error: No validator could be found for type: java.time.LocalDate

Question

Actually the issue to refer to is HV-874. Hibernate Validator 5.2.x does add support for some of the new Java 8 date/time types. I should stress "some" in this context. In particular LocalDate is not supported. The Javadocs of LocalDate says:

This class does not store or represent a time or time-zone. Instead, it is a description of the date, as used for birthdays. It cannot represent an instant on the time-line without additional information such as an offset or time-zone.

Without an instant on the timeline it is not possible to say if a given date is in the part or future. First by attaching a timezone it would be possible to state and answer this question.

If you still think it makes sense in your use case to use the Past and @Future constraints for LocalDate you can always implement your own ConstraintValidator for LocalDate and register it via XML using a constraint-definition element in a constraint mapping file as seen here.

If you are using Hibernate Validator 5.2, you can also use the Java ServiceLoader approach to register additional ConstraintValidator implementations - see ConstraintDefinitionContributor. The latter is for now a Hibernate Validator specific feature.
