原因分析

这种情况，肯定要先看网络问题嘛

• 首先查看本机防火墙的配置

结果都是关闭的 （建议开放特定端口）

代码语言：javascript复制

[root@localhost bin]# systemctl status firewalld.service
● firewalld.service - firewalld - dynamic firewall daemon
   Loaded: loaded (/usr/lib/systemd/system/firewalld.service; disabled; vendor preset: enabled)
   Active: inactive (dead)
     Docs: man:firewalld(1)
[root@localhost bin]#

不关闭防火墙，但是建议本机防火墙开放特定端口，可以使用如下命令 （使用root账户）

代码语言：javascript复制

firewall-cmd --zone=public --add-port=2181/tcp --permanent
firewall-cmd --zone=public --add-port=9092/tcp --permanent
firewall-cmd --reload
firewall-cmd --list-ports

比如

代码语言：javascript复制

[root@localhost bin]# systemctl status  firewalld
● firewalld.service - firewalld - dynamic firewall daemon
   Loaded: loaded (/usr/lib/systemd/system/firewalld.service; disabled; vendor preset: enabled)

• 接着看看kafka中间件的配置， 问题就在这里

我并没有大改配置，具体的配置可参考 Kafak - 单机/集群快速安装指北(3.x版本)

如下的配置并没有修改

要解决这个问题，修改如上配置即可

Code

代码语言：javascript复制

package com.artisan.pc;

import org.apache.kafka.clients.producer.KafkaProducer;
import org.apache.kafka.clients.producer.ProducerConfig;
import org.apache.kafka.clients.producer.ProducerRecord;
import org.apache.kafka.clients.producer.RecordMetadata;
import org.apache.kafka.common.serialization.StringSerializer;

import java.util.Properties;
import java.util.concurrent.ExecutionException;

/**
 * @author 小工匠
 * @version 1.0
 * @mark: show me the code , change the world
 */
public class CustomProducer {

    public static void main(String[] args) throws ExecutionException, InterruptedException {

        // 1. 创建kafka生产者的配置对象
        Properties properties = new Properties();

        // 2. 给kafka配置对象添加配置信息
        properties.put(ProducerConfig.BOOTSTRAP_SERVERS_CONFIG, "192.168.126.170:9092");

        // key,value序列化
        properties.put(ProducerConfig.KEY_SERIALIZER_CLASS_CONFIG, StringSerializer.class.getName());
        properties.put(ProducerConfig.VALUE_SERIALIZER_CLASS_CONFIG, StringSerializer.class.getName());

        // 3. 创建kafka生产者对象
        KafkaProducer<String, String> kafkaProducer = new KafkaProducer<String, String>(properties);

        // 4. 调用send方法,发送消息
        for (int i = 0; i < 10; i  ) {
        	// 同步阻塞 
            RecordMetadata art = kafkaProducer.send(new ProducerRecord<>("art", "kafka-msg-"   i)).get();
            System.out.println(art.topic());
            System.out.println("over - "  i);
        }

        // 5. 关闭资源
        kafkaProducer.close();

    }

}

可以看消费者的控制台程序，输出正常
