java - DAO architecture approach:based on HibernateDaoSupport or on EntityManager -

i want manage dao in same way:

1) create 1 base class entity operations save, update, delete, etc.
2) each dao inherits base class , performs base class operations.
3) entities have 1 root.

public abstract basedao { ...    @transactional    public t update(t entity) throws dataaccessexception {        gethibernatetemplate().update(entity);        return entity;    } } ... public memberdao extends basedao { ...    @override    @transactional    public imember update(imember member) throws dataaccessexception {        super.update(member);        return member;    } } 

and there 2 possible way:

1) based on hibernatedaosupport , gethibernatetemplate()
2) based on getentitymanagerfactory().createentitymanager()

main question approach based on hibernatetemplate or on entitymanager - of them better use?

underlying jpa provider in both cases hibernate.
