问题描述
当我尝试在 Mongodb 和 spring boot 中使用 pageable 执行 find near 时遇到一个奇怪的错误。我的收藏有 5 家商店。当我使用以下参数调用该方法时：Page 0 和 Page Size of 5 or below 它可以工作。但是，当我使用等于或大于商店总数的 PageSize 调用它时，我会收到此错误。我注意到当 spring 数据 mongo 在内部调用方法 doCount 时会发生错误，但我不知道是什么错误。

解决方法
伙计们，我解决了这个问题。在我的控制器中，我传递了一个 GeoJsonPoint 作为参数。当我更改为 Point 时，它起作用了。
---- 之前----
GeoPage<StoreDTO> page = storeService.findNearestDtos(dto.getPointsAsGeoJsonPoint(),dto.getGeoDistance(),dto.getPageable());
----- 之后-----
GeoPage<StoreDTO> page = storeService.findNearestDtos(dto.getPointsAsPoint(),dto.getPageable());
