如何在使用json4s时设置杰克逊解析器功能？

import org.json4s.DefaultFormats
import org.json4s.jackson.JsonMethods

implicit val formats: DefaultFormats = DefaultFormats.withDateFormat("yyyy-MM-dd")

val json = """{"date": "2022-01-01"}"""
val parsedJson = JsonMethods.parse(json)
val date = (parsedJson \ "date").extract[Date]

import org.json4s.DefaultFormats
import org.json4s.jackson.JsonMethods

implicit val formats: DefaultFormats = DefaultFormats.withIgnoreUnknownFields(true)

val json = """{"name": "John", "age": 30, "unknownField": "value"}"""
val parsedJson = JsonMethods.parse(json)
val name = (parsedJson \ "name").extract[String]
val age = (parsedJson \ "age").extract[Int]

import org.json4s.DefaultFormats
import org.json4s.FieldSerializer
import org.json4s.jackson.JsonMethods

case class Person(firstName: String, lastName: String)

implicit val formats: DefaultFormats = DefaultFormats.withFieldSerializer(
  FieldSerializer[Person](renameTo("firstName", "first_name"))
)

val json = """{"first_name": "John", "lastName": "Doe"}"""
val parsedJson = JsonMethods.parse(json)
val person = parsedJson.extract[Person]
val firstName = person.firstName
val lastName = person.lastName
