使用curator需要引入zookeeper jar包吗

Curator是Netflix开源的一套ZooKeeper客户端框架，用它来操作zookeeper更加简单方便，按Curator官方所比喻的，guava to JAVA， Curator to Zookeeper，Curator采用了fluent风格的代码，非常简洁。
主要看下，使用curator操作zookeeper的一些基础例子：
主要的功能：
1，在zk上添加，或更新数据
2，删除zk节点上数据
3，读取某个节点上的数据
4，上传一些本地文件到zk节点上
5，检查zookeeper上是否存在某个节点路径
核心代码如下：
package com.qin.curator.zk;
import java.io.File;
import java.util.List;
import org.apache.commons.io.FileUtils;
import org.apache.curator.CuratorZookeeperClient;
import org.apache.curator.RetryPolicy;
import org.apache.curator.framework.CuratorFramework;
import org.apache.curator.framework.CuratorFrameworkFactory;
import org.apache.curator.framework.CuratorFrameworkFactory.Builder;
import org.apache.curator.framework.api.CreateBuilder;
import org.apache.curator.retry.ExponentialBackoffRetry;
import org.apache.zookeeper.WatchedEvent;
import org.apache.zookeeper.Watcher;
import org.apache.zookeeper.ZKUtil;
import framework.CrudExamples;

public class CuratorTools {
static CuratorFramework zkclient=null;
static String nameSpace="php";
static {
String zkhost="192.168.46.22:2181";//zk的host
RetryPolicy rp=new ExponentialBackoffRetry(1000, 3);//重试机制
Builder builder = CuratorFrameworkFactory.builder().connectString(zkhost)
.connectionTimeoutMs(5000)
.sessionTimeoutMs(5000)
.retryPolicy(rp);
builder.namespace(nameSpace);
CuratorFramework zclient = builder.build();
zkclient=zclient;
zkclient.start();// 放在这前面执行
zkclient.newNamespaceAwareEnsurePath(nameSpace);
}
public static void main(String[] args)throws Exception {
CuratorTools ct=new CuratorTools();
//ct.getListChildren("/zk/bb");
//ct.upload("/jianli/123.txt", "D:\\123.txt");
//ct.createrOrUpdate("/zk/cc334/zzz","c");
//ct.delete("/qinb/bb");
//ct.checkExist("/zk");
ct.read("/jianli/123.txt");
zkclient.close();
}

public void createrOrUpdate(String path,String content)throws Exception{
zkclient.newNamespaceAwareEnsurePath(path).ensure(zkclient.getZookeeperClient());
zkclient.setData().forPath(path,content.getBytes());
System.out.println("添加成功！！！");
}

public void delete(String path)throws Exception{
zkclient.delete().guaranteed().deletingChildrenIfNeeded().forPath(path);
System.out.println("删除成功!");
}

public void checkExist(String path)throws Exception{
if(zkclient.checkExists().forPath(path)==null){
System.out.println("路径不存在!");
}else{
System.out.println("路径已经存在!");
}
}

public void read(String path)throws Exception{
String data=new String(zkclient.getData().forPath(path),"gbk");
System.out.println("读取的数据:" data);
}

public void getListChildren(String path)throws Exception{
List paths=zkclient.getChildren().forPath(path);
for(String p:paths){
System.out.println(p);
}
}

public void upload(String zkPath,String localpath)throws Exception{
createrOrUpdate(zkPath, "");//创建路径
byte[] bs=FileUtils.readFileToByteArray(new File(localpath));
zkclient.setData().forPath(zkPath, bs);
System.out.println("上传文件成功！");
}
}
