Creating Pagination in Spring Data JPA

Question

I am trying to implement pagination feature in Spring Data JPA. I am referring this Blog My Controller contains following code :

 @RequestMapping(value="/organizationData", method = RequestMethod.GET)
  public String list(Pageable pageable, Model model){
    Page<Organization> members = this.OrganizationRepository.findAll(pageable);
    model.addAttribute("members", members.getContent());
    float nrOfPages = members.getTotalPages();
    model.addAttribute("maxPages", nrOfPages);
    return "members/list"; 
  }

My DAO is following :

@Query(value="select m from Member m", countQuery="select count(m) from Member m")
  Page<Organization> findMembers(Pageable pageable);

I am able to show first 20 records, how do I show next 20??? Is there any other pagination example that I can refer??

Solution 1

I've seen similar problem last week, but can't find it so I'll answer directly.

Your problem is that you specify the parameters too late. Pageable works the following way: you create Pageable object with certain properties. You can at least specify:

1. Page size,
2. Page number,
3. Sorting.

So let's assume that we have:

PageRequest p = new PageRequest(2, 20);

the above passed to the query will filter the results so only results from 21th to 40th will be returned.

You don't apply Pageable on result. You pass it with the query.

Edit:

Constructors of PageRequest are deprecated. Use Pageable pageable = PageRequest.of(2, 20);

Solution 2

The constructors of Pageable are deprecated, use of() instead:

Pageable pageable = PageRequest.of(0, 20);

Note: Index is zero-based page index.

new PageRequest() constructor is deprecated

@J3ernhard it wasn't when this answer was prepared.

@xenteros that's right, further information about PageRequest: stackoverflow.com/q/44848653/4121281

how to set page size unlimited?

@SandeepKumar what do you mean, by setting the unlimited page size?

I was writing a wrapper on top of an existing paginated API to fetch all record, I did it by passing Integer.Max_Value.

PageRequest p = new PageRequest(2, 20); can't be passed to spring data

This doesn't exist in my version of spring, how can I create a peageable object to limit the query to 1?

Use PageRequest.of instead of constructor
