Spring找不到bean

[frost_pig]

场景：SSM整合下，有名为RPCMonAlarmRuleDaoDao的接口，在包com.lss.owl.common.dao下，
配置文件是自动扫描包的（<context:component-scan base-package="com.jumei.owl.**.service, com.lss.**.**.dao" />）

Tomcat启动报错信息：
Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'com.lss.owl.common.dao.RPCMonAlarmRuleDao' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}

Service的注解声明如下,其中ProjectAlarmDao 和 RPCMonAlarmRuleDao 是在同一包下
@Autowired
private ProjectAlarmDao alarmUproDao; （能找到bean）

@Autowired
private RPCMonAlarmRuleDao rpcMonAlarmRuleDao;（不能找到bean）


ProjectAlarmDao如下：
package com.lss.owl.common.dao;

import java.util.List;

import com.lss.owl.common.domain.AlarmUser;
import com.lss.owl.common.domain.ProjectAlarm;

public interface ProjectAlarmDao{
int deleteByPrimaryKey(Long userId,Long project_id);

int insert(ProjectAlarm record);

int insertSelective(ProjectAlarm record);
}


RPCMonAlarmRuleDao如下：
package com.lss.owl.common.dao;
import java.util.List;

import org.springframework.stereotype.Repository;

import com.lss.owl.common.domain.RPCMonAlarmRule;

@Repository (这个地方不使用@Repository同样会报找不bean的错误)
public interface RPCMonAlarmRuleDao{

int deleteByPrimaryKey(Integer id);

int insert(RPCMonAlarmRule record);

int insertSelective(RPCMonAlarmRule record);

}

@Repository ("rpcMonAlarmRuleDao")
