resources里面添加log4j.properties文件，可以更改打印日志的级别为error

Flink生产者

public class FlinkafkaProducer1{public static void main(String[] args){//获取环境StreamExecutionEnvironment env = StreamExecutionEnvironment.getExecutionEnvironment();env.setParallelism(3);//准备数据源ArrayList<String> wordList = new ArrayList<>();wordList.add("hello");wordList.add("atguigu");DataStreamSource<String> stream = env.fromCollection();//创建一个kafka生产者Properties properteis = new Properties();properties.put(ProducerConfig.BOOTSTRAP_SERVERS_CONFIG,"hadoop102:9092,hadoop103:9092");FlinkKafkaProducer<String> kafkaProducer = new FlinkKafkaProducer<>("first",new SimpleStringSchema(),properties);//添加数据源Kafka生产者stream.addSink(kafkaProducer);//执行env.execute();}
}

Flink消费者

public class FlinkafkaConsumer1{public static void main(String[] args){//获取环境StreamExecutionEnvironment env = StreamExecutionEnvironment.getExecutionEnvironment();env.setParallelism(3);//创建一个消费者Properties properties = new Properties();properties.put(ConsumerConfig.BOOTSTRAP_SERVERS_CONFIG,"hadoop102:9092,hadoop103:9092");properties.put(ConsumerConfig.GROUP_ID_CONFIG,"test");FlinkKafkaConsumer<String> kafkaConsumer = new FlinkKafkaConsumer<>("first",new SimpleSStringSchema(),properties);//关联消费者和flink流env.addSource(kafkaConsumer).print();//执行env.execute();}
