringCloud with zookeeper:" + serverPort + "\t" + UUID.randomUUID().toString();
    }
}

6、启动8004注册进zookeeper zkServer.sh start

  • 报错

  • 原因

解决zookeeper版本jar包冲突问题

  • 重新弄Pom文件

服务节点是临时节点

3、服务消费者

  • 新建cloud-consumerzk-order80

  • POM

          connect-string: 192.168.149.103:2181
    
  • 主启动

    @SpringBootApplication
    @EnableDiscoveryClient
    public class OrderZkMain80 {
        public static void main(String[] args) {
            SpringApplication.run(OrderZkMain80.class, args);
        }
    }
    
  • 业务类

    1、配置been

    @Configuration
    public class ApplicationContextConfig {
        @Bean
        @LoadBalanced
        public RestTemplate getRestTemplate() {
            return new RestTemplate();
        }
    }
    

    2、controller

    @RestController
    @Slf4j
    public class OrderZkController {
        public static final String INVOKE_URL = "http://cloud-provider-payment";
        @Resource
        private RestTemplate restTemplate;
        /**
         * http://localhost/consumer/payment/zk
         *
         * @return
         */
        @GetMapping("/consumer/payment/zk")
        public String paymentInfo() {
            return restTemplate.getForObject(INVOKE_URL + "/payment/zk", String.class);
        }
    }
