   5. the config of the consumer is :
   <beans xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
          xmlns:dubbo="http://dubbo.apache.org/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-4.3.xsd
          http://dubbo.apache.org/schema/dubbo 
http://dubbo.apache.org/schema/dubbo/dubbo.xsd";>
   
       <dubbo:application name="demo-consumer"/>
   
       <dubbo:consumer cluster="zone-aware"/>
   
       <dubbo:registry id="r1" address="zookeeper://192.168.132.193:2181" 
preferred="true" timeout="25000"/>
   
       <dubbo:registry id="r2" address="zookeeper://192.168.132.194:2181" 
timeout="25000"/>
   
       <dubbo:reference id="demoService" check="false" 
interface="org.apache.dubbo.demo.DemoService" registry="r1,r2"/>
   
   </beans>
   
   
   Does the zone-aware cluster work? Is the config right?
