In my app i need to search an order by his creation_date.
In my entity, the type of the creationDate field is java.time.Instant.



In my class ManualOrderSpecification i need to check the creation_date.



I would like to compare the date of creation without the hours or with the same hour (0 hour for example).



My code :



 if (searchBean.getCreatedDate() != null) 
Instant createdInstantFromForm = ZonedDateTime.of(searchBean.getCreatedDate(), LocalTime.of(0, 0, 0, 0), ZoneId.systemDefault()).toInstant();
p.getExpressions().add(criteriaBuilder.equal(root.get(ManualOrder_.createdDate), createdInstantFromForm ));



Of course it doesn't work because i compare the same date but with different hours, 0 hour to another hours.
How can i force to compare to a localdate
or
can i force to 0 hours the root.get(ManualOrder_.createdDate) attribute ?



Many thanks
