PagingAndSortingRepository 分页信息

Question

我有以下 class:

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

当我调用 /books 时，我得到了很好的分页信息，但是使用 findByTitle 方法我没有得到任何分页信息（尽管分页有效，没有下一个，上一个链接，也没有任何 "count" 字段）

我应该添加什么才能获得与 /books 响应相同的 HATEOAS 体验？

当我打电话 http://127.0.0.1:8888/books/search/findByTitle?title=bc&page=0

我收到这样的回复：

    "books" : [ {

Answer 1

我认为您的存储库应该 return org.springframework.data.domain.Page 而不是 List。

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