我正在尝试配置我的kafkaconsumer，以便通过“kafkatopic”从kafkaproducer读取数据。
我的scala代码是：

package com.sundogsoftware.sparkstreaming

    import java.util
    import java.util.Properties
    import org.apache.kafka.clients.consumer.KafkaConsumer
    import scala.collection.JavaConverters._
    import org.apache.kafka.clients.consumer.{ ConsumerRecords, KafkaConsumer }
    import org.apache.kafka.clients.producer.{ KafkaProducer, Producer, ProducerConfig, ProducerRecord }
    import java.util.Arrays;

object ConsumerExample extends App {
  val props = new Properties()
  props.put("bootstrap.servers", "localhost:9092");
  props.put("group.id", "test-group");
  props.put("enable.auto.commit", "true");
  props.put("auto.commit.interval.ms", "1000");
  props.put("session.timeout.ms", "30000");
  props.put("key.deserializer", "org.apache.kafka.common.serialization.StringDeserializer");
  props.put("value.deserializer", "org.apache.kafka.common.serialization.StringDeserializer");
  props.put("partition.assignment.strategy", "range");

  val consumer = new KafkaConsumer[String, String](props)

  consumer.subscribe(Arrays.asList("kafkatopic"))

  while (true) {
    val records = consumer.poll(100)
    println(consumer)
    println(records)
    for (record <- records.asScala) {
      println(record)
    }
  }
}

错误出现在consumer.subscribe（arrays.aslist（“kafkatopic”））：
重载方法值subscribe with alternatives:（x$1:org.apache.kafka.common.topicpartition*）unit（x$1:string*）unit不能应用于（java.util.list[string]）
