Class AliasToBeanResultTransformer
java.lang.Object
org.hibernate.transform.BasicTransformerAdapter
org.hibernate.transform.AliasedTupleSubsetResultTransformer
org.hibernate.transform.AliasToBeanResultTransformer
- All Implemented Interfaces:
- Serializable, ResultTransformer, TupleSubsetResultTransformer
public class AliasToBeanResultTransformer
- extends AliasedTupleSubsetResultTransformer
Result transformer that allows to transform a result to
a user specified class which will be populated via setter
methods or fields matching the alias names.
List resultWithAliasedBean = s.createCriteria(Enrolment.class)
.createAlias("student", "st")
.createAlias("course", "co")
.setProjection( Projections.projectionList()
.add( Projections.property("co.description"), "courseDescription" )
)
.setResultTransformer( new AliasToBeanResultTransformer(StudentDTO.class) )
.list();
StudentDTO dto = (StudentDTO)resultWithAliasedBean.get(0);
