Detachedcriteria paging projection cancel aggregation Conditions

This problem has plagued me for a long time. After the total number of rows is queried each time, the object information cannot be queried during the query, even if setprojectinos is null, however, the query result is of the List <object []> type when associated.

That is to say, there is still a problem with detachedcriteria. I cannot tell the specific reason, but this is also a solution. I hope it will be helpful to everyone,

In this way, detachedcriteria can be encapsulated to query the total number of rows under the paging condition,
