windows下运行项目：

1.启动zookeeper：找到zookeeper的bin目录，双击zkServer.cmd。执行完效果如下：

（注：我的第二步，启动dubbo服务，用执行jar的方式启动，比较繁琐。并不适用，最好是改变pom文件，打包编译的配置，用到assembly，install之后，把.tar.gz包上传到服务器，解压，里面就包含了lib目录，直接运行类似于./start.sh start命令就好了，不用像我这样启动dubbo服务，可我一直没搞出来，知道的请告诉我，再此先谢谢大神）

2.启动dubbo服务：选中banksteel-yesen(服务提供方)右键--->Run As---> Maven clean--->Maven install一下。

没有报错的话，在target目录下找到banksteel-yesen-provider-0.0.1-SNAPSHOT.jar 和 lib，然后一起copy出来,比如放d盘下，执行jar。

命令： java -jar banksteel-yesen-provider-0.0.1-SNAPSHOT.jar

我们看到dubbo服务已经启动了。

3.连接zookeeper客户端，我们可以看到会多出一个/dubbo节点。

双击zkCli.cmd，然后输入 h ,按enter键，然后查看zookeeper的一些命令。

4.启动服务消费者web工程。

tomcat启动，我就不说了，运行的效果如下：

5.dubbo监控中心的使用：

dubbo-monitor-simple-2.5.4-SNAPSHOT-assembly.tar.gz 解压后。进入conf目录，找到dubbo.properties,编辑,保存。

进入bin目录，双击start.bat。

然后打开浏览器，输入： http:locahost:8080/services.html。（localhost其实是zookeeper服务器的地址），效果如下：

由上图可了解有哪些dubbo服务，以及服务的消费情况。
