可分页 - 按多个表中的值排序

Question

我正在编写一个从多个表中收集数据的本机查询。我还需要可分页并按联盟排序。不幸的是，Sort 立即“粘住”了第一个没有给定联盟的表的地址。是否可以动态排序和分页？我试图传递一个名称后跟“order by”的字符串，但hibernate忽略了它。

@Query(value = "SELECT pt.id as id, pt.work as workplace ,bo.virtualName as title, bo.creationDate as date FROM t_projecttemplate pt JOIN t_objecttowork ot on pt.id=ot.id JOIN t_objectplus bo on ot.id=bo.id where bo.deleted=false and bo.parent_id=?1", nativeQuery = true)
List<Map<String,Object>> getObjects (Long parentId, Pageable pageable); //want to sort by title, hibernate sticks immediately "pt."

Answer 1

当您调用getObjects 并将Pageable 传递给它时（例如PageRequest），它有一个sort 参数。所以你可以创建类似的东西：

Pageable myPage = PageRequest.of(0, 10, Sort.Direction.ASC, "title");
getObjects(parentId, myPage);
