Simple Web Framework #1: Create a basic router

My:
import scala.collection.mutable.ListBuffer

class Router {

  class Info(Route: String, Http: String, fun: ()=>String)
  {
    var route = Route
    var http = Http
    var message=fun()
    override def equals(obj: Any): Boolean ={
      obj match{
        case obj: Info => route.equals(obj.route) && http.equals(obj.http)
        case _ => false
      }
    }
    override def hashCode: Int = {
      var result = 1
      result = 31 * result + (if (route == null) 0 else route.hashCode)
      result = 31 * result + (if (http == null) 0 else http.hashCode)
      result
    }

    override def toString: String = message
  }

  var list = new ListBuffer[Info]

  def bind(route: String, http: String, fun: ()=>String):Unit=
  {
      if(list.contains(new Info(route, http, ()=>"")))
        {
          list.update(list.indexOf(new Info(route, http, fun)), new Info(route, http, fun))
        }
      else
        list.append(new Info(route, http, fun))

  }

  def runRequest(route:String, http: String):String={

    if(list.contains(new Info(route, http, ()=>""))){
      list.filter(x=>x.equals(new Info(route, http, ()=>""))).head.toString
    }
    else
      "Error 404: Not Found"
  }
}

Other:
class Router {

  private val routes = collection.mutable.Map[(String, String), () => String]()

  def bind(url: String, method: String, action: () => String): Unit =
    routes.update((url, method), action)

  def runRequest(url: String, method: String): String =
    routes.getOrElse((url, method), () => "Error 404: Not Found")()
}
