示例1: KafkaConsumer
//设置package包名称以及导入依赖的类
package services
import java.util.Properties
import akka.actor.{Props, Actor}
import kafka.consumer.{KafkaStream, Consumer, ConsumerConfig}
import play.Logger
object KafkaConsumer {
def props(topic: String): Props = Props(new KafkaConsumer(topic))
}
class KafkaConsumer(topic: String) extends Actor {
val props = new Properties()
props.put("auto.commit", "true")
//props.put("zookeeper.connect", "localhost:2181")
props.put("zookeeper.connect", "zookeeper1:2181")
def receive = {
case group: String => {
props.put("group.id", group)
val connector = Consumer.create(new ConsumerConfig(props))
val stream: KafkaStream[Array[Byte], Array[Byte]] = connector.createMessageStreams(Map(topic -> 1)).get(topic).get(0)
try {
for (message <- stream) {
try {
Logger.debug(new String(message.message()))
} catch {
case e: Throwable => Logger.error("error processing message, skipping and resume consumption: " + e)
}
}
}
}
}
} 示例2: ConsumerRunner
//设置package包名称以及导入依赖的类
package com.rockiey.kafka

val threadNumber: Int) extends Runnable {
override def run(): Unit = {
val it = stream.iterator()
