Spring dependency injection and generic class

Spring dependency injection and generic class

Sorry for my English. I can not to do dependency injection for generic
class in spring. Generic class:
abstract class BaseBO<Id, Entity, DAOClass extends DAO<Id, Entity>>
implements BO<Id, Entity, DAOClass> {
DAOClass dao;
public DAOClass getDAO() {
return dao;
}
//...
}
Use generic class:
public class TaskBO extends BaseBO<Long, Task, TaskDAO> implements
BO<Long, Task, TaskDAO> {
}
I want to do dependency injection in a class TaskBO for property TaskDAO.
But I can only to set dependency TaskDAO via a interface DAO for bean
TaskBO:
<bean id="TaskBO" class="com.otv.model.bo.TaskBO">
<property name="DAO" ref="TaskDAO" />
</bean>
<bean id="TaskDAO" class="com.otv.model.dao.TaskDAO">
<property name="sessionFactory" ref="SessionFactory" />
</bean>
How to set dependency injection via class TaskDAO?
