dubbo是一个分布式的服务架构，可直接用于生产环境作为SOA服务框架。

官网首页：http://dubbo.io/ ，官方用户指南 http://dubbo.io/User+Guide-zh.htm上面的几张图画得不错，完全可以当做SOA架构的学习资料

淘宝将这个项目开源出来以后，得到了不少同行的支持，包括：

当当网的扩展版本dubbox ：https://github.com/dangdangdotcom/dubbox

京东的扩展版本jd-hydra: http://www.oschina.net/p/jd-hydra

不过，略有遗憾的是，据说在淘宝内部，dubbo由于跟淘宝另一个类似的框架HSF（非开源）有竞争关系，导致dubbo团队已经解散（参见http://www.oschina.net/news/55059/druid-1-0-9 中的评论），反到是当当网的扩展版本仍在持续发展，墙内开花墙外香。

不管如何，能在阿里、当当、京东这些大型网站正式使用的框架，总不至于差到哪里去。

本文下面的示例均基于当当的dubbox版本，由于dubbox并没向maven提交编译后的jar包，所以只能从github clone代码到本地编译得到jar包。

编译及测试步骤：(以下步骤全在windows环境中完成)

本机先安装github on Windows的客户端，将在path路径中，把git.exe加进去
命令行下 git clone https://github.com/dangdangdotcom/dubbox 把代码拉到本地
mvn install -Dmaven.test.skip=true 跳过测试编译
在本机安装一个zookeeper，参考zoo.cfg如下：

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

intellij Idea中导入源码
运行 \dubbox\dubbo-demo\dubbo-demo-provider\src\test\java\com\alibaba\dubbo\demo\provider\DemoProvider.java

把服务提供方跑起来，成功后，可以在ZK里，用 ls / 看下，会发现zk里多出了一个dubbo的节点，所有服务全注册在这里了

运行\dubbox\dubbo-demo\dubbo-demo-consumer\src\test\java\com\alibaba\dubbo\demo\consumer\DemoConsumer.java

服务消费方调用测试，可以看console里的输出

运行\dubbox\dubbo-demo\dubbo-demo-consumer\src\test\java\com\alibaba\dubbo\demo\consumer\RestClient.java

跑一下rest调用

浏览器访问 http://localhost:8888/services/users/100.xml 或 http://localhost:8888/services/users/100.json

dubbox官方的示例，虽然已经很简单了，但是对于初次接触的人来讲，仍然略显复杂，下面的代码在其基础上简化了一下：

一、先定义服务接口及传输对象DTO

项目结构如下

代码：

User.java

package yjmyzz.dubbo.demo.api;

import org.codehaus.jackson.annotate.JsonProperty;

import javax.validation.constraints.Min;

import javax.validation.constraints.NotNull;

import javax.validation.constraints.Size;

import javax.xml.bind.annotation.XmlAccessType;

import javax.xml.bind.annotation.XmlAccessorType;

import javax.xml.bind.annotation.XmlElement;

import javax.xml.bind.annotation.XmlRootElement;

import java.io.Serializable;

@XmlRootElement

@XmlAccessorType``(XmlAccessType.FIELD)

public class User implements Serializable {

@NotNull

@Min``(1L)

private Long id;

@JsonProperty``(``"username"``)

@XmlElement``(name = "username"``)

@NotNull

@Size``(min = 6``, max = 50``)

private String name;

public User() {

}

public User(Long id, String name) {

this``.id = id;

this``.name = name;

}

public Long getId() {

return id;

}

public void setId(Long id) {

this``.id = id;

}

public String getName() {

return name;

}

public void setName(String name) {

this``.name = name;

}

@Override

public String toString() {

return "User (" +

"id=" + id +

", name='" + name + '\``'' +

')'``;

}

UserService.java

package yjmyzz.dubbo.demo.api;

public interface UserService {

User getUser(Long id);

}

UserRestService.java

package yjmyzz.dubbo.demo.api;

import javax.validation.constraints.Min;

public interface UserRestService {

User getUser(``@Min``(value = 1L, message = "User ID must be greater than 1"``) Long id);

}

pom.xml

View Code

二、定义服务生产者（即：服务接口的实现方）

UserServiceImpl.java

package yjmyzz.dubbo.demo.provider;

import yjmyzz.dubbo.demo.api.User;

import yjmyzz.dubbo.demo.api.UserService;

public class UserServiceImpl implements UserService {

public User getUser(Long id) {

return new User(id, "username" + id);

}

UserRestServiceImpl.java

package yjmyzz.dubbo.demo.provider;

import com.alibaba.dubbo.rpc.RpcContext;

import com.alibaba.dubbo.rpc.protocol.rest.support.ContentType;

import yjmyzz.dubbo.demo.api.User;

import yjmyzz.dubbo.demo.api.UserRestService;

import yjmyzz.dubbo.demo.api.UserService;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

import javax.ws.rs.*;

import javax.ws.rs.core.MediaType;

@Path``(``"users"``)

@Consumes``({MediaType.APPLICATION_JSON, MediaType.TEXT_XML})

@Produces``({ContentType.APPLICATION_JSON_UTF_8, ContentType.TEXT_XML_UTF_8})

public class UserRestServiceImpl implements UserRestService {

private UserService userService;

public void setUserService(UserService userService) {

this``.userService = userService;

}

@GET

@Path``(``"{id : \\d+}"``)

public User getUser(``@PathParam``(``"id"``) Long id) {

if (RpcContext.getContext().getRequest(HttpServletRequest.``class``) != null``) {

System.out.println(``"Client IP address from RpcContext: " + RpcContext.getContext().getRequest(HttpServletRequest.``class``).getRemoteAddr());

}

if (RpcContext.getContext().getResponse(HttpServletResponse.``class``) != null``) {

System.out.println(``"Response object from RpcContext: " + RpcContext.getContext().getResponse(HttpServletResponse.``class``));

}

return userService.getUser(id);

}

DemoProvider.java

package yjmyzz.dubbo.demo.provider;

import org.springframework.context.support.ClassPathXmlApplicationContext;

import java.io.IOException;

public class DemoProvider {

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

ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext(``"classpath*:META-INF/spring/*.xml"``);

context.start();

System.out.println(``"服务已经启动..."``);

System.in.read();

}

测试时，运行DemoProvider中的main方法即可启动服务，所有服务注册在ZooKeeper，层次结构类似下面这样：

/dubbo
/dubbo/yjmyzz.dubbo.demo.api.UserRestService
/dubbo/yjmyzz.dubbo.demo.api.UserRestService/providers
/dubbo/yjmyzz.dubbo.demo.api.UserRestService/configurators
/dubbo/yjmyzz.dubbo.demo.api.UserService
/dubbo/yjmyzz.dubbo.demo.api.UserService/providers
/dubbo/yjmyzz.dubbo.demo.api.UserService/configurators

三、服务消费方

DemoConsumer.java

package yjmyzz.dubbo.demo.consumer;

import org.springframework.context.support.ClassPathXmlApplicationContext;

import yjmyzz.dubbo.demo.api.UserService;

import javax.ws.rs.client.Client;

import javax.ws.rs.client.ClientBuilder;

import javax.ws.rs.client.WebTarget;

import javax.ws.rs.core.Response;

public class DemoConsumer {

public static void main(String[] args) {

final String port = "8888"``;

getUser(``"http://localhost:" + port + "/services/users/1.json"``);

getUser(``"http://localhost:" + port + "/services/users/1.xml"``);

ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext(``"classpath*:META-INF/spring/*.xml"``);

context.start();

UserService userService = context.getBean(UserService.``class``);

System.out.println(userService.getUser(1L));

}

private static void getUser(String url) {

System.out.println(``"Getting user via " + url);

Client client = ClientBuilder.newClient();

WebTarget target = client.target(url);

Response response = target.request().get();

try {

if (response.getStatus() != 200``) {

throw new RuntimeException(``"Failed with HTTP error code : " + response.getStatus());

}

System.out.println(``"Successfully got result: " + response.readEntity(String.``class``));

} finally {

response.close();

client.close();

}

其它注意事项：

dubbo构架中，zk充着“服务注册中心”的角色，所以生产者与消费者的xml配置文件中，都要配置zk地址，如果zk采用集群部署时，配置写法参考下面这样：

<dubbo:registry address=“zookeeper://172.28.*.102:2181?backup=172.28.*.102:2182,172.28.*.102:2183”/>

dubbo还有一个管理界面，用于服务治理，包括启用/禁用服务，设置服务的路由规则（即：A地址的Consumer直接调用B机器的Provider，而不是由负载均衡算法分配）等等。

使用方法：将dubbo-admin这个项目编译成war包后，部署到jetty或其它兼容web server即可（当然要修改\WEB-INF\dubbo.properties里zk的地址）

部署完成后，访问管理界面时，默认用户名，密码均是root。

另外dubbo-monitor项目用于性能监控，结合监控产生的数据，再套上一些图表展示的框架，可以用图表方式直观展示各种指标。

注：官网给出的dubbo-admin采用的webx架构有点老，而且除了淘宝之外，几乎没人在用，dubbo-monitor-simple界面也比较古朴，所以社区也人对其做了扩展，详情参考另一篇博客dubbox 的各种管理和监管

2016-02-25：dubbox依赖的spring虽然升级成3.x了，但版本还是有点低，spring都已经4.x了，为了方便我fork了一份，升级成spring 4.x 同时增加了log4j2的日志组件支持，详情见：dubbox升级spring到4.x及添加log4j2支持
