当我试着运行我的 SupplierConsumer 在eclipse中初始化。这是我的密码：

public class SupplierConsumer{

    public static void main(String[] args) throws Exception{

            String topicName = "SupplierTopic";
            String groupName = "SupplierTopicGroup";

            Properties props = new Properties();
            props.put("bootstrap.servers", "localhost:9092,localhost:9093");
            props.put("group.id", groupName);
            props.put("key.deserializer", "org.apache.kafka.common.serialization.StringDeserializer");
            props.put("value.deserializer", "SupplierDeserializer");

            KafkaConsumer<String, Supplier> consumer = new KafkaConsumer<>(props);
            consumer.subscribe(Arrays.asList(topicName));

            while (true){
                    ConsumerRecords<String, Supplier> records = consumer.poll(100);
                    for (ConsumerRecord<String, Supplier> record : records){
                            System.out.println("Supplier id= " + String.valueOf(record.value().getID()) + " Supplier  Name = " + record.value().getName() + " Supplier Start Date = " + record.value().getStartDate().toString());
                    }
            }
    }
}
