Has anyone used Hibernate successfully with Kotlin? Checked #hibernate but the channel seems pretty dead.

I have used it through Spring framework.

[Jeff Gulbronson]

Have you used abstract classes at all?

[kenji_otsuka]

@Jeff Gulbronson for what? Entity?

[Stefan Peterson]

I have. Do you have a more specific question?

+1 for specific. I`m using data classes a lot(as entities) with SB2(hibernate under the hood) - only issue was MappedSuperClass for some common fields. Other things work as usual

[Jeff Gulbronson]

Sorry about that! I have a class like so

@MappedSuperclass
open class TimestampedDbEntity {
  @Column(updatable = false)
  lateinit var createdAt: DateTime

  @Column
  lateinit var updatedAt: DateTime
}

But it seems that the variables aren’t being initialized properly when loaded from the database.
