kafka准备工作：

开启zookeeper服务和kafka服务

zkServer.sh start

kafka-server-start.sh /opt/soft/kafka211/config/server.properties

创建副本为1，分区为4的topic：mydemo1

kafka-topics.sh --zookeeper 192.168.181.132:2181 --create --topic mydemo1 --replication-factor 1 --partitions 4

JAVA开多线程写入数据：

接口：

package org.example.commons;

import java.util.Map;

public interface Dbinfo {
   
   
    public String getIp();
    public int getPort();
    public String getDbName();
    public Map<String,String>getOther();

}

kafka配置类：

package org.example.commons;

import java.util.Map;

public class KafkaConfiguration implements Dbinfo
{
   
   
    private String ip;
    private int port;
    private String Dbname;

    public void setIp(String ip) {
   
   
        this.ip = ip;
    }

    public void setPort(int port) {
   
   
        this.port = port;
    }

    public String getDbname() {
   
   
        return Dbname;
    }

    public void setDbname(String dbname) {
   
   
        this.Dbname = dbname;
    }

    @Override
    public String getIp() {
   
   
        return this.ip;
    }

    @Override
    public int getPort() {
   
   
        return this.port;
    }

    @Override
    public String getDbName() {
   
   
        return this.Dbname;
    }

    @Override
    public Map<String, String> getOther() {
   
   
        return null;
    }
}

kafkaConnector类：

package org.example.commons;

import org.apache.kafka.clients.admin.AdminClient;
import org.apache.kafka.clients.admin.DescribeTopicsResult;
import org.apache.kafka.clients.admin.KafkaAdminClient;
import org.apache.kafka.clients.admin.TopicDescription;
import org.apache.kafka.clients.producer.ProducerConfig;
import org.apache.kafka.common.KafkaFuture;
import org.apache.kafka.common.serialization.StringSerializer;

import java.io.FileNotFoundException;
import java.io.FileReader;
import java.io.IOException;
import java.io.LineNumberReader;
import java.util.*;
import java.util.concurrent.ExecutionException;

public class KafkaConnector {
   
   
    private Dbinfo info;
    private int totalRow;
    private List<Long> rowSize = new ArrayList<>()
