---》下载dubbox
* dubbox扩展了dubbo，采用dubbox进行测试
* 地址：https://github.com/dangdangdotcom/dubbox
* 文档参考dubbo的文档，写的很详细。http://dubbo.io/User+Guide-zh.htm
---》编译dubbox
* mvn clean install -Dmaven.test.skip
* dubbox编译没啥问题，碰到问题可以再尝试编译一次，dubbo会遇到一些确库的问题，但网上都有解决方案；
---》安装zookeeper
* 大数据里必用的一个东东，也用到了这里，too strong！
* 下载：http://mirrors.tuna.tsinghua.edu.cn/apache/zookeeper/zookeeper-3.4.8/
* 解压
* 配置，
创建文件zoo.cfg，添加如下内容，dataDir和：dataLogDir改为自己的路径
tickTime=2000
initLimit=10
syncLimit=5
dataDir=D:/java/zookeeper-3.4.6/data
dataLogDir=D:/java/zookeeper-3.4.6/log
clientPort=2181
server.1=localhost:2287:3387
然后输入 bin/zkServer.cmd 启用zookeeper
---》撰写demo
* dubbox自带了demo，可以查看，比较复杂点，dubbo的比较简单，也有说明文档。
* 创建三个工程 myDubbox-api（开放的api）、myDubbox-provider（服务提供端）、myDubbox-consumer（服务调用端）
************ myDubbox-api 中代码************
》HelloService接口
public interface HelloService {
String hello(String name);
}
************ myDubbox-provider 中的主要代码 ************
》HelloServiceImpl实现类
public class HelloServiceImpl implements HelloService {
public String hello(String name) {
return "hello " + name;
}
}
》 DemoProvider （负责启动服务）
public class DemoProvider {
public static void main(String[] args) throws IOException {
ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("classpath*:/*.xml");
context.start();
System.out.println("服务已经启动...");
System.in.read();
}
}
》pom.xml 文件（myDubbox-api为依赖的api jar包）
》duboox、spring相关配置文件（dubbo:registry为zookeeper的地址）
xmlns:dubbo="http://code.alibabatech.com/schema/dubbo"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
http://code.alibabatech.com/schema/dubbo http://code.alibabatech.com/schema/dubbo/dubbo.xsd">
》log4j文件
略
************ myDubbox-consumer工程主要代码 ************
》Consumer（负责调用服务）
public class Consumer {
public static void main(String[] args) throws Exception {
ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext(new String[] {"dubbo-demo-consumer.xml"});
context.start();
HelloService demoService = (HelloService)context.getBean("helloService"); // 获取远程服务代理
String hello = demoService.hello("world"); // 执行远程方法
System.out.println( hello ); // 显示调用结果
}
}
》duboox、spring相关配置文件（dubbo:registry为zookeeper的地址）
xmlns:dubbo="http://code.alibabatech.com/schema/dubbo"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
http://code.alibabatech.com/schema/dubbo http://code.alibabatech.com/schema/dubbo/dubbo.xsd">
》log4j文件
略
---》测试

---》部署 dubbo-admin，查看服务部署和调用情况
* 把dubbo-admin-2.8.4.war 部署到tomcat
* 修改 \dubbo-admin-2.8.4\WEB-INF\dubbo.properties 下的dubbo.registry.address
* 此文件还可以配置登录密码
