微服务SpringCloud开弓之Zookeeper服务注册与发现《四》

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

 parent>
    <modelVersion>4.0.0modelVersion>

    <artifactId>cloud-provider-payment8004artifactId>
    <description>Zookeeper服务提供者description>

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

      {
        "value": "port",
        "variable": true
      }
    ]
  }
}

服务节点是临时节点

3、服务消费者

• 新建cloud-consumerzk-order80

• POM

          <dependency>
              <groupId>com.atguigu.springcloudgroupId>
              <artifactId>cloud-api-commonartifactId>

• YML

  server:
    port: 80
  spring:
    application:
      # 服务别名
      name: cloud-consumer-order
    cloud:
      zookeeper:
        # 注册到zookeeper地址
        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);
      }
  }
