dubbo 试用全过程

1.下载地址

https://github.com/alibaba/dubbo/

2.导入IDE

cd ~/dubbo
mvn eclipse:eclipse（执行了两次mvn下载，第一次执行失败有些jar没下载下来，重新执行成功）

Eclipse -> Menu -> File -> Import -> Exsiting Projects to Workspace -> Browse -> Finish

3. 如果修改dubbo源码则需要重新构建dubbo

cd ~/dubbo
mvn clean install -Dmaven.test.skip
cd dubbo/target

4.Install the zookeeper registry:

cd ~
wget http://www.apache.org/dist//zookeeper/zookeeper-3.3.3/zookeeper-3.3.3.tar.gz
tar zxvf zookeeper-3.3.3.tar.gz
cd zookeeper-3.3.3/conf
cp zoo_sample.cfg zoo.cfg
vi zoo.cfg
- edit: dataDir=/home/xxx/data
cd ../bin
./zkServer.sh start
cd ~/dubbo/dubbo-demo-provider/conf
vi dubbo.properties
- edit: dubbo.registry.adddress=zookeeper://127.0.0.1:2181
cd ../bin
./restart.sh
cd ~/dubbo/dubbo-demo-consumer/conf
vi dubbo.properties
- edit: dubbo.registry.adddress=zookeeper://127.0.0.1:2181
cd ../bin
./restart.sh
cd ~/dubbo/dubbo-simple-monitor/conf
vi dubbo.properties
- edit: dubbo.registry.adddress=zookeeper://127.0.0.1:2181
cd ../bin
./restart.sh

5.启动过程

00zkServer.cmd01start_provider.bat02start_consumer.bat（可选，基本不用）03start_monitor.bat （可选，监控使用，会占用本地8080端口）04start_admin.bat（基本不用，管理控制器部署在tomcat下即可，dubbo-admin-2.5.4-SNAPSHOT.war）

6.服务端开发
通过dubbo自带例子下进行开发，采用maven构建，mvn build

7.客户端开发
通过java工程开发，但是至少需要导入如下jar

8.管理控制台
http://127.0.0.1:8087（8080端口被监控应用占用了，找了好长时间的原因）dubbo-admin-2.5.4-SNAPSHOT.war（该war一定要部署在tomcat/webapp/ROOT下面）root/rooot消费者访问服务必须长连接才能在管理控制台看见消费者，因为是基于zookeeper进行连接的，一但客户端线程结束，则立马会断开zookeeper的连接
9.客户端事例代码

 1 package com.rigid;

 3 import java.io.IOException;
 4
 5 import org.springframework.context.support.FileSystemXmlApplicationContext;
 6
 7 import com.alibaba.dubbo.demo.VendorService;

 9 public class Main3 {
10
11     /**
12      * @param args
13      * @throws IOException
14      */
15     public static void main(String[] args) throws IOException {
16         FileSystemXmlApplicationContext context = new FileSystemXmlApplicationContext(
17                 "/bin/conf/spring.*");
18
19         context.start();
20
21         VendorService vendorService = (VendorService) context.getBean("vendorService");
22
23         vendorService.createVendor("rigid");
24
25         System.in.read();
26
27     }
