How to map array database type to kotlin

Question

I have this entity

@Entity
@Table(name = "foo")
class Foo(
    @Column(name = "bar_ids", columnDefinition = "uuid[]")
    val barIds: Array<UUID>,
) {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    val id: Long = 0
}

which gives me

'Basic' attribute type should not be 'UUID[]'

How to define an array datatype?

Answer 1

I think, this is the way to go

import io.hypersistence.utils.hibernate.type.array.EnumArrayType
import io.hypersistence.utils.hibernate.type.array.internal.AbstractArrayType

@Type(
      value = EnumArrayType::class,
      parameters = [Parameter(name = AbstractArrayType.SQL_ARRAY_TYPE, value = "uuid")]
    )
    @Column(name = "bar_ids", columnDefinition = "uuid[]")
    val barIds: List<UUID>,
