Kafka学习笔记 --- Scala实现Events, Controls Producer

ProducerEvent:

package zetyunimport java.util.Propertiesimport org.apache.kafka.clients.producer.{KafkaProducer, ProducerRecord}/**  * Created by ryan on 17-7-18.  */object ProducerEvent {  def main(args: Array[String]): Unit ={    val topic = "events"    val props = new Properties()    props.put("bootstrap.servers", "192.168.1.81:6667")    props.put("key.serializer", "org.apache.kafka.common.serialization.StringSerializer")    props.put("value.serializer", "org.apache.kafka.common.serialization.StringSerializer")    val producer = new KafkaProducer[String, String](props)    val message: List[String] = List("{\"customerId\":\"9f20f8a4-d8c8-4a74-ac90-3452b97c2e34\",\"payload\":\"{\\\"store\\\": {\\\"book\\\": [{\\\"category\\\": \\\"reference\\\",\\\"author\\\": \\\"Nigel Rees\\\",\\\"title\\\": \\\"Sayings of the Century\\\",\\\"price\\\": 8.95},{\\\"category\\\": \\\"fiction\\\",\\\"author\\\": \\\"Evelyn Waugh\\\",\\\"title\\\": \\\"Sword of Honour\\\",\\\"price\\\": 12.99},{\\\"category\\\": \\\"fiction\\\",\\\"author\\\": \\\"Herman Melville\\\",\\\"title\\\": \\\"Moby Dick\\\",\\\"isbn\\\": \\\"0-553-21311-3\\\",\\\"price\\\": 8.99},{\\\"category\\\": \\\"fiction\\\",\\\"author\\\": \\\"J.

ProducerControl:

package zetyunimport java.util.Propertiesimport org.apache.kafka.clients.producer.{KafkaProducer, ProducerRecord}/**  * Created by ryan on 17-7-18.  */object ProducerControl {  def main(args: Array[String]): Unit ={    val topic = "controls"    val props = new Properties()    props.put("bootstrap.servers", "192.168.1.81:6667")    props.put("key.serializer", "org.apache.kafka.common.serialization.StringSerializer")    props.put("value.serializer", "org.apache.kafka.common.serialization.StringSerializer")    val producer = new KafkaProducer[String, String](props)    val message: List[String] = List("{\"customerId\":\"deadbeef-dead-beef-dead-beefdeadbeef\",\"alertId\":\"f4b9d5a5-b5d3-41e1-ae8c-2e5d357fb83e\",\"alertName\":\"Testing Alert\",\"alertDescription\":\"This is a test alert.\",\"threshold\":2,\"jsonPath\":\"$.store.book[0].author\"}", "{\"customerId\":\"deadbeef-dead-beef-dead-beefdeadbeef\",\"alertId\":\"f4b9d5a5-b5d3-41e1-ae8c-2e5d357fb83e\",\"alertName\":\"Testing Alert\",\"alertDescription\":\"This is a test alert.\",\"threshold\":2,\"jsonPath\":\"$.store.book[0].author\"}")    for(i <- 0 to message.length - 1){      val record = new ProducerRecord(topic, Integer.toString(i + 1), message(i))      producer.send(record)      println(message(i))    }    producer.close()  }}
