Curator有2个实现：
第一个：
package curator.counters;
import org.apache.curator.RetryPolicy;
import org.apache.curator.framework.CuratorFramework;
import org.apache.curator.framework.CuratorFrameworkFactory;
import org.apache.curator.framework.recipes.shared.SharedCount;
import org.apache.curator.framework.recipes.shared.SharedCountListener;
import org.apache.curator.framework.recipes.shared.SharedCountReader;
import org.apache.curator.framework.state.ConnectionState;
import org.apache.curator.retry.ExponentialBackoffRetry;
public class SharedCounterDemo {
public static void main(String[] args) throws Exception {
RetryPolicy retryPolicy = new ExponentialBackoffRetry(1000, 3);
final CuratorFramework client = CuratorFrameworkFactory.builder().connectString("127.0.0.1:2181").sessionTimeoutMs(5000).connectionTimeoutMs(10000).retryPolicy(retryPolicy).namespace("test").build();
client.start();
SharedCount count = new SharedCount(client,"/cut",0);
count.start();
count.addListener(new SharedCountListener(){
@Override
public void stateChanged(CuratorFramework client, ConnectionState newState) {
}
@Override
public void countHasChanged(SharedCountReader sharedCount, int newCount) throws Exception {
System.err.println("sharedCount.getCount : "+sharedCount.getCount());
System.err.println(newCount);
}});
Thread.currentThread().sleep(5000);
count.setCount(5);
System.in.read();
}
}第二个：
package curator.counters;
import org.apache.curator.RetryPolicy;
import org.apache.curator.framework.CuratorFramework;
import org.apache.curator.framework.CuratorFrameworkFactory;
import org.apache.curator.framework.recipes.atomic.AtomicValue;
import org.apache.curator.framework.recipes.atomic.DistributedAtomicInteger;
import org.apache.curator.retry.ExponentialBackoffRetry;
import org.apache.curator.retry.RetryNTimes;
public class DistributedAtomicIntegerDemo {
public static void main(String[] args) throws Exception {
RetryPolicy retryPolicy = new ExponentialBackoffRetry(1000, 3);
final CuratorFramework client = CuratorFrameworkFactory.builder().connectString("127.0.0.1:2181").sessionTimeoutMs(5000).connectionTimeoutMs(10000).retryPolicy(retryPolicy).namespace("test").build();
client.start();
DistributedAtomicInteger atomicInteger = new DistributedAtomicInteger(client,"/autlog",new RetryNTimes(32,1000));
AtomicValue rc = atomicInteger.add(8);
System.out.println("success:" + rc.succeeded() + ";before:" + rc.preValue() + ";after:" + rc.postValue());
System.in.read();
}
