FluentQuery allows extending a query specification initially defined by a Example probe or a Querydsl Predicate and fetching the actual result through a functional programming model:
interface PersonRepository extends QuerydslPredicateExecutor<Person> {
<S extends T, R> R findBy(Predicate predicate, Function<FluentQuery.FetchableFluentQuery<S>, R> queryFunction);
}
PersonRepository repo = …;
List<PersonProjection> result = repo.findBy(QPerson.person.name.eq("Walter"), q -> q.sort(Sort.by("lastname")).as(PersonProjection.class).all());
