之前用过老的api,但是最近在写消费的时候，发现之前老的api很多方法都out了，又去官网看了下最新的0.10.x的api.
1，producer
<dependency> <groupId>org.apache.kafka</groupId> <artifactId>kafka-clients</artifactId> <version>0.10.1.0</version> </dependency>
public static void main(String[] args) {
Properties props = new Properties();
props.put("bootstrap.servers", "192.168.1.31:9092");
props.put("acks", "all");
props.put("retries", 0);
props.put("batch.size", 16384);
props.put("linger.ms", 1);
props.put("buffer.memory", 33554432);
props.put("key.serializer", "org.apache.kafka.common.serialization.StringSerializer");
props.put("value.serializer", "org.apache.kafka.common.serialization.StringSerializer");
Producer<String, String> producer = new KafkaProducer<>(props);
for(int i = 0; i < 100; i++)
producer.send(new ProducerRecord<String, String>("defaultTopic", Integer.toString(i), String.valueOf(i)));
producer.close();
}
2,Comsumer
<dependency> <groupId>org.apache.kafka</groupId> <artifactId>kafka-clients</artifactId> <version>0.10.1.0</version> </dependency>
public static void main(String[] args) {
Properties props = new Properties();
props.put("bootstrap.servers", "192.168.1.31:9092");
props.put("group.id", "test");
props.put("enable.auto.commit", "true");
props.put("auto.commit.interval.ms", "1000");
props.put("key.deserializer", "org.apache.kafka.common.serialization.StringDeserializer");
props.put("value.deserializer", "org.apache.kafka.common.serialization.StringDeserializer");
KafkaConsumer<String, String> consumer = new KafkaConsumer<>(props);
consumer.subscribe(Arrays.asList("defaultTopic"));
while (true) {
ConsumerRecords<String, String> records = consumer.poll(10);
for (ConsumerRecord<String, String> record : records)
System.out.printf("offset = %d, key = %s, value = %s%n", record.offset(), record.key(), record.value());
}
}
