not found: value UADetectorServiceFactory

问题

On the reference of this question, I try the below code in Scala:

import net.sf.uadetector._
def check = Action { implicit request =>
    println(request.headers)
    var parser = UADetectorServiceFactory.getOnlineUpdatingParser();
    println(parser)
    val agent = parser.parse(request.headers.get("User-Agent").getOrElse(""))
    println(agent)
    val which = agent.getUserAgentType(); // this can be ROBOT, BROWSER, etc.
    println(which)
    Ok(write(Map("result" -> true)))
}

and

libraryDependencies += "net.sf.uadetector" % "uadetector-core" % "0.9.16"

but I am getting an error:

not found: value UADetectorServiceFactory

var parser = UADetectorServiceFactory.getOnlineUpdatingParser();

             ^

Am I missing something?

Yes, you have imported everything from net.sf.uadetector package, but UADetectorServiceFactory resides in net.sf.uadetector.service

Add

import net.sf.uadetector.service.UADetectorServiceFactory

or

import net.sf.uadetector.service._

And compilation should be okay

Yes, I got what I am missing, but getUserAgentType is not still working so I used getType() in place of that.

import net.sf.uadetector.service._
import net.sf.uadetector._

def check = Action { implicit request =>
  var parser = UADetectorServiceFactory.getOnlineUpdatingParser()
  println(parser)
  val agent = parser.parse(request.headers.get("User-Agent").getOrElse(""))
  println(agent)
  val which = agent.getType()
  println(which)
  Ok(write(Map("result" -> true)))
}

and needed two library dependencies to run the code above:

• "net.sf.uadetector" % "uadetector-core" % "0.9.16",

• "net.sf.uadetector" % "uadetector-resources" % "2013.04",
