Flink連接Zookeeper消費Kafka數據

廢話不多說，直接上代碼片段，示例代碼（scala版本）：

    val env = StreamExecutionEnvironment.getExecutionEnvironment
    // kafka 配置
    val ZOOKEEPER_HOST = "host:prot"
    val KAFKA_BROKERS = "host:port"
    val TRANSACTION_GROUP = "group_id"
    val TOPIC_NAME = "topic"
    val kafkaProps = new Properties()
    kafkaProps.setProperty("zookeeper.connect", ZOOKEEPER_HOST)
    kafkaProps.setProperty("bootstrap.servers", KAFKA_BROKERS)
    kafkaProps.setProperty("group.id", TRANSACTION_GROUP)
    val streamData: DataStream[String] = env.addSource(new FlinkKafkaConsumer011[String](TOPIC_NAME, new SimpleStringSchema(), kafkaProps))
