Spring Data: limit result for custom query

Viewed 11241

In my Spring Data repository I (have to) use custom queries using the @Query annotation. I know I can limit the number of results in a named query like that

Iterable<Person> findFirst5OrderByLastName()

or that it is possible to limit the number of results by passing a pageable like that

Iterable<Person> findByLastName(String lastName, Pageable pageable)

But is it possible to achieve the same when using a custom @Query annotation?

TIA

EDIT

as I see my question is a little confusing, some clearification: What I want is to limit the number of the results I get, when using a custom query, so that I neither

1) need to specify the result-size through a pageable

2) need to use a named query to specify the result-size

In fact I want the limitation of the number of results to be completely transparent when invoking method (hence not passing a Pageable) and to not rely on the naming-scheme of Spring Data (as the meaning/function of the method is best conveyed through a custom name)

I would suggest to add "By" but without parameter, it would work:

List<Person> findTop100By();

Hello you can try this

@Query("...")
List<YourDTO>getData(Pageable pageable)

In your serviceImpl

    List<YourDTO> getData(){
    int limit=10;
    Pageable pageable = PageRequest.of(0, limit);
    return this.repo.getData(pageable);
}

You should avoid nativeQuery
