本文介绍了如何使用Kafka的管理API进行操作，包括添加POM依赖，编写Java代码来获取Topic列表、创建、修改和删除Topic，以及处理消费组操作。特别提醒，在开发中要注意避免jar包版本错误的问题，作者分享了个人经验并欢迎读者交流讨论。

实现kafka的管理端操作API步骤如下：

1.添加pom依赖：

<dependency>
            <groupId>org.springframework.kafka</groupId>
            <artifactId>spring-kafka</artifactId>
            <version>1.1.0</version>
        </dependency>
        <dependency>
            <groupId>org.apache.kafka</groupId>
            <artifactId>kafka_2.12</artifactId>
            <version>1.1.0</version>
        </dependency>

2.编写java操作语句：

import com.com.wj.kafkaAPI.conf.KafkaConsumerConfig;
import kafka.admin.AdminClient;
import kafka.admin.AdminUtils;
import kafka.admin.RackAwareMode;
import kafka.cluster.Broker;
import kafka.cluster.Cluster;
import kafka.consumer.ConsumerConfig;
import kafka.consumer.KafkaStream;
import kafka.coordinator.group.GroupOverview;
import kafka.javaapi.consumer.ConsumerConnector;
import kafka.javaapi.consumer.ZookeeperConsumerConnector;
import kafka.server.ConfigType;
import kafka.utils.ZkUtils;
import org.apache.kafka.common.TopicPartition;
import org.apache.kafka.common.security.JaasUtils;
import org.apache.zookeeper.KeeperException;
import org.apache.zookeeper.ZooKeeper;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.autoconfigure.condition.ConditionalOnExpression;
import org.springframework.stereotype.Component;
import scala.collection.JavaConversions;
import scala.collection.Map;
import scala.collection.Set;
import java.io.IOException;
import java.util.*;

public class ConsoleApi {
   
   
    @Autowired
    private  KafkaConsumerConfig consumerConfig;
    private  ZkUtils zkUtils = null;
    private ZooKeeper zooKeeper = null;

    /**
     * -获取集群信息（与getAllBrokersInCluster（）只是返回类型不一致）
     */
    public  Cluster getCluster(){
        zkUtils = ZkUtils.apply(consumerConfig.getZookeeperConn(), 30000, 30000, JaasUtils.isZkSecurityEnabled());
        return zkUtils.getCluster();
    }
      public  void getLeaderAndIsrForPartition(String topicName,int patition){
          zkUtils = ZkUtils.apply(consumerConfig.getZookeeperConn(), 30000, 30000, JaasUtils.isZkSecurityEnabled());
          System.out.println("打印："+zkUtils.getLeaderAndIsrForPartition(topicName,patition));
    }

    public boolean createConsumer(String groupId,String topic) {
        try {
            Properties properties = new Properties();
            properties.put("zookeeper.connect", consumerConfig.getZookeeperConn());//声明zk
            properties.put("group.id", groupId);
            ConsumerConnector consumer = new
