先把zookeeper在本地给安装好，

安装方法参考：/article/7578550.html

这里的话讲述了两个工程一个工程是提供服务的，一个工程是调用服务的，因为dubbo是跟spring进行无缝连接的，故功能配置在spring的配置文件中，跟spring进行整合开发

1、工程是以maven进行构建的，使用的jar包如下：



Maven 提供包

发布版和快照版要同时有才能在另的项目中运用。

假如一个项目 为

<modelVersion>4.0.0</modelVersion>

<groupId>cn.com.abel</groupId>

<artifactId>springProject</artifactId>

<packaging>war</packaging>

<version>0.0.1-SNAPSHOT</version>

<name>springProject Maven Webapp</name>

<url>http://maven.apache.org</url>

先mvn intsall后 mvn deploy 上传到服务器

<modelVersion>4.0.0</modelVersion>

<groupId>cn.com.abel</groupId>

<artifactId>springProject</artifactId>

<packaging>war</packaging>

<version>0.0.1</version>

<name>springProject Maven Webapp</name>

<url>http://maven.apache.org</url>

先mvn intsall后 mvn deploy 上传到服务器后在别在项目中用

<dependency>

<groupId>cn.com.abel</groupId>

<artifactId>springProject</artifactId>

<version>0.0.1</version>

</dependency>

<dependency>

<groupId>com.alibaba</groupId>

<artifactId>dubbo</artifactId>

<version>2.3.5</version>

</dependency>

<dependency>

<groupId>org.apache.hadoop</groupId>

<artifactId>zookeeper</artifactId>

<version>3.3.0</version>

</dependency>

<dependency>

<groupId>com.101tec</groupId>

<artifactId>zkclient</artifactId>

<version>0.4</version>

<exclusions>

<exclusion>

<artifactId>org.apache.zookeeper</artifactId>

<groupId>zookeeper</groupId>

</exclusion>

</exclusions>

</dependency>

<dependency>

<groupId>org.jboss.netty</groupId>

<artifactId>netty</artifactId>

<version>3.2.5.Final</version>

</dependency>

<dependency>

<groupId>org.springframework</groupId>

<artifactId>spring-core</artifactId>

<version>${spring.version}</version>

</dependency>

<dependency>

<groupId>org.springframework</groupId>

<artifactId>spring-aop</artifactId>

<version>${spring.version}</version>

</dependency>

<dependency>

<groupId>org.springframework</groupId>

<artifactId>spring-beans</artifactId>

<version>${spring.version}</version>

</dependency>

<dependency>

<groupId>org.springframework</groupId>

<artifactId>spring-asm</artifactId>

<version>${spring.version}</version>

</dependency>

<dependency>

<groupId>org.springframework</groupId>

<artifactId>spring-tx</artifactId>

<version>${spring.version}</version>

</dependency>

<dependency>

<groupId>org.springframework</groupId>

<artifactId>spring-aspects</artifactId>

<version>${spring.version}</version>

</dependency>

<dependency>

<groupId>javassist</groupId>

<artifactId>javassist</artifactId>

<version>3.3</version>

</dependency>

javassist 包要1.5GA以上，不然会报错

<context:component-scan base-package="com.zlh"/>

com.zlh 包下的接口文件要先于xml文件之前

<import resource="classpath:spring-conf.xml"/>

<import resource="classpath:spring-dubbo-client.xml"/>

<import resource="classpath:spring-dubbo.xml"/>

2、服务提供者的工程

a、dubbo-demo-api 定义接口

[java] view
plaincopy

public interface IProcessData {

public String deal(String data);

}

b、dubbo-demo-provider 服务提供者

[java] view
plaincopy

public class ProcessDataImpl implements IProcessData {

/*

* @see com.xxx.bubbo.provider.IProcessData#deal(java.lang.String)

*/

@Override

public String deal(String data) {

try {

Thread.sleep(1000);

} catch (InterruptedException e) {

e.printStackTrace();

}

return "Finished:" + data;

}

}

c、applicationProvider.xml配置

[html] view
plaincopy

<?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"

xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd http://code.alibabatech.com/schema/dubbo http://code.alibabatech.com/schema/dubbo/dubbo.xsd
">

<!-- Application name -->

<dubbo:application name="hello-world-app" />

<!-- registry address, used for service to register itself -->

<dubbo:registry address="zookeeper://127.0.0.1:2181" />

<!-- expose this service through dubbo protocol, through port 20880 -->

<!--

<dubbo:protocol name="dubbo" port="20880" />

<dubbo:protocol name="dubbo" port="9090" server="netty"

client="netty" codec="dubbo" serialization="hessian2" charset="UTF-8"

threadpool="fixed" threads="100" queues="0" iothreads="9" buffer="8192"

accepts="1000" payload="8388608" />

-->

<!-- Service interface Concurrent Control -->

<dubbo:service interface="com.huangjie.dubbo_Service.service.IProcessData"

ref="demoService" executes="10" />

<!-- Default Protocol -->

<!--

<dubbo:protocol server="netty" />

-->

<!-- designate implementation -->

<bean id="demoService" class="com.huangjie.dubbo_Service.service.impl.ProcessDataImpl" />

</beans>

d、启动服务

[java] view
plaincopy

public class DubboProviderMain {

public static void main(String[] args) throws Exception {

ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext(

new String[]{"applicationProvider.xml"});

context.start();

System.out.println("Press any key to exit.");

System.in.read();

}

}

3、服务调用者的工程

a、调用类

[java] view
plaincopy

public class ConsumerThd implements Runnable {

/*

* @see java.lang.Runnable#run()

*/

@Override

public void run() {

ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext(

new String[]{"applicationConsumer.xml"});

context.start();

IProcessData demoService = (IProcessData) context.getBean("demoService"); // get

// service

// invocation

// proxy

String hello = demoService.deal("nihao"); // do invoke!

System.out.println(Thread.currentThread().getName() + " "+hello);

}

public static void main(String[] args) {

new Thread(new ConsumerThd()).start();

/**

* 输出结果：

* Thread-0 Finished:nihao

*/

}

}

b、applicationConsumer.xml配置

[html] view
plaincopy

<?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"

xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd http://code.alibabatech.com/schema/dubbo http://code.alibabatech.com/schema/dubbo/dubbo.xsd
">

<!-- consumer application name -->

<dubbo:application name="consumer-of-helloworld-app" />

<!-- registry address, used for consumer to discover services -->

<dubbo:registry address="zookeeper://127.0.0.1:2181" />

<dubbo:consumer timeout="5000"/>

<!-- which service to consume? -->

<dubbo:reference id="demoService" interface="com.huangjie.dubbo_Service.service.IProcessData" />

</beans>

4、最后需要把zookeeper的服务给启动，在zookeeper安装文件夹下面的bin目录里面的zkServer.cmd给点击运行。不要关闭窗口，保持服务运行



这样整个调用就完成了，这样的好处是只要远程提供ip地址及端口号，以及对外调用的类，客户端就可以调用，客户端不必知道服务端的地址之类的

而且服务端可以开多个zookeeper服务，这样如果其中一个zookeeper 服务死掉了，其他服务还能正常运行

dubbo管理控制台开源部分主要包含：路由规则，动态配置，服务降级，访问控制，权重调整，负载均衡，等管理功能。

1、下载dubbo

地址：

http://code.alibabatech.com/mvn/releases/com/alibaba/dubbo-admin/2.4.1/dubbo-admin-2.4.1.war

本人将tomcat安装在/opt/目录下，先删除tomcat/webapps下自带的ROOT文件夹，将下载的war包解压到webapps/ROOT，命令如下：

[plain] view
plaincopy

unzip dubbo-admin-2.4.1.war -d /opt/apache-tomcat-6.0.37/webapps/ROOT

配置:

(或将dubbo.properties放在当前用户目录下)

[plain] view
plaincopy

vim webapps/ROOT/WEB-INF/dubbo.properties

启动

说明：这边启动tomcat之前必须先启动zookeeper的。

[plain] view
plaincopy

./bin/catalina.sh run

Ctrl + C 停止tomcat

出现以下界面说明安装配置成功，登录密码为root/root
