问使用Scala反射查找重载方法

EN

import scala.reflect.runtime.universe._

object Example {

  class Something {
    def printIt(s1: String,s2: String) {println(s1 + s2) }
    def printIt(s: Int) { println(s) }
    def printIt(s: String) {println(s) }
    def printInt(i: Int) { println(i) }
    def printInt(i: String) { println(i) }
  }

  def main(args: Array[String]): Unit = {

    val r = new Something()

    val mirror = runtimeMirror(getClass.getClassLoader)
    val instanceMirror = mirror.reflect(r)
    val symbols = mirror.typeOf[r.type].decl(TermName("printInt")).asMethod

  }
}

Exception in thread "main" scala.ScalaReflectionException: value printInt encapsulates multiple overloaded alternatives and cannot be treated as a method. Consider invoking `<offending symbol>.asTerm.alternatives` and manually picking the required method
