when i test dubbo rest protocol, i configure like this according the office
website
```
<dubbo:application name="dubbo-rest"/>
<!--<dubbo:registry address="zookeeper://127.0.0.1:2181"/>-->
<!-- 用rest协议在8080端口暴露服务 -->
<dubbo:protocol name="rest" port="8081" server="tomcat"/>
<!-- 声明需要暴露的服务接口 -->
<dubbo:service interface="com.boot.dubbo.CustomerService"
ref="customerService"/>
<!-- 和本地bean一样实现服务 -->
<bean id="customerService" class="com.boot.dubbo.CustomerServiceImpl" />
```
but the error occur like this
```
java.lang.IllegalStateException: No such any registry to export service in
provider 172.19.6.61 use dubbo version 2.6.2, Please add <dubbo:registry
address="..." /> to your spring config. If you want unregister, please set
<dubbo:service registry="N/A" />
