dubbox消费者启动成功，却无法连接注册中心
使用dubbox作为服务提供端很好实现，因为git的说明和网上有很多的例子可供参考，但是消费端都一笔带过，简单得很，初学者往往以为只要配置如下3样东西就够了：
<?xml version="1.0" encoding="UTF-8"?>
<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"
xmlns:context="http://www.springframework.org/schema/context"
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 http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd"> <context:annotation-config /> <!-- 消费方应用信息，用于计算依赖关系 -->
<dubbo:application name="zr_consumer" /> <dubbo:registry address="zookeeper://127.0.0.1:2181" /> <!-- 消费者接口 -->
<dubbo:reference id="mobileZoneResourceService"
interface="com.inspur.zoneresource.api.MobileZoneResourceService" /> </beans>
很多例子会写个main方法读取上面这个配置文件，然后调用里面mobileZoneResourceService这个bean里的方法，然后就没了。但我们消费端一般是提供给外部用的，而不是用来写测试类用的。而且这里有个问题：不会到zookeeper注册中心去把消费端注册上去，虽然启动是不会报错的：

消费端引入服务端接口的目的就是为了调用，所以这里应该还有一个bean，用来使用引入的接口：
<!-- 对外control -->
<bean id="mobileZoneResourceController"
class="com.inspur.zoneresource.consumer.control.MobileZoneResourceController" />
此时我们可以看到消费端已经去找zookeeper注册了，但这里我本地没有启动zk，所以会报连接超时：
