软负载--springmvc+dubbox+zookeeper，分享下

第一步：下载
maven：  https://maven.apache.org/download.cgi#   
dubbox：  https://github.com/dangdangdotcom/dubbox，
      介绍：http://www.open-open.com/lib/view/open1417426480618.html 
      dubbox： 是一波大牛在dubbo的基础上的扩展，比如加入的rest，升级了spring版本等等。
下载：zookeeper 我这下载的3.4.6  http://apache.fayea.com/zookeeper/zookeeper-3.4.6/
eclipse：要装下maven插件。

第二部：安装
maven： 安装使用自己百度吧，其实就是配置下环境变量，修改下jar包的存放位置
dubbox：用CMD命令到解压出来的dubbox目录执行mvn install -Dmaven.test.skip=true来尝试编译一下dubbo（并将dubbo的jar安装到本地maven库），这样导入eclipse里面就可测试自带的demo了
zookeeper：解压之后到conf目录新建个zoo.cfg,其实就是zoo_sample.cfg上修改的，主要修改两个地方就行
1、# 存储内存中数据库快照的位置，如果不设置参数，更新事务日志将被存储到默认位置。 
dataDir=D:\\apache-zookeeper-3.4.6\\dataDir 
2、# 错误日志的存放位置 
dataLogDir=D:\\apache-zookeeper-3.4.6\\dataLogDir

第三步用eclipse 创建自己的项目，这里我直接把我搭建的项目上传。大家可以自己看下

我消费者  和提供者 都是web项目 直接上传到附近，大家下载下来后倒入eclipse就可以跑了，
消费者是springMVC 解析器配置的jsp和freemarker。
