Curator实现zookeeper分布式锁

Curator实现zookeeper分布式锁简单案例
解决了传统分布式锁开发的繁琐，以及不能并发的问题
Curator官网：

需要导入依赖：

<!-- https://mvnrepository.com/artifact/org.apache.curator/curator-recipes -->
<dependency>
 **加粗样式**   <groupId>org.apache.curator</groupId>

流程连接客户端，创建锁

package com.example.zjh.zookeeper.CuratorFrame;

import lombok.SneakyThrows;
import org.apache.curator.framework.CuratorFramework;
import org.apache.curator.framework.CuratorFrameworkFactory;
import org.apache.curator.framework.recipes.locks.InterProcessMutex;
import org.apache.curator.retry.ExponentialBackoffRetry;

public class CuratorFrame {
    
    

    public static void main(String[] args) {
    
    
        // 分布式锁1
        // 参数：客户端连接，节点名
        InterProcessMutex lock1 = new InterProcessMutex(getLink(), "/locks");
        // 分布式锁2
//        InterProcessMutex lock2 = new InterProcessMutex(getLink(), "/locks");
        // 线程
        new Thread(new Runnable() {
    
    
            @SneakyThrows
            @Override
            public void run() {
    
    
                // lock1拿锁
                lock1.acquire();
                System.out.println("lock1拿到锁");
                // lock1释放锁
                lock1.release();
                System.out.println("lock1解锁锁");
            }
        }).start();
    }
    private static CuratorFramework getLink() {
    
    
        // 失败尝试构建次数(3000ms,3次)
        final ExponentialBackoffRetry exponentialBackoffRetry = new ExponentialBackoffRetry(3000, 3);
        // 构建连接
        // 地址
        final CuratorFramework linkZk = CuratorFrameworkFactory.builder().connectString("zookeeper集群地址")
                // 连接超时时间，单位ms
                .connectionTimeoutMs(20000)
                // 会话超时时间，单位ms
                .sessionTimeoutMs(20000)
                // 重试
                .retryPolicy(exponentialBackoffRetry).build();
        // 启动客户端
        linkZk.start();
        // linkZk也能取到客户端节点以及数据
        System.out.println("zookeeper连接成功");
        return linkZk;
    }
