dubbo是一个分布式服务框架，致力于提供高性能和透明化的RPC远程服务调用方案，是阿里巴巴SOA服务化治理方案的核心框架，每天为2,000+个服务提供3,000,000,000+次访问量支持，并被广泛应用于阿里巴巴集团的各成员站点（其他的详细介绍可以查看dubbo的官网地址http://dubbo.io/，写的很详细！）。
该demo是基于maven搭建的，项目架构基于SpringMVC，这里忽略spring的基本配置，着重介绍下dubbo部分的配置，以及dubbo后台管理系统
一、软件环境
1、zookeeper
下载地址：https://zookeeper.apache.org/releases.html 下载最新版的zookeeper，我这里使用的版本是 zookeeper-3.4.5.tar.gz
2、springMVC （maven方式引入）
3、dubbo （maven方式引入）
二、项目搭建
这里我搭建了三个项目，分别为dubbo-api，dubbo-consumer，dubbo-provider
dubbo-api：主要是接口定义，供dubbo-consumer调用，以及dubbo-provider的service层去实现该接口，分离这一层的好处就是前端项目调用接口时候，直接调用dubbo-api的接口即可，不需要关注后端如何实现；而service层来具体实现该接口，进行业务逻辑处理，不需要关注dubbo-consumer 的controller层如何调用。
dubbo-consumer：主要controller层控制跳转等。
dubbo-provider：主要是service实现，结合数据层实现后端业务逻辑处理。
项目搭建完成之后，的结构图如下：
三、项目配置
1、dubbo-api
Maven配置：
| <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.dubbo</groupId> <artifactId>dubbo-api</artifactId> <packaging>jar</packaging> <version>1.0-SNAPSHOT</version> <name>dubbo-api</name> <url>http://maven.apache.org</url> <build> <plugins> <plugin> <artifactId>maven-compiler-plugin</artifactId> <version>2.0.2</version> <configuration> <source>1.5</source> <target>1.5</target> <fork>true</fork> <meminitial>128m</meminitial> <maxmem>512m</maxmem> <encoding>UTF-8</encoding> </configuration> </plugin> <plugin> <artifactId>maven-eclipse-plugin</artifactId> <version>2.5.1</version> <configuration> <additionalProjectnatures> <projectnature> org.springframework.ide.eclipse.core.springnature </projectnature> </additionalProjectnatures> <additionalBuildcommands> <buildcommand> org.springframework.ide.eclipse.core.springbuilder </buildcommand> </additionalBuildcommands> <downloadSources>false</downloadSources> <downloadJavadocs>false</downloadJavadocs> <wtpversion>1.5</wtpversion> </configuration> </plugin> <!-- 要加上下面的一句，否则执行：mvn package -Dmaven.test.skip=true的时候会报错 --> <plugin> <artifactId>maven-war-plugin</artifactId> <version>2.1.1</version> </plugin> </plugins> </build> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <spring.version>4.0.3.RELEASE</spring.version> <org.codehaus.jackson>1.9.13</org.codehaus.jackson> </properties> <dependencies> <!-- Test --> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.7</version> <scope>test</scope> </dependency>
</dependencies> </project> |
新建TestService接口类
| package com.dubbo.service;
/** * dubbo学习地址：http://blog.csdn.net/aixiaoyang168/article/details/51362675 */ public interface TestService {
/** * 测试发消息 * @param name * @return */ public String sayHello(String name); }
|
注意：这个项目最终打包成jar文件，直接maven引入到另外两个项目中
2、dubbo-consumer

新建TestServiceImpl类
| package com.dubbo.service.impl;
import com.dubbo.service.TestService;
public class TestServiceImpl implements TestService {
public String sayHello(String name) { return name + " service2 say hello word service2!"; }
} |
注意：这里作为服务提供者名称为test_provider，注释很详细，就不一一介绍了，这个项目最终打包成dubbo-service.war放在tomcat或其他容器中运行
好了，经过这么配置之后，我们的项目编码配置部分就大功告成了!
maven编译下三个项目，将dubbo-provider和dubbo-consumer放到tomcat容器中，启动tomcat容器！ 出错啦！ 为啥容器不起来！那是因为我们还少了主要的一步，那就是配置启动zookeeper，不然dubbo去zookeeper注册中心暴露服务地址不成功啦！
四、配置启动zookeeper
最后要启动zookeeper，关于zookeeper的安装配置，可以参考：http://blog.csdn.net/tototuzuoquan/article/details/54003140
启动zookeeper !
再次启动tomcat容器，是不是就成功啦！我们来访问下http://192.168.106.80:8080//dubbo-consumer/test.action?name=toto，看下返回结果是不是正确啦！
