代码
public static void ProducerSyncSend() throws Exception{
Properties properties=new Properties();
properties.put(ProducerConfig.BOOTSTRAP_SERVERS_CONFIG,“192.168.59.129:9092”);
properties.put(ProducerConfig.ACKS_CONFIG,“all”);

    properties.put(ProducerConfig.KEY_SERIALIZER_CLASS_CONFIG,"org.apache.kafka.common.serialization.StringSerializer");
    properties.put(ProducerConfig.VALUE_SERIALIZER_CLASS_CONFIG,"org.apache.kafka.common.serialization.StringSerializer");

    Producer<String,String>producer=new KafkaProducer<>(properties);

    for (int i=0;i<10;i++) {
        String key="key-i:"+i;
        ProducerRecord<String, String> producerRecord = new ProducerRecord<>(topicName,"key-:"+key
                +"value-:"+i);
        Future<RecordMetadata>send=producer.send(producerRecord);
        RecordMetadata metadata=send.get();
        System.out.println(key+"\t partition:"+metadata.partition()+"\t offset:"+metadata.offset());
    }
    producer.close();
}

是哪里写错了啊
