Spring data Page.getTotalElements est incorrect sur la dernière page

salut,

Sur la dernière page, PageImpl.getTotalElements ne renvoie pas le nombre total correct d'éléments.

J'ai besoin de page.getTotalElements () afin d'afficher le nombre total de lignes dans la partie web

avec cette maniere :

Code:

resp.headers.get('X-Total-Count')

,

j'utilise ce code

Code:
