Apache kafka 无法建立到节点-1的连接。经纪人可能不在。Windows和WSL

下面是一个超级简单的教程，其中包含了最少的配置编辑。 当我尝试在Java应用程序中创建生产者时，它找不到代理。但是，当我设置控制台生产者时，我可以通过同一个代理进行生产和消费

这是我的设置
服务器程序：

offsets.topic.replication.factor=1
transaction.state.log.replication.factor=1
transaction.state.log.min.isr=1

log.retention.hours=168

log.segment.bytes=1073741824

zookeeper.connect=localhost:2181
zookeeper.connection.timeout.ms=18000

group.initial.rebalance.delay.ms=0

dataDir=/mnt/c/Users/majaxing/Downloads/kafka_2.13-2.6.0/data/zookeeper
clientPort=2181
# disable the per-ip limit on the number of connections since this is a non-production config
maxClientCnxns=0
# Disable the adminserver by default to avoid port conflicts.
# Set the port to something non-conflicting if choosing to enable this
admin.enableServer=false

动物园管理员。权限：

offsets.topic.replication.factor=1
transaction.state.log.replication.factor=1
transaction.state.log.min.isr=1

log.retention.hours=168

log.segment.bytes=1073741824

zookeeper.connect=localhost:2181
zookeeper.connection.timeout.ms=18000

group.initial.rebalance.delay.ms=0

dataDir=/mnt/c/Users/majaxing/Downloads/kafka_2.13-2.6.0/data/zookeeper
clientPort=2181
# disable the per-ip limit on the number of connections since this is a non-production config
maxClientCnxns=0
# Disable the adminserver by default to avoid port conflicts.
# Set the port to something non-conflicting if choosing to enable this
admin.enableServer=false

运行这两个命令可以设置消费者/生产者，他们可以通过kafka发送消息

kafka-console-consumer.sh--引导服务器本地主机：9092--主题优先\u主题--将我的第三个应用程序分组

kafka-console-producer.sh--引导服务器本地主机：9092--主题优先\u主题

以下是我创建简单生产者的java代码：

package com.github.jaxing.kafka.tutorial1;

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.common.serialization.StringSerializer;

import java.util.Properties;

public class ProducerDemo {
    public static void main(String[] args) {
        String bootstrapServers =  "localhost:9092";

        // create Producer properties
        Properties properties = new Properties();
        properties.put(ProducerConfig.BOOTSTRAP_SERVERS_CONFIG, bootstrapServers);
        properties.put(ProducerConfig.KEY_SERIALIZER_CLASS_CONFIG, StringSerializer.class.getName());
        properties.put(ProducerConfig.VALUE_SERIALIZER_CLASS_CONFIG, StringSerializer.class.getName());

        // create the producer

        KafkaProducer<String, String> producer = new KafkaProducer<>(properties);

        // create prducer recoder
        ProducerRecord<String, String> record =
                new ProducerRecord<>("first_topic", "hello world");

        // send data
        producer.send(record);

        producer.flush();
        producer.close();
    }
}

我在windows计算机上，但正在WSL2中运行kafka。我曾尝试使用WindowsJavaVersion15和LinuxJava11来运行上述代码，但得到了相同的输出

有人有什么想法吗

谢谢

因为卡夫卡可以在Windows中运行，所以您应该这样做。或者从WSL2运行Java代码
