duboo入门

1. 先搭建zookeeper环境

   下载Zookeeper-3.4.6.tar.gz  地址http://www.apache.org/dist/zookeeper/

   然后解压： 然后在对应的zookeeper-3.4.6/conf 下有一个文件zoo_sample.cfg的这个文件里面配置了监听客户端连接的端口等一些信息，Zookeeper 在启动时会找zoo.cfg这个文件作为默认配置文件,所以我们复制一个名称为zoo.cfg的文件

   修改里面配置为：
   # The number of milliseconds of each tick
   tickTime=2000
   # The number of ticks that the initial
   initLimit=10
   # The number of ticks that can pass between
   syncLimit=5
   # the directory where the snapshot is stored.
   dataDir=D://tools//zookeeper//tmp
   dataLogDir=D://tools//zookeeper//logs
   # the port at which the clients will connect
   clientPort=2181
   #autopurge.snapRetainCount=3
   # Set to "0" to disable auto purge feature
   #autopurge.purgeInterval=1
   然后启动zookeeper  在安装目录的bin目录下 zkServer.cmd
   

2. 编写duboo简单demo

   代码目录如下：

   
   

   ｃｌｉｅｎｔ
   

   package duboo.client;
   
   import org.springframework.context.support.ClassPathXmlApplicationContext;
   
   import cn.HelloWorld;
   
   public class ConsumerThd implements Runnable {
       public void run() {
           ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext(
                   new String[] { "applicationConsumer.xml" });
           context.start();
           HelloWorld helloWorld = (HelloWorld) context.getBean("demoService");
           String hello = helloWorld.hello("duboo");
           System.out.println(hello);
       }
   
       public static void main(String[] args) {
           new Thread(new ConsumerThd()).start();
       }
   }

3. package cn;
   
   /**
    * Created by zhouq on 2016/3/21.
    */
   public interface HelloWorld {
   
       public String hello(String name);
   }

4. package cn.impl;
   
   import cn.HelloWorld;
   
   public class HelloWorldImpl implements HelloWorld {
       public String hello(String name) {
   
           return "hello" + name;
       }
   }

5. package cn;
   
   import java.io.IOException;
   import org.springframework.context.support.ClassPathXmlApplicationContext;
   
   
   public class DubboProviderMain {
       public static void main(String[] args) throws IOException {
   
           ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext(
                   new String[] { "applicationProvider.xml" });
           context.start();
           System.out.println("Press any key to exit.");
           System.in.read();
       }
   }

6. 配置文件：

7. applicationConsumer.xml

8. <?xml version="1.0" encoding="UTF-8"?>
   <beans xmlns="http://www.springframework.org/schema/beans"
          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:dubbo="http://code.alibabatech.com/schema/dubbo"

   </beans>

9. applicationProvider.xml

10. <?xml version="1.0" encoding="UTF-8"?>
