如何在Scala中使用反射。我正在尝试使用getDeclaredMethod()

import java.lang.reflect._

val clazz: Class[_] = classOf[YourClass]

val method: Method = clazz.getDeclaredMethod("methodName", classOf[ParameterType1], classOf[ParameterType2], ...)

method.setAccessible(true)

val result = method.invoke(instance, arg1, arg2, ...)

import java.lang.reflect._

class YourClass {
  def yourMethod(param: String): Unit = {
    println("Hello, " + param)
  }
}

object Main extends App {
  val clazz: Class[_] = classOf[YourClass]
  val method: Method = clazz.getDeclaredMethod("yourMethod", classOf[String])
  method.setAccessible(true)
  
  val instance = new YourClass()
  val result = method.invoke(instance, "World")
}
