你可以创建你自己的序列化器模型，使用：
进口：

import kotlinx.serialization.ExperimentalSerializationApi
import kotlinx.serialization.KSerializer
import kotlinx.serialization.Serializable
import kotlinx.serialization.Serializer
import kotlinx.serialization.encoding.Decoder
import kotlinx.serialization.encoding.Encoder

@Serializer(forClass = LocalDate::class)
object DateSerializer : KSerializer<LocalDate> {
    private val formatter = DateTimeFormatter.ISO_LOCAL_DATE

    override fun serialize(encoder: Encoder, value: LocalDate) {
        encoder.encodeString(value.format(formatter))
    }

    override fun deserialize(decoder: Decoder): LocalDate {
        return LocalDate.parse(decoder.decodeString(), formatter)
    }
}

然后使用@Serializabe类描述符，例如：

@Serializable(with = DateSerializer::class)
    val startDate: LocalDate,
    @Serializable(with = DateSerializer::class)
    val endDate: LocalDate
