Why my Pageable API is not working with Spring MVC? - spring

Question

Im implementing an API that is working correctly, but when i use pagitation this is returning nothing.
I have the next code for my repository:
public interface VinetaRepository extends JpaRepository<Vineta, Long> {
List<Vineta> findAllByOrderByCreationdateDesc();
List<Vineta> findByTitulo(String titulo);}
and, when i used the next RequestMapping everthings is ok:
#JsonView(VinetaView.class)
#RequestMapping("/api/vinetas2/")
public List<Vineta> getvinetas2(){
return this.vinetarepository.findAll();
}
but, when i use the pagination, my api is returnin anything:
#JsonView(VinetaView.class)
#RequestMapping(value = "/api/vinetaspage/", method= RequestMethod.GET)
public Page<Vineta> getvinetaspage(Pageable page ){
//This System.out print all the size of my repository
System.out.println(this.vinetarepository.findAll().size());
//This for print the title for my 20 first objects Vineta
for(Vineta v:this.vinetarepository.findAll(page)){
System.out.println(v.getTitulo());
}
// This print 20
System.out.println(this.vinetarepository.findAll(page).getSize());
//This print the page number = 0
System.out.println(page.getPageNumber());
//This print the page size = 20
System.out.println(page.getPageSize());
//Finally, this is not returning nothing
return vinetarepository.findAll(page);
}
With the System out, i can see that the size of my query is correct (20), but nothing is returning.
Both function are using the same Jsonview, so this problem is discarded.

An adapter class (like PageWrapper) would be needed to wrap the Spring Data Page interface as the page interface may lack of features.
public class PageWrapper {
}
