1.zookeeper

http://zookeeper.apache.org/ 官网下载，然后安装

启动时，需要将 zoo_sample.cfg 改成 zoo.cfg

# The number of milliseconds of each tick
tickTime=2000
# The number of ticks that the initial 
# synchronization phase can take
initLimit=10
# The number of ticks that can pass between 
# sending a request and getting an acknowledgement
syncLimit=5
# the directory where the snapshot is stored.
# do not use /tmp for storage, /tmp here is just 
# example sakes.
dataDir=D:\\Zookeeper-3.4.5\\data
# the port at which the clients will connect
clientPort=2181
#
# Be sure to read the maintenance section of the 
# administrator guide before turning on autopurge.
#
# http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance
#
# The number of snapshots to retain in dataDir
#autopurge.snapRetainCount=3
# Purge task interval in hours
# Set to "0" to disable auto purge feature
#autopurge.purgeInterval=1

2. dubbo-demo-api  定义接口

public interface IProcessData {
	public String deal(String data);
}

3.dubbo-demo-provider 服务提供者

public class ProcessDataImpl implements IProcessData {

	/* 
	 * @see com.xxx.bubbo.provider.IProcessData#deal(java.lang.String)
	 */
	@Override
	public String deal(String data) {
		try {
			Thread.sleep(1000);
		} catch (InterruptedException e) {
			e.printStackTrace();
		}
		return "Finished:" + data;
	}
}
