2.KafkaTopicBean

public class KafkaTopicBean {

    private String topicName;       // topic 名称
    private Integer partition;      // partition 分区数量
    private Integer replication;    // replication 副本数量
    private String descrbe;  

    public String getTopicName() {
        return topicName;
    }  

    public void setTopicName(String topicName) {
        this.topicName = topicName;
    }  

    public Integer getPartition() {
        return partition;
    }  

    public void setPartition(Integer partition) {
        this.partition = partition;
    }  

    public Integer getReplication() {
        return replication;
    }  

    public void setReplication(Integer replication) {
        this.replication = replication;
    }  

    public String getDescrbe() {
        return descrbe;
    }  

    public void setDescrbe(String descrbe) {
        this.descrbe = descrbe;
    }  

    @Override
    public String toString() {
        return "KafkaTopicBean [topicName=" + topicName + ", partition=" + partition
                + ", replication=" + replication + ", descrbe=" + descrbe +"]";
    }  

}

3.KafkaUtil

import java.util.Properties;
import org.apache.kafka.common.security.JaasUtils;
import kafka.admin.AdminUtils;
import kafka.admin.RackAwareMode;
import kafka.utils.ZkUtils;

public class KafkaUtil {

     public static void createKafaTopic(String ZkStr,KafkaTopicBean topic) {
         ZkUtils zkUtils = ZkUtils.
                 apply(ZkStr, 30000, 30000,JaasUtils.isZkSecurityEnabled()); 

        AdminUtils.createTopic(zkUtils, topic.getTopicName(),  topic.getPartition(),
                topic.getReplication(),  new Properties(), new RackAwareMode.Enforced$());
        zkUtils.close();
    }

     public static void deleteKafaTopic(String ZkStr,KafkaTopicBean topic) {
         ZkUtils zkUtils = ZkUtils.
                 apply(ZkStr, 30000, 30000,JaasUtils.isZkSecurityEnabled()); 

        AdminUtils.deleteTopic(zkUtils, topic.getTopicName());
        zkUtils.close();
    }

}

4.调用方式

    public static void main(String[] args) {

        //zookeeper地址：端口号
        String ZkStr = "912.168.0.1:2181";    

        //topic对象
        KafkaTopicBean topic = new KafkaTopicBean();
        topic.setTopicName("testTopic");  //topic名称
        topic.setPartition(1);            //分区数量设置为1
        topic.setReplication(1);        　//副本数量设置为1

        //创建topic
        KafkaUtil.createKafaTopic(ZkStr,topic);
        //删除topic
        KafkaUtil.deleteKafaTopic(ZkStr,topic);

    }
