Question

我有以下课程：

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

当我打电话/书籍时，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（虽然分页有效，没有下一个，上一个链接，也没有任何＆＃34;数＆＃34;字段）

我应该添加什么才能获得与/ books响应相同的HATEOAS体验？

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

我收到了这个回复：

Answer 1

我认为您的存储库应该返回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);
}

PagingAndSortingRepository分页信息
