dubbo是一個分布式服務架構，緻力于提供高性能和透明化的rpc遠端服務調用方案，是阿裡巴巴soa服務化治理方案的核心架構，每天為2,000+個服務提供3,000,000,000+次通路量支援，并被廣泛應用于阿裡巴巴集團的各成員站點（其他的詳細介紹可以檢視dubbo的官網位址http://dubbo.io/，寫的很詳細！）。
一、軟體環境
1、zookeeper
2、springmvc （maven方式引入）
3、dubbo （maven方式引入）
二、項目搭建
這裡我搭建了三個項目，分别為dubbo-api，dubbo-consumer，dubbo-provider
dubbo-api：主要是接口定義，供dubbo-consumer調用，以及dubbo-provider的service層去實作該接口，分離這一層的好處就是前端項目調用接口時候，直接調用dubbo-api的接口即可，不需要關注後端如何實作；而service層來具體實作該接口，進行業務邏輯處理，不需要關注dubbo-consumer 的controller層如何調用。
dubbo-consumer：主要controller層控制跳轉等。
dubbo-provider：主要是service實作，結合資料層實作後端業務邏輯處理。
項目搭建完成之後，的結構圖如下：
三、項目配置

maven配置：

建立testservice接口類
package com.dubbo.service;
/**
* dubbo學習位址：http://blog.csdn.net/aixiaoyang168/article/details/51362675
*/
public interface testservice {
/**
* 測試發消息
* @param name
* @return
*/
public string sayhello(string name);
}
注意：這個項目最終打包成jar檔案，直接maven引入到另外兩個項目中

stringbuffer sb = new stringbuffer();
sb.append("dubbo:").append(testservice.sayhello(name));
return sb.tostring();
}
dubbo-consumer終打包成dubbo-consumer.war放在tomcat或其他容器中運作。

}
注意：這裡作為服務提供者名稱為test_provider，注釋很詳細，就不一一介紹了，這個項目最終打包成dubbo-service.war放在tomcat或其他容器中運作
好了，經過這麼配置之後，我們的項目編碼配置部分就大功告成了!
maven編譯下三個項目，将dubbo-provider和dubbo-consumer放到tomcat容器中，啟動tomcat容器！ 出錯啦！ 為啥容器不起來！那是因為我們還少了主要的一步，那就是配置啟動zookeeper，不然dubbo去zookeeper注冊中心暴露服務位址不成功啦！
四、配置啟動zookeeper
最後要啟動zookeeper，關于zookeeper的安裝配置，可以參考：http://blog.csdn.net/tototuzuoquan/article/details/54003140
啟動zookeeper !
再次啟動tomcat容器，是不是就成功啦！我們來通路下http://192.168.106.80:8080//dubbo-consumer/test.action?name=toto，看下傳回結果是不是正确啦！
