SpringCloud注册进Zookeeper

1. 首先启动zk集群
   zk搭建可查看以前博客

2. 客户端程序
   pom.xml

   	<!-- SpringBoot 整合Zookeeper客户端 -->
       <dependency>
           <groupId>org.springframework.cloud</groupId>
           <artifactId>spring-cloud-starter-zookeeper-discovery</artifactId>
       </dependency>
   
       <dependency>
           <groupId>org.springframework.boot</groupId>
           <artifactId>spring-boot-starter-web</artifactId>
       </dependency>
   
       <dependency>
           <groupId>org.springframework.boot</groupId>
           <artifactId>spring-boot-starter-actuator</artifactId>
       </dependency>
   

   application.yml

   # 8004 表示注册到zookeeper服务器的支付服务提供者端口号
   server:
     port: 8004
   
   spring:
     application:
       # 服务别名
       name: cloud-provider-payment
     cloud:
       zookeeper:
         connect-string: centos3:2181,centos4:2181,centos5:2181
   

   启动类

   @SpringBootApplication
   //该注解用于向使用consul或者zookeeper作为注册中心时注册服务
   @EnableDiscoveryClient
   public class PaymentApplication8004 {
         
         
       public static void main(String[] args) {
         
         
           SpringApplication.run(PaymentApplication8004.class,args);
       }
   }
   

   测试类

   @RestController
   @Slf4j
   public class PaymentController {
         
         
   
       @Value("${server.port}")
       private String serverPort;
   
       @GetMapping("/payment/zk")
       public String paymentTestZk(){
         
         
           return "springcloud with zookeeper: "+serverPort+"\t"+ UUID.randomUUID().toString();
       }
   
   }
   

   启动服务

3. 测试
   

4. 查看zk注册信息
   可以看到多了services节点
   可以看到注册的cloud-provider-pyment服务。
   该节点保存了微服务的基本信息
   格式化一下json串
