四個步驟
1 搭建zookeeper消息中心
2 搭建dubbo服務端代碼
3 寫dubbo用戶端代碼
4 dubbo提供的dubbo-admin-2.5.4.war 管理控制台
一，搭建zookeeper
1 下載下傳zookeeper安裝檔案
zookeeper-3.3.6.tar.gz
這裡提供一個百度網盤的下載下傳位址http://pan.baidu.com/s/1gexxfvP
2 執行指令 tar zxvf zookeeper-3.4.6.tar.gz 解壓,
3 到 zookeeper-3.3.6/conf 目錄下
把zoo_sample.cfg 複制一份為zoo.cfg,作為預設配置檔案
4 配置說明
tickTime：這個時間是作為 Zookeeper 伺服器之間或用戶端與伺服器之間維持心跳的時間間隔，也就是每個 tickTime 時間就會發送一個心跳。
dataDir：顧名思義就是 Zookeeper 儲存資料的目錄，預設情況下，Zookeeper 将寫資料的日志檔案也儲存在這個目錄裡。
clientPort：這個端口就是用戶端連接配接 Zookeeper 伺服器的端口，Zookeeper 會監聽這個端口，接受用戶端的通路請求。
我的配置: 端口2181是預設配置
5 在zookper-3.3.6/bin目錄下執行
./zkServer.sh start 啟動zookeeper
6 驗證zookeeper是否啟動
使用netstat -lpn | grep 2181
如果有端口号, 說明已經啟動
1，pom.xml
Xml代碼

3,spring和dubbo配置檔案
<beans:beans xmlns="http://www.springframework.org/schema/mvc"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:beans="http://www.springframework.org/schema/beans"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd
http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">
<!-- Handles HTTP GET requests for /resources/** by efficiently serving up static resources in the ${webappRoot}/resources directory -->
<resources mapping="/resources/**" location="/resources/" />
<!-- Enables the Spring MVC @Controller programming model -->
<annotation-driven ></annotation-driven>
<!--spring 自動掃描com.zhang下邊的所有類 -->
<context:component-scan base-package="com.zhang" />
<context:property-placeholder location="classpath:config.properties" />
<!-- 自定義配置Service -->
<beans:bean id="sayHelloService" class="com.zhang.service.demoImpl"/>
</beans:beans>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:dubbo="http://code.alibabatech.com/schema/dubbo"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://code.alibabatech.com/schema/dubbo
http://code.alibabatech.com/schema/dubbo/dubbo.xsd
">
<!-- 系統項目名 -->
<dubbo:application name="DubboDemo" />
<!-- 注冊中心 -->
<dubbo:registry protocol="zookeeper" address="${able_zookeeper}" />
<!-- 是否納入調用統計報表（可選） -->
<dubbo:monitor protocol="registry"/>
<!-- 協定 -->
<dubbo:protocol name="dubbo" port="31581" />
<!-- 服務者與消費者的預設配置 -->
<!-- 延遲到Spring初始化完成後，再暴露服務,服務調用逾時設定為6秒,逾時不重試 -->
<dubbo:provider delay="-1" timeout="6000" retries="0"/>
<dubbo:consumer timeout="6000" retries="0"/>
</beans>
<dubbo:service interface="com.zhang.service.demo" ref="sayHelloService" timeout="3000" protocol="dubbo"/>
config.properties
Java代碼
#able_zookeeper
able_zookeeper=192.168.50.42:2181
4,java代碼 一個接口一個實作類
package com.zhang.service;
public interface demo {
public String sayHello();
}
public class demoImpl implements demo {
@Override
public String sayHello() {
return "hello";
}
1，pom.xml和web.xml，config.properties配置檔案和DubboServer配置一樣
2，增加一個消費者配置檔案applicationContext-dubbo-consumer.xml，注：這裡需要把服務提供者的jar包打入到用戶端，打接口就可以
<strong><?xml version="1.0" encoding="UTF-8"?>
http://code.alibabatech.com/schema/dubbo/dubbo.xsd">
<dubbo:reference id="demo" interface="com.zhang.service.demo" check="false" protocol="dubbo"/>
</beans> </strong>
3，使用
<strong>package com.zhang.contr;
import org.springframework.beans.factory.annotation.Autowired;
public class test {
@Autowired
private com.zhang.service.demo demo;
public String testD(){
return demo.sayHello();
</strong>
war包下載下傳位址：http://pan.baidu.com/s/1i4xZamD
把這個war包放到tomcat的webapps目錄下
1 修改tomcat的端口号不要和其他服務沖突.
2 修改 WEB-INF 下的dubbo.properties檔案
3 啟動tomcat,通路.
