dubbox消費者啓動成功，卻沒法鏈接註冊中心

　　使用dubbox做爲服務提供端很好實現，由於git的說明和網上有不少的例子可供參考，可是消費端都一筆帶過，簡單得很，初學者每每覺得只要配置以下3樣東西就夠了：html

<?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 />

    <!-- 消費方應用信息，用於計算依賴關係 -->
    <dubbo:application name="zr_consumer" />

    <dubbo:registry address="zookeeper://127.0.0.1:2181" />

    <!-- 消費者接口 -->
    <dubbo:reference id="mobileZoneResourceService"
        interface="com.inspur.zoneresource.api.MobileZoneResourceService" />

</beans>

　　不少例子會寫個main方法讀取上面這個配置文件，而後調用裏面mobileZoneResourceService這個bean裏的方法，而後就沒了。但咱們消費端通常是提供給外部用的，而不是用來寫測試類用的。並且這裏有個問題：不會到zookeeper註冊中心去把消費端註冊上去，雖然啓動是不會報錯的：java

　　消費端引入服務端接口的目的就是爲了調用，因此這裏應該還有一個bean，用來使用引入的接口：git

    <!-- 對外control -->
    <bean id="mobileZoneResourceController"
        class="com.inspur.zoneresource.consumer.control.MobileZoneResourceController" />

　　此時咱們能夠看到消費端已經去找zookeeper註冊了，但這裏我本地沒有啓動zk，因此會報鏈接超時：web
