PagingAndSortingRepository分頁信息

Question

我有以下類：

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

當我打電話/書籍我得到很好的分頁信息，但findByTitle方法我沒有得到任何分頁信息（雖然分頁作品，沒有下一個，prev鏈接或任何「計數」字段）

我應該添加什麼以獲得與/ books響應相同的HATEOAS體驗？

當我打電話 http://127.0.0.1:8888/books/search/findByTitle?title=bc&page=0

我得到這樣的迴應：

我想你的版本庫應該返回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); 
}
