使用scala将map转为case class 的类

case class Testtt(name:String,age:String)
object TestDay {
  def main(args: Array[String]): Unit = {

    val map = new mutable.HashMap[String, String]()

    map.put("name","小明")
    map.put("age","20")

    println(createCaseClass[Testtt](map))

  }

  //将map转为实体的case class
  def createCaseClass[T](vals: mutable.HashMap[String, String])(implicit cmf: ClassManifest[T]) = {
    val ctor = cmf.erasure.getConstructors.head

    val args = cmf.erasure.getDeclaredFields.map(f => vals.getOrElse(f.getName, null))
    ctor.newInstance(args: _*).asInstanceOf[T]
  }
}
