Hi,

We have an application that has been built using the Hibernate API, most of our queries are built upon 'session.createCriteria'.

The decision has been made to inject a javax.persistence.EntityManager into the DAOs and our queries have to be made from that.

Rather than rewriting about 100 queries all in one go to use the JPA criteria API is there an easier way to get the hibernate session object to create the org.hibernate.Criteria?

Thanks

Have you tried ?

Hi,

you can inject sessionFactory class in base class, and add methods below to your base object.Reuse methods in childs.



@Autowired
private SessionFactory sessionFactory;

public void setSessionFactory(SessionFactory sessionFactory) {
this.sessionFactory = sessionFactory;
}
protected Criteria criteria(Class clasz){
return session().createCriteria(clasz);
}
protected Session session(){
return getSessionFactory().getCurrentSession();
}

protected Session open(){
return getSessionFactory().openSession();
}
protected org.hibernate.Query createQuery(String queryStr){
org.hibernate.Query query = session().createQuery(queryStr);
return query;
}
protected org.hibernate.SQLQuery createSQLQuery(String queryStr){
org.hibernate.SQLQuery query = session().createSQLQuery(queryStr);
return query;
}
