2.KafkaTopicBean

public class KafkaTopicBean {        private String topicName;       // topic 名稱    private Integer partition;      // partition 分區數量    private Integer replication;    // replication 副本數量    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.調用方式

    public static void main(String[] args) {                //zookeeper地址：連接埠        String ZkStr = "192.168.1.101:2181";                    //topic對象        KafkaTopicBean topic = new KafkaTopicBean();            topic.setTopicName("testTopic");                            topic.setPartition(1);        topic.setReplication(1);                //建立topic        KafkaUtil.createKafaTopic(ZkStr,topic);        //刪除topic        KafkaUtil.deleteKafaTopic(ZkStr,topic);        
　　}
