Java 8 adds a whole new Date & Time API that is a significant improvement over java.util.Date, java.util.Calendar, AND Joda types. It would be fantastic if Hibernate 4.2.x or at least 4.3.x could support these datatypes. Is there a plan in place to make this happen? Doing so could be accomplished (through reflection) without compiling Hibernate against Java 8.

In particular, it would be great to see the following classes supported natively without the user having to do anything other than annotate with @Temporal:

java.time.Instant
java.time.LocalDate
java.time.LocalDateTime
java.time.LocalTime
java.time.OffsetDateTime
java.time.OffsetTime
java.time.ZonedDateTime

Also, it would be great to have some kind of support for these types as well:

java.time.Duration (as a string column or a numeric column)
java.time.Period (as a string column or a numeric column)
java.time.YearMonth (as a string column, or as a year-month column if the dialect supports)
java.time.MonthDay (as a string column, or as a month-day column if the dialect supports)
java.time.ZodeId (as a string column)

Thoughts? Is this already happening?

I would also very, very much like this functionality.

There is a Jira to address this: https://hibernate.atlassian.net/browse/HHH-8844.

Vote for that issue if it is important to you.

Hibernate 5.0.0 CR2 supports Java 8 Date & Time with the separate module "hibernate-java8....".

But how do we implement this in a class like this:

@Column(name = "date", length = 29)
@Type(type = "de.programm.classes.ZonedDateTimeUserType")
public ZonedDateTime getDate() {
return this.date;
}

while using java 8 syntax?


Best regards!
