如何在scala中序列化DateTimeFormatter？

import java.io.{ObjectOutputStream, ByteArrayOutputStream, ObjectInputStream, ByteArrayInputStream}
import java.time.format.DateTimeFormatter

class SerializableDateTimeFormatter extends Serializable {
  private val formatter: DateTimeFormatter = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss")

  def getFormatter: DateTimeFormatter = formatter

  // 序列化方法
  def serialize(): Array[Byte] = {
    val outputStream = new ByteArrayOutputStream()
    val objectOutputStream = new ObjectOutputStream(outputStream)
    objectOutputStream.writeObject(this)
    objectOutputStream.close()
    outputStream.toByteArray
  }
}

// 使用示例
val serializableFormatter = new SerializableDateTimeFormatter()
val serializedData = serializableFormatter.serialize()

// 反序列化方法
def deserialize(serializedData: Array[Byte]): SerializableDateTimeFormatter = {
  val inputStream = new ByteArrayInputStream(serializedData)
  val objectInputStream = new ObjectInputStream(inputStream)
  val deserializedObject = objectInputStream.readObject()
  objectInputStream.close()
  deserializedObject.asInstanceOf[SerializableDateTimeFormatter]
}

// 反序列化示例
val deserializedFormatter = deserialize(serializedData)
val formatter = deserializedFormatter.getFormatter
