dubbo zookeeper spring 阿里巴巴分布式

windows zookeeper 下载地址 http://mirrors.tuna.tsinghua.edu.cn/apache/zookeeper/zookeeper-3.4.6/
修改zookeeper配置文件zoo-example.cfg改为zoo.cfg，zookeeper默认寻找zoo.cfg配置文件


# 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=/tmp/zookeeper
dataDir=F:\\log\\zookeeper\\data  
dataLogDir=F:\\log\\zookeeper\\log
# the port at which the clients will connect
clientPort=2181
# the maximum number of client connections.
# increase this if you need to handle more clients
#maxClientCnxns=60
#
# 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

启动zookeeper
Window下命令：进入bin目录 ->zkServer.cmd

配置 <dubbo:registry id="zk1" address="quickstart.cloudera:2181" protocol="zookeeper" />

测试成功

,provider 发布后，linux 下 zookeeper path 会增加。 zookeeper 起到注册中心，服务发现的作用

consumer 测试结果：

provider 发布，（这是一种发布方式）
