hibernate - Hibernate 标准：使用 TransferObject 进行投影

Question

如何将下面的 HQL 代码转换为 Hibernate Criteria 查询？

SELECT
    new com.project.to.PersonTO(
        person.firstName,
        person.lastName
    )
FROM
    Person person

Answer 1

试试下面： -

Criteria criteria = session.createCriteria(Person.class);
criteria.setProjection(Projections.projectionList().add(Projections.property("firstName"), "firstName") .add(Projections.property("lastName"), "lastName"))
                    .setResultTransformer(new AliasToBeanResultTransformer(PersonTO.class));
