PagingAndSortingRepository pagination information

Question

I've the following class:

@RepositoryRestResource(collectionResourceRel = "books", path = "books")
public interface BookRepository extends PagingAndSortingRepository<Book, Long> {
    List<Book> findByTitle(Pageable pageable, @Param("title") String title);
}

When I call /books I get nice pagination information, but with findByTitle method I don't get any pagination information (although pagination works, no next,prev links nor any "count" fields)

What should I add to get the same HATEOAS experience with the /books response?

When I call http://127.0.0.1:8888/books/search/findByTitle?title=bc&page=0

I get this response:

    {
  "_embedded" : {
    "books" : [ {
      "title" : "bc",
      "_links" : {
        "self" : {
          "href" : "http://127.0.0.1:8888/books/4"
        },
        "book" : {
          "href" : "http://127.0.0.1:8888/books/4"
        }
      }
    }, {
      "title" : "bc",
      "_links" : {
        "self" : {

I think your repository should return a org.springframework.data.domain.Page instead of a List.

@RepositoryRestResource(collectionResourceRel = "books", path = "books")
public interface BookRepository extends PagingAndSortingRepository<Book, Long> {
    Page<Book> findByTitle(Pageable pageable, @Param("title") String title);
}

Now that's one step closer, with Page it returned the page statistics (count etc.) but HATEOAS links (next,prev,last) are still missing. :) – EralpB Jan 23 '17 at 13:17

Oh it worked, I must've missed something in my first try, thank you! – EralpB Jan 23 '17 at 13:30
