Windows下dubbo环境搭建及初步使用

一、dubbo简介

　　Dubbo是阿里巴巴公司开源的一个高性能优秀的服务框架，使得应用可通过高性能的 RPC 实现服务的输出和输入功能，可以和Spring框架无缝集成。

二、环境准备

　　本案例使用环境：jdk（1.8）、maven（3.2+）、zookeeper（3.4.10）、eclipse（Oxygen.3a Release (4.7.3a)）、tomcat（tomcat8）

　　a、搭建注册中心（jdk、maven、tomcat、eclipse集成可以自行搜索安装）

　　　　1、本次实例使用zookeeper作为注册中心，下载地址：http://mirrors.hust.edu.cn/apache/zookeeper/zookeeper-3.4.10/zookeeper-3.4.10.tar.gz

　　　　也可以去官网下载想要的版本，官网地址：http://zookeeper.apache.org/releases.html

　　　　2、解压 zookeeper-3.4.10.tar.gz，进入解压后conf目录下，复制zoo_sample.cfg文件，重命名为zoo.cfg即可

　　　　3、进入解压后bin目录，点击zkServer.cmd即可

　　b、搭建dubbo-admin控制台(可选)

　　　　1、下载源码安装，下载地址：https://github.com/apache/incubator-dubbo/tree/dubbo-2.5.8

　　　　也可以选择下载对应的版本。

　　　　2、解压后，打开cmd进入dubbo-admin目录下，如我解压的目录为：D:\Test\dubbo-master\dubbo-admin，在cmd下输入命令：mvn clean install

　　　　3、在target目录下生成dubbo-admin-2.5.8.war，然后将该war包放入tomcat的webapps目录下，启动tomcat，访问localhost:[端口]/dubbo-admin-2.5.8，输入默认的用户名和密码：root/root

　　　　例如我访问的地址为：http://localhost:8088/dubbo-admin-2.5.8/

三、基于步骤二搭建的环境，使用ide开发JavaEE项目

　　a、新建一个maven父项目dubbo-demo-master，和三个maven子模块dubbo-demo-interface、dubbo-demo-service、dubbo-demo-web（不知道如何新建百度搜索:eclipse搭建maven多module项目）

　　　　1、完成后，添加相关项目依赖和插件，最后其dubbo-demo-master的pom.xml内容为（该maven工程packaging属性为pom），删除该工程的src目录（父工程不需要，只管理依赖）：

import org.moy.maven.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;

<html>
<head>
<meta charset="UTF-8">
<title>Insert title here</title>
</head>
<body>
    hello world!
</body>
</html>

四、集成测试

　　　1、确保zookeeper是启动的

　　　2、打开cmd进入dubbo-demo-master的pom.xml同级目录下，运行命令：mvn clean install

　　　3、打开cmd进入dubbo-demo-service的pom.xml同级目录下，运行命令：mvn clean tomcat:run -Dmaven.tomcat.port=8098

　　　4、打开cmd进入dubbo-demo-web的pom.xml同级目录下，运行命令：mvn clean tomcat:run -Dmaven.tomcat.port=8099

　　　5、打开浏览器访问：http://localhost:8099/dubbo-demo-web/users/list.do接口，（接口数据是运行UserMapperTest单元测试来的）

　　　6、dubbo-demo-service工程实现接口，运行时向zookeeper注册接口信息，dubbo-demo-web工程只需要依赖接口，在通过spring原有的方式调用接口，其中dubbo帮我们从zookeeper中查找相应接口信息，通过默认dubbo协议帮我们完成了rpc调用。可以通过控制台http://localhost:8088/dubbo-admin-2.5.8/查看对应服务，对服务进行治理。
