How to query data out of the box using Spring data JPA by both Sort and Pageable?

Question

I am trying Spring data JPA in my project. I want to know if there is an out-of-the-box API to query data, by both Sort and Pageable. Of course, I know I can write that method myself, I just want to know if there is an out-of-the-box one. My DAO extends JpaRepository, and I found there are the following methods I can invoke:

findAll();
findAll(Pageable pageable);
findAll(Sort sort);

But there is no such method as findAll(Sort sort, Pageable pageable), so I am curious.

Answer 1

There are two ways to achieve this:

final PageRequest page1 = new PageRequest(
  0, 20, Direction.ASC, "lastName", "salary"
);

final PageRequest page2 = new PageRequest(
  0, 20, new Sort(
    new Order(Direction.ASC, "lastName"), 
    new Order(Direction.DESC, "salary")
  )
);

dao.findAll(page1);

As you can see the second form is more flexible as it allows to define different direction for every property (lastName ASC, salary DESC).

Answer 2

Pageable has an option to specify sort as well. From the java doc

PageRequest(int page, int size, Sort.Direction direction, String... properties) 

Creates a new PageRequest with sort parameters applied.

Answer 3

in 2020, the accepted answer is kinda out of date since the PageRequest is deprecated, so you should use code like this :

Pageable page = PageRequest.of(pageable.getPageNumber(), pageable.getPageSize(), Sort.by("id").descending());
return repository.findAll(page);

Answer 4

Spring Pageable has a Sort included. So if your request has the values it will return a sorted pageable.

request: domain.com/endpoint?sort=[FIELDTOSORTBY]&[FIELDTOSORTBY].dir=[ASC|DESC]&page=0&size=20

That should return a sorted pageable by field provided in the provided order.

Answer 5

In my case, to use Pageable and Sorting at the same time I used like below. In this case I took all elements using pagination and sorting by id by descending order:

modelRepository.findAll(PageRequest.of(page, 10, Sort.by("id").descending()))

Like above based on your requirements you can sort data with 2 columns as well.

Answer 6

 public List<Model> getAllData(Pageable pageable){
       List<Model> models= new ArrayList<>();
       modelRepository.findAllByOrderByIdDesc(pageable).forEach(models::add);
       return models;
   }
