+### Introduction
 
 examples是基于dubbogo的实现的代码示例,目前提供user-info一个例子。examples/client 是一个 go client,借鉴java的编译思路,提供了区别于一般的go程序的而类似于java的独特的编译脚本系统。

 *从这个程序可以看出dubbogo client程序(user-info/client) 如何调用 java(dubbo) server的程序( user-info/java-server)的。*
 
 **Attention**: 测试的时候一定注意修改配置文件中服务端和zk的ip&port。

+### QA List
+
+#### 1 Unsupported protocol jsonrpc
+
+问题描述: 用java写的dubbo provider端程序如果遇到下面的错误:
+
+	 java.lang.IllegalStateException: Unsupported protocol jsonrpc in notified url:   
+	
+	 jsonrpc://116.211.15.189:8080/im.ikurento.user.UserProvider?anyhost=true&application=token-dubbo-p&default.threads=100&dubbo=2.5.3…
+	
+	 from registry 116.211.15.190:2181 to consumer 10.241.19.54, supported protocol: [dubbo, http, injvm, mock, redis, registry, rmi, thrift]
+
+错误原因:provider端声明使用了jsonrpc,所以所有的协议都默认支持了jsonrpc协议。
+
+解决方法:服务需要在dubbo.provider.xml中明确支持dubbo协议,请在reference中添加protocol="dubbo",如:
+
+    <dubbo:protocol name="dubbo" port="28881" />
+    <dubbo:protocol name="jsonrpc" port="38881" server="jetty" />
+    <dubbo:service id="userService" interface="im.ikurento.user.UserProvider" check="false" timeout="5000" protocol="dubbo"/>
+
+ 	<dubbo:service id="userService" interface="im.ikurento.user.UserProvider" check="false" timeout="5000" protocol="jsonrpc"/>
+
+与本问题无关,补充一些消费端的配置:
+
+    <dubbo:reference id="userService" interface="im.ikurento.user.UserService" connections="2" check="false">
+    	<dubbo:method name="GetUser" async="true" return="false" />
+ 	</dubbo:reference>
+
+#### 2 配置文件
+
+dubbogo client端根据其配置文件client.toml的serviceList来watch zookeeper上相关服务,否则当相关服务的zk provider path下的node发生增删的时候,因为关注的service不正确而导致不能收到相应的通知。
+
+所以务必注意这个配置文件中的serviceList与实际代码中相关类的Service函数提供的Service一致。
+
+#### 3 其他注意事项
+- a. dubbo 可以配置多个 zk 地址;
+- b. 消费者在 dubbo 的配置文件中相关interface配置务必指定protocol, 如protocol="dubbo";
+- c. java dubbo provider提供服务的method如果要提供给dubbogo client服务,则method的首字母必须大写;
