如何在Jetbrains Exposed中添加数组列类型

import org.jetbrains.exposed.dao.IntIdTable
import org.jetbrains.exposed.sql.Column
import org.jetbrains.exposed.sql.Table
import org.jetbrains.exposed.sql.`java-time`.date
import org.jetbrains.exposed.sql.transactions.transaction
import org.jetbrains.exposed.sql.vendors.PostgreSQLDialect

// 定义一个自定义的数组列类型
class ArrayColumnType<T>(private val elementType: Column<T>) : Column<List<T>>(elementType.columnType) {
    override fun sqlType(): String = "${elementType.sqlType()}[]"
    override fun valueFromDB(value: Any): List<T> = when (value) {
        is Array<*> -> value.map { elementType.valueFromDB(it) }
        else -> error("Unexpected value: $value")
    }
    override fun notNullValueToDB(value: Any): Any = when (value) {
        is List<*> -> value.map { elementType.notNullValueToDB(it) }.toTypedArray()
        else -> error("Unexpected value: $value")
    }
}

// 创建一个新的表，并添加一个数组列类型
object MyTable : IntIdTable() {
    val arrayColumn: Column<List<Int>> = registerColumn("array_column", ArrayColumnType(IntegerColumnType()))
}

fun main() {
    // 注册自定义列类型到Exposed框架
    transaction {
        val dialect = PostgreSQLDialect()
        dialect.registerColumnType(MyTable.arrayColumn.columnType)
    }
}
