问如何使用带有Spring-kafka kafkaTemplate的sendDefault方法的DefaultPartitioner

EN

/**
 * The default partitioning strategy:
 * <ul>
 * <li>If a partition is specified in the record, use it
 * <li>If no partition is specified but a key is present choose a partition based on a hash of the key
 * <li>If no partition or key is present choose a partition in a round-robin fashion
 */
public class DefaultPartitioner implements Partitioner {

/**
 * Send the data to the default topic with the provided key and no partition.
 * @param key the key.
 * @param data The data.
 * @return a Future for the {@link SendResult}.

ListenableFuture<SendResult<K, V>> sendDefault(K key, V data);

kafkaTemplate.sendDefault(job.getId(),job);
