Scala反射调用object

和反射class不同,反射class和java反射一样,object是静态代码块模式的单例,Scala 反射的核心是 scala.reflect.runtime.universe:代码如下:

object:
 

object TargetObject{
  def test1(name:String):String = {
    println("11111111")
    "1111"
  }
}

反射调用:
反射 Scala object 核心是通过 staticModule 获取 ModuleMirror:

object MyTest {

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

    import scala.reflect.runtime.universe
    val classMirror = universe.runtimeMirror(getClass.getClassLoader)
    val staticMirror = classMirror.staticModule("xxx.xxx.TargetObject")
    val moduleMirror = classMirror.reflectModule(staticMirror)
    val objectMirror = classMirror.reflect(moduleMirror.instance)
    val sayHelloSymbol = moduleMirror.symbol.typeSignature.member(universe.TermName("test1")).asMethod
    val value = objectMirror.reflectMethod(sayHelloSymbol)("yege")
    println(value)

  }

}
