kafka伪集群部署，使用zookeeper模式

1:拉去管理kafka界面UI镜像

docker pull provectuslabs/kafka-ui

2:拉去管理kafka镜像

docker pull bitnami/kafka

3:docker-compose.yml

version: '3.8'

4：springboot项目发布和消费kafka

4-1：application.yml

server:port: 9088spring:kafka:consumer:bootstrap-servers: localhost:19092,localhost:29093,localhost:39092group-id: test-groupauto-offset-reset: earliestproducer:bootstrap-servers: localhost:19092,localhost:29092,localhost:39092key-serializer: org.apache.kafka.common.serialization.StringSerializervalue-serializer: org.apache.kafka.common.serialization.StringSerializer

4-2：消费者

package com.example.kafkademo.config;import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.kafka.annotation.KafkaListener;
import org.springframework.stereotype.Service;/*** @Author xu* @create 2023/9/27 19*/
@Service
public class KafkaConsumerService {private static final Logger LOGGER = LoggerFactory.getLogger(KafkaConsumerService.class);@KafkaListener(topics = "topic")public void receiveMessage(String message) {LOGGER.info("received message='{}'", message);}
}

4-3：生产者

package com.example.kafkademo.config;import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.kafka.core.KafkaTemplate;
import org.springframework.stereotype.Service;/*** @Author xu* @create 2023/9/27 19*/
@Service
public class KafkaProducerService {private static final Logger LOGGER = LoggerFactory.getLogger(KafkaProducerService.class);@Autowiredprivate KafkaTemplate<String, String> kafkaTemplate;public void sendMessage(String topic, String message) {LOGGER.info("sending message='{}' to topic='{}'", message, topic);kafkaTemplate.send(topic, message);}
}

4-4：controller

package com.example.kafkademo.controller;import com.example.kafkademo.config.KafkaProducerService;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RestController;import javax.annotation.Resource;/*** @Author xu* @create 2023/9/27 19*/
@RestController
public class KafkaController {@ResourceKafkaProducerService kafkaProducerService;@PostMapping("/publish")public String publish(String topic,String content){kafkaProducerService.sendMessage("topic",content);System.out.println("content");return content;}
}

5：命令行方式启动kafka

docker run -d --name kafka2 -p 19092:19092 -e KAFKA_CFG_ZOOKEEPER_CONNECT=192.168.11.50:2181 -e KAFKA_CFG_ADVERTISED_LISTENERS=PLAINTEXT://192.168.11.50:19092  -e KAFKA_CFG_LISTENERS=PLAINTEXT://:19092 -e ALLOW_PLAINTEXT_LISTENER=yes -e KAFKA_BROKER_ID=2 bitnami/kafka

6：命令行方式启动kafka-ui

docker run -d --name kafka-ui -p 8080:8080 -e KAFKA_CLUSTERS_0_BOOTSTRAPSERVERS=192.168.11.50:19092 provectuslabs/kafka-ui

7：命令行方式启动zookeeper

docker run -d --name zookeeper -p 2181:2181 -e ALLOW_ANONYMOUS_LOGIN=yes bitnami/zookeeper
