##  4：springboot项目发布和消费kafka ##

###  4-1：application.yml ###

server:
      port: 9088
    
    spring:
      kafka:

          value-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;

     */
    @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

            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 {
        
        @Resource
        KafkaProducerService 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
