工作中使用Kafka接收消息代码整理

前段时间工作中使用到Kafka接收消息，简单整理一下：

Properties props = new Properties();
props.put("zookeeper.connect", zkServer);
props.put("group.id",groupId);
//使用zk集群管理
ConsumerConfig conf = new ConsumerConfig(props);
kafka.javaapi.consumer.ConsumerConnector consumer = kafka.consumer.Consumer.createJavaConsumerConnector(conf);
Map<String, Integer> topicCountMap = new HashMap<String, Integer>();
topicCountMap.put(topicId, 1);
Map<String, List<KafkaStream<String, LogInfoBean>>> consumerMap =
consumer.createMessageStreams(topicCountMap,new StringDecoder(new VerifiableProperties()), new DiggerEventDecoder());
List<KafkaStream<String,LogInfoBean>> streams = consumerMap.get(topicId);
KafkaStream<String,LogInfoBean> stream = streams.get(0);
ConsumerIterator<String,LogInfoBean> it = stream.iterator();
//没有消息时会阻塞线程
while (it.hasNext()){
LogInfoBean msgBean = it.next().message();
String logMessage = msgBean.getMsg();
//处理接收到的消息
//...
}
