dubbo spring bean id冲突

service-security-provider应用有provider和consumer配置文件

其中secutrity-consumer引用两个服务

	 <dubbo:reference interface="cn.ce.best.member.service.KaUserService" id="kaUserService" init="true"/> 
	 <dubbo:reference interface="cn.ce.best.member.service.KaMenuService" id="kaMenuService" init="true"/>

这两个服务是另一个应用service-member-provider提供的，代码如下

    <dubbo:service interface="cn.ce.best.member.service.KaUserService" ref="kaUserService"/>
    <dubbo:service interface="cn.ce.best.member.service.KaMenuService" ref="kaMenuService"/>

启动service-security-provider报如下错误（已排除serviceImpl 的id重复）

 我好像知道问题了 duobbo应用依赖其它应用服务时，是不是只需要depence api吧，我把实现类也depence进去乐，是不是冲突了？是因为我把其他提供服务的dubbo应用的实现类也依赖进工程里了，导致ID冲突
