Can I use `data class`es for JPA Entities having equals only on id and the other using val somehow? In order to generate equals() only of id it has to be the only argument in the primary constructor.

@Entity
data class Term(
        @Id
        val id: UUID,

        val name: String
) {

    val definition: Definition = Definition.DEFAULT

    constructor(id: UUID, name: String, definition: Definition) : this(id, name) {
        this.definition = definition
    }
}

I think I'd like to do someting like this …

Maybe just move id from constructor to body? Not perfect, of course, but it’s the only way to exclude id from equals/hashcode
