服务提供者配置文件示例如下：
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:dubbo="http://code.alibabatech.com/schema/dubbo"
xmlns="http://www.springframework.org/schema/beans"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
http://code.alibabatech.com/schema/dubbo http://code.alibabatech.com/schema/dubbo/dubbo.xsd">
<!-- 提供方应用名称, 用于计算依赖关系 -->
<dubbo:application name="dubboprovider"/>
<!-- 使用zookeeper注册中心暴露服务地址 -->
<!-- <dubbo:registry address="zookeeper://192.168.220.100:2181"/> -->
<dubbo:registry protocol="zookeeper" address="192.168.220.100:2181,192.168.220.100:2182,192.168.220.100:2183"/>
<!-- 使用dubbo协议在20880端口暴露服务 -->
<dubbo:protocol name="dubbo" port="20880"/>
<!-- service实现类作为本地的一个bean -->
<bean id="helloDubbo" class="com.zxp.dubbo.serveiceImpl.HelloServiceImpl"/>
<!-- 声明需要暴露的服务接口 -->
<dubbo:service interface="com.zxp.dubbo.HelloService" ref="helloDubbo"/>
</beans>
服务消费者配置文件示例如下：
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:dubbo="http://code.alibabatech.com/schema/dubbo"
xmlns="http://www.springframework.org/schema/beans"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
http://code.alibabatech.com/schema/dubbo http://code.alibabatech.com/schema/dubbo/dubbo.xsd">
<!-- consumer's application name, used for tracing dependency relationship (not a matching criterion),
don't set it same as provider -->
<dubbo:application name="dubboconsumer"/>
<!-- use multicast registry center to discover service -->
<!-- <dubbo:registry address="zookeeper://192.168.220.100:2181"/> -->
<dubbo:registry protocol="zookeeper" address="192.168.220.100:2181,192.168.220.100:2182,192.168.220.100:2183"/>
<!-- generate proxy for the remote service, then demoService can be used in the same way as the
local regular interface -->
<dubbo:reference id="helloService" check="false" interface="com.zxp.dubbo.HelloService"/>
</beans>
将上面的服务提供者，消费者加入spring或springmvc项目，就可以搭建dubbo服务了。
解决Eclipse中不识别dubbo标签引起配置文件报错的问题
在Eclipse中使用dubbo时，会发现Eclipse默认不识别dubbo的标签。虽然不妨碍使用，看着红叉也不舒服，所以还是让Eclipse识别一下dubbo标签。
步骤一：
网上下载 dubbo.xsd，放到任意目录，比如E:eclipseplugins目录下，配置时用得到
步骤二：
在Eclipse中点开Window--Preferences，在弹出的对话框中找到XML--XML Catalog，点击右侧的Add
步骤三：
弹出的对话框中，正确填写Location和key，点击OK ，就配好啦
配置dubbo.xsd文件之后，如下图所示
最后步骤：
选择显示错误的“引入dubbo标签的xml文件”，点击右键,选择 "validate"就ok了，如果不行，关闭文件再打开一次就好了。
Dubbo 管控台搭建
步骤一，下载dubbo-admin项目，打成war部署，或直接现在现成的dubbo-admin-2.6.0.war
步骤二，拷贝dubbo-admin-2.6.0.war到tomcat的ROOT目录，解压即可
步骤三，找到dubbo.properties文件，配置zookeeper服务器地址及账号（默认root就行），如下图
最后，启动tomcat，就可以访问了。账号密码都为root。（另外，要保证zookeeper服务器已经启动，否则链接不上zookeeper,会报错）
