Springboot-dubbo-zookeeper 项目搭建

一、dubbo开发者文档：http://dubbo.apache.org/zh-cn/docs/user/preface/background.html

二、zookeeper安装：

1. 去Apache Zookeeper官网 https://www.apache.org/dyn/closer.cgi/zookeeper/

选择最新版本下载即可

2. 解压下载后的压缩包，打开【解压包名/conf/】，新建文件zoo.cfg，放入以下内容

# The number of milliseconds of each tick  心跳间隔毫秒每次
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.    镜像数据位置
# do not use /tmp for storage, /tmp here is just
# example sakes.
dataDir=E:\\zookeeper-other\\data
#log
dataLogDir=E:\\zookeeper-other\\logs

# 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

3. 进入【解压包名/bin】，点击zkServer.cmd 启动zookeeper，zookeeper配置完成

三、项目搭建

1. 目录

父项目---> ccm-dubbo

通用项目---> dubbo-api

生产者项目---> dubbo-provider

消费者项目---> dubbo-consumer

对应的pom.xml分为列在下面：
