Use Projections to specify which columns you would like to return

Example

SQL Query

SELECT user.id, user.name FROM user;

Hibernate Alternative 

Criteria cr = session.createCriteria(User.class)
 .setProjection(Projections.projectionList()
 .add(Projections.property("id"), "id")
 .add(Projections.property("Name"), "Name")) .setResultTransformer(Transformers.aliasToBean(User.class));

 List list = cr.list();
