求大神解决

我用dubbo+ zookeeper搭建的环境，启动Tomcat老是显示 

Error creating bean with name 'com.bjpowernode.p2p.enterface.LoanInfoService': 

Cannot resolve reference to bean 'loanInfoService' while setting bean property 'ref'; 

到底是什么原因啊。

<!-- dubbo服务的配置 -->
<dubbo:service interface="com.bjpowernode.p2p.enterface.LoanInfoService" ref="loanInfoService"/>
