我试着从代码中将分区数设置为2，我有单节点设置（1个zookeeper，1个afka）。当我看到kafka只使用一个分区来存储数据时，我是否需要对设置进行任何修改以拥有多个分区？

private void setupZookeeper(String[] topicList){

    ZkClient zkClient = null;
    ZkUtils zkUtils = null;
    try {
        String[] zookeeperHosts = {"localhost:2181"}; // If multiple zookeeper then -> String zookeeperHosts = "192.168.20.1:2181,192.168.20.2:2181";
        int sessionTimeOutInMs = 15 * 1000; // 15 secs
        int connectionTimeOutInMs = 10 * 1000; // 10 secs
        //String topicName = "testTopic";
        int noOfPartitions = 2;
        int noOfReplication = 1;

        for(String zookeeper:zookeeperHosts){

            zkClient = new ZkClient(zookeeper, sessionTimeOutInMs, connectionTimeOutInMs, ZKStringSerializer$.MODULE$);
            zkUtils = new ZkUtils(zkClient, new ZkConnection(zookeeper), false);
            for(String topicName: topicList){
                System.out.println("Setting no of partitions ="+noOfPartitions + "for topic" + topicName);
                AdminUtils.createTopic(zkUtils, topicName, noOfPartitions, noOfReplication, 
                         producerConfig(),RackAwareMode.Disabled$.MODULE$);
            }
        }

    } catch (Exception ex) {
        ex.printStackTrace();
    } finally {
        if (zkClient != null) {
            zkClient.close();
        }
    }

我的producerconfig如下所示：

private Properties producerConfig() {
   Properties props = new Properties();
  props.put("bootstrap.servers", "localhost:9092");

  props.put("acks", "all");
  //props.put("retries", 0);
  props.put("key.serializer", "org.apache.kafka.common.serialization.StringSerializer");
  props.put("value.serializer", "org.apache.kafka.common.serialization.StringSerializer");

return props;
}
