我正在使用Apache Kafka。我創建了一個戰爭文件,其中生產者用Java編碼,用戶用Scala編碼。生產者從HTML頁面獲取數據。我可以看到生產者發佈的大部分數據都在消費者身上找到,但有些數據丟失了。Apache Kafka Java生產者Scala消費者缺少流
這裏是我的製片代碼
文件1
package com.cts.rest;
import java.util.Properties;
import kafka.producer.ProducerConfig;
public class Configuration {
static ProducerConfig setKafkaProducerParameter() {
Properties properties = new Properties();
properties.put("zk.connect", "localhost:2181");
properties.put("metadata.broker.list", "localhost:9092");
properties.put("serializer.class", "kafka.serializer.StringEncoder");
properties.put("acks", 0);
ProducerConfig producerConfig = new ProducerConfig(properties);
return producerConfig;
}
}
文件2
package com.cts.rest;
import kafka.javaapi.producer.Producer;
import kafka.producer.KeyedMessage;
import kafka.producer.ProducerConfig;
public class RTTSKProducer {
static void sendDataToProducer(String line){
ProducerConfig producerConfig = configuration.setKafkaProducerParameter();
Producer<String, String> producer = new Producer<String, String>(producerConfig);
String topic = "jsondata";
KeyedMessage<String, String> msg = new KeyedMessage<String, String>(topic, line);
System.out.print(msg);
producer.send(msg);
producer.close();
}
}
現在我檢查消費者的全光照的消息g以下命令。
bin\windows\kafka-console-consumer.bat --zookeeper localhost:2181 --topic jsondata --from-beginning
我是否缺少任何生產者配置?
