## springboot整合kafka-笔记 ##

### 配置pom.xml ###

这里我的springboot版本是2.3.8.RELEASE，使用的kafka-mq的版本是2.12

<dependencyManagement>
            <dependencies>
                <dependency>

                    <scope>import</scope>

                    <groupId>org.apache.kafka</groupId>
                    <artifactId>kafka-clients</artifactId>
                    <version>2.3.1</version>
                </dependency>
            </dependencies>
        </dependencyManagement>
    	
    	<dependencies>
    
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-web</artifactId>
            </dependency>
    		 <dependency>
                <groupId>org.springframework.kafka</groupId>
                <artifactId>spring-kafka</artifactId>

                <version>2.3.1</version>
            </dependency>
       </dependencies>

### 配置application.yml ###

spring:
      kafka:
        bootstrap-servers: 10.1.5.212:9092

### 配置EnableKafka注解 ###

@EnableKafka
    @EnableScheduling
    @SpringBootApplication
    public class DemoApplication {
        
        public static void main(String[] args) {
        
            SpringApplication.run(DemoApplication.class,args);
        }
    }

### 定义kafka消息生产者 ###

package cn.test.kafka;
    
    import lombok.extern.slf4j.Slf4j;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.kafka.core.KafkaTemplate;
    import org.springframework.stereotype.Service;
    @Slf4j
    @Service
    public class KafkaProducerService {
        
    
        @Autowired
        private  KafkaTemplate<String, String> kafkaTemplate;
        private  String topic= "my816topic";
    
        public void sendMessage(String message){
        
            log.info("向kafka发送消息:{}",message);
            kafkaTemplate.send(topic,message);
        }
    }

### 定义kafka消息消费者 ###

package cn.test.kafka;
    
    import lombok.extern.slf4j.Slf4j;
    import org.springframework.kafka.annotation.KafkaListener;
    import org.springframework.stereotype.Service;
    
    @Slf4j
    @Service
    public class KafkaConsumerService {
        
    
        @KafkaListener(topics = "my816topic",groupId = "mygroup")
        public void listen(String message){
        
          log.info("rec msg:{}",message);
        }
    }

### 测试发送kafka消息 ###

@Component
    @Slf4j
    public class TestJob {
        
     @Autowired
        private ObjectMapper objectMapper;
    
        @Autowired
        private KafkaProducerService kafkaProducerService;
    
        @Scheduled(cron = "0/13 * * * * ?")
        public void hwreg() {
        
            String s = null;
            try {
        
                s = objectMapper.writeValueAsString(new CityInfo("hefei"+System.currentTimeMillis(), 117.17, 31.52));
            } catch (JsonProcessingException e) {
        
                e.printStackTrace();
            }
    
            //测试发送字符串消息
            kafkaProducerService.sendMessage(s);
    
    }
