　代码：　

package com.toov5.controller;

import org.I0Itec.zkclient.ZkClient;

public class zkTest {

      public static void main(String[] args) {
        String connection = "192.168.91.1:2181,192.168.91.3:2181,192.168.91.4:2181";
        ZkClient zkClient = new ZkClient(connection);
        zkClient.createPersistent("/toov5_01");
        zkClient.close();
    }
    
    
}

 

运行查看结果：

 

SpringBoot整合：

配置文件抽取到 yml中

connection:192.168.91.1:2181,192.168.91.3:2181,192.168.91.4:2181
 　　

 整合：

package com.toov5.service;

import org.I0Itec.zkclient.ZkClient;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Service;

@Service
public class zkService {
   @Value("{connection}")
   private String connection;
    private ZkClient zkClient = new ZkClient(connection);
   
   public String creteNode(String path){   
       try {
           zkClient.createPersistent(path); //没返回结果 所以用try catch 方式解决哦
           return "ok";
    } catch (Exception e) {
           return "fail";
    }  
   }
     
    
}
