json字符串,对象互转

1. 定义case class

case class ShockArrayEvent(imei: String, time: Long, gm: List[List[Int]])

2. 转换

import net.liftweb.json._
import net.liftweb.json.Serialization.write

object MyTest {

  def main(args: Array[String]): Unit = {
    implicit val formats: DefaultFormats.type = DefaultFormats
    val json: String = "{\"gimei\": \"861050045442715\", \"gm\": [[124, 119, 1081], [123, 112, 1087]], \"imei\": \"1000007\", \"time\": 1598647456, \"hc\": \"75.2\", \"tc\": \"27.1\"}";
    //JSON字符串转对象
    val event = parse(json).extract[ShockArrayEvent]
    //对象转JSON字符串
    val value = write[ShockArrayEvent](event)
    println(value)
  }
}
