No unique bean of type [] is defined

这是错误信息
No unique bean of type [com.home.web.AbsCrudDaoImpl] is defined: expected single matching bean but found 3: [agoodsCategoryDao, agoodsInfoDao, generateDao]
我是写了一个公共的dao类，然后继承这个类，下面是类一些的代码：
public class AbsCrudDaoImpl extends HibernateDaoFactory{

public Object get(Class clazz, Serializable id) throws DataAccessException {
    return getHibernateTemplate().get(clazz, id);
}

public Object load(Class clazz, Serializable id) throws DataAccessException {
    return getHibernateTemplate().load(clazz, id);
}

public Integer save(Object entity) throws DataAccessException {
    return (Integer) getHibernateTemplate().save(entity);
}
....
public class AbsCrudService<DAO extends AbsCrudDaoImpl> {

protected DAO absCrudDao;

public DAO getAbsCrudDao() {
    return absCrudDao;
}

@Resource
public void setAbsCrudDao(DAO absCrudDao) {
    this.absCrudDao = absCrudDao;
}

public Integer save(Object entity) throws DataAccessException {
    return (Integer) absCrudDao.save(entity);
}
....
public class AbsCurdController<Service extends AbsCrudService<?>> {

private static final long serialVersionUID = 1L;

protected Service service;

public Service getService() {
    return service;
}

@Resource
public void setService(Service service) {
    this.service = service;
}

数组没有定义？我也看的一知半解的
