dubbox 消费端服务启动不支持rest协议

提供端服务配置
<dubbo:application name="helllo" /> <!-- 使用zookeeper注册中心暴露服务地址 -->
<dubbo:registry address="zookeeper://192.168.163.131:2181?backup=192.168.163.131:2182,192.168.163.131:2183" />
<dubbo:service interface="com.jt.dubbo.service.CartDubboService" 
ref="cartDubboService" protocol="rest" timeout="10000"/>

<bean id="cartDubboService" class="com.jt.cart.service.CartDubboServiceImpl"/>
消费端服务配置
  <dubbo:application name="hi"/> <dubbo:registry address="zookeeper://192.168.43.135:2181?backup=192.168.43.136:2181,192.168.43.137:2181" />
 
    <dubbo:reference check="false" id="cartDubboService" interface="com.jt.dubbo.service.CartDubboService" timeout="10000"/>
</beans>dubbo-admin 都能正常显示出服务和消费

解决方案 »

  1.   

    对于上述问题，只需要在服务消费端配置引入服务时，设置指定的支持的协议即可，例如下面的标红处<dubbo:reference id="xxxService" interface="cn.xxx.xxx.xxxxService"
                         version="${dubbo.version}" check="false" protocol="dubbo"/>

  3.   

    可能是缺少rest协议相关jar包，消费者加上试试
