Maven搭建Zookeeper环境
1、创建一个Maven项目:
更改路径:
设置 groupId 和 artifactId
Maven会加载这个项目:
创建好的目录:
官网Maven的zookeeper配置文件内容:
地址:
http://www.mvnrepository.com/search?q=zookeeper
点击zookeeper:
点击3.4.6:
可以看到配置文件代码了:
具体如下:
<dependency>
<groupId>org.apache.zookeeper</groupId>
<artifactId>zookeeper</artifactId>
<version>3.4.6</version>
</dependency>
修改pom.xml文件:
具体如下:
<dependencies>
<dependency>
<groupId>org.apache.zookeeper</groupId>
<artifactId>zookeeper</artifactId>
<version>3.4.6</version>
</dependency>
</dependencies>
新建一个类:
测试代码如下:
具体代码:
package zk1;
import org.apache.zookeeper.WatchedEvent;
import org.apache.zookeeper.Watcher;
import org.apache.zookeeper.ZooKeeper;
public class ZK1 {
private static String connectString="192.168.1.100:2181";
private static int sessionTimeout=999999;
public static void main(String[] args) throws Exception{
Watcher watcher=new Watcher(){
public void process(WatchedEvent event) {
System.out.println("监听到的事件:"+event);
}
};
final ZooKeeper zookeeper=new ZooKeeper(connectString,sessionTimeout,watcher);
System.out.println("获得连接:"+zookeeper);
final byte[] data=zookeeper.getData("/zk1", watcher, null);
System.out.println("读取的值:"+new String(data));
zookeeper.close();
}
}
Console运行之后的结果:
具体如下:
log4j:WARN No appenders could be found for logger (org.apache.zookeeper.ZooKeeper).
log4j:WARN Please initialize the log4j system properly.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.
获得连接:State:CONNECTING sessionid:0x0 local:null remoteserver:null lastZxid:0 xid:1 sent:0 recv:0 queuedpkts:0 pendingresp:0 queuedevents:0
监听到的事件:WatchedEvent state:SyncConnected type:None path:null
读取的值:mycomputer
