У меня есть приложение Java polyglot, которое в основном содержит код Java и также использует несколько библиотек Scala.
Код ниже Scala компилируется нормально.
import com.twitter.finagle.Http.Client
import com.twitter.finagle.Http
import com.twitter.finagle.param.Logger
object Main extends App {
private val loggerFinagle = java.util.logging.Logger.getLogger("FinagleLogger")
val client: Client = Http.client
.configured(Logger(loggerFinagle))
}
Я пишу тот же код вJava, как показано ниже
import com.twitter.finagle.Http;
import com.twitter.finagle.param.Logger;
public class JavaMain {
public static void main(String[] args) {
java.util.logging.Logger loggerFinagle = java.util.logging.Logger.getLogger("FinagleLogger");
Http.client()
.configured(new Logger(loggerFinagle));
}
}
Когда я компилирую код, я получаю ошибку ниже -

Похоже, я должен передать кортеж, но я не знаю, как.
