Case
The registration center can be implemented using Eureka. This is relatively simple. You can see the previous example spring-cloud.
So how to use zookeeper to realize the registration center?
Based on spring cloud, we can also implement it very simply.
1. Use the previously built zookeeper cluster, zookeeper cluster
2, create a new maven project
1, the POM file is as follows:
xmlns:xsi= "http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org /xsd/maven-4.0.0.xsd">
org.springframework.boot
spring-boot-starter-parent< /artifactId>
2.1.4.RELEASE
4.0.0
com.jane
zookeeper-register-server
1.0-SNAPSHOT
1.8
Greenwich.SR1< /spring-cloud.version>
org.springframework.boot
spring-boot-starter-web
org.springframework.boot
spring-boot-starter-actuator < br />
org.springframework.cloud
spring-cloud-starter-zookeeper-discovery
org.projectlombok
lombok < br />true
org.springframework.boot
spring -boot-starter-test
test
org.springframework.cloud< /groupId>
spring-cloud-dependencies
${spring-cloud.version}
pom
import
org.springframework.boot
spring-boot-maven-plugin
< /plugin>
2, the startup files are as follows:
package com.jane.zk;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cache.annotation.EnableCaching;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;
@SpringBootApplication
@EnableCaching
@EnableDiscoveryClient
public class OrderServiceApplication {
public static void main(String[] args) {
SpringApplication.run(OrderServiceApplication.class, args);
}
}
3. The configuration file is as follows:
spring.application.name=order-service
management.endpoints.web.exposure .include=*
management.endpoint.health.show-details=always
server.port=0
spring.cloud.zookeeper.connect-string= www.****.com:2181,www.*****.club:2181,www.*****.club:2181
After starting, check the zookeeper node h4>
1. The service nodes are located under the directory services: 
2. There is a corresponding service node in the services directory
3. View the node information corresponding to the service node
So far, a service is successfully registered to zookeeper.
