	<!-- 配置包扫描器 -->
	<context:component-scan base-package="cn.demo.service"/>
	
	<!-- 使用dubbo发布服务 -->
	<!-- 提供方应用信息，用于计算依赖关系 -->
	<dubbo:application name="dubbo-demo" />
	<dubbo:registry protocol="zookeeper" address="192.168.1.14:2181" />
	<!-- 用dubbo协议在20880端口暴露服务 -->
	<dubbo:protocol name="dubbo" port="20880" />
	
	<!-- 声明需要暴露的服务接口 -->
	<dubbo:service interface="cn.demo.service.ItemService" ref="itemServiceImpl" timeout="600000"/>
</beans>

3.服务消费者在SpringMVC配置文件中配置

	<context:property-placeholder location="classpath:conf/resource.properties" />
	
	<mvc:annotation-driven />
	<bean
		class="org.springframework.web.servlet.view.InternalResourceViewResolver">
		<property name="prefix" value="/WEB-INF/jsp/" />
		<property name="suffix" value=".jsp" />
	</bean>
	
	<!-- 配置资源映射 -->
	<mvc:resources location="/css/" mapping="/css/**"/>
	<mvc:resources location="/js/" mapping="/js/**"/>
	
	<!-- 引用dubbo服务 -->
	<dubbo:application name="e3-manager-web"/>
	<dubbo:registry protocol="zookeeper" address="192.168.1.14:2181"/>
