1、消费异常处理

1.1、application.yml配置

server:
  port: 8120

# v1
spring:
  Kafka:
    bootstrap-servers: 192.168.74.148:9095,192.168.74.148:9096,192.168.74.148:9097
    consumer:
      # read-committed读事务已提交的消息 解决脏读问题
      isolation-level: read-committed # 消费者的事务隔离级别：read-uncommitted会导致脏读，可以读取生产者事务还未提交的消息
      # 消费者是否自动ack ：true自动ack 消费者获取到消息后kafka提交消费者偏移量
      # 调用ack方法时才会提交ack给kafka
#      enable-auto-commit: false
      # 消费者提交ack时多长时间批量提交一次
      auto-commit-interval: 1000
      # 消费者第一次消费主题消息时从哪个位置开始
      # earliest:从最早的消息开始消费
      # latest:第一次从LEO位置开始消费
      # none:如果主题分区没有偏移量，则抛出异常
      auto-offset-reset: earliest  #指定Offset消费:earliest | latest | none
      key-deserializer: org.apache.kafka.common.serialization.StringDeserializer
      value-deserializer: org.apache.kafka.common.serialization.StringDeserializer
    listener:
      # 手动ack：manual手动ack时 如果有异常会尝试一直消费
#      ack-mode: manual
      # 手动ack：消费有异常时停止
      ack-mode: manual_immediate

1.2、注册异常处理器

package com.atguigu.spring.kafka.consumer.config;
import org.apache.kafka.clients.admin.NewTopic;
import org.apache.kafka.clients.consumer.Consumer;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.kafka.config.TopicBuilder;
import org.springframework.kafka.listener.ConsumerAwareListenerErrorHandler;
import org.springframework.kafka.listener.ListenerExecutionFailedException;
import org.springframework.messaging.Message;
@Configuration
public class MyKafkaConfig {
@Bean
public NewTopic springTestPartitionTopic() {
return TopicBuilder.name("my_topic1") //主题名称
.partitions(3) //分区数量
.replicas(3) //副本数量
.build();
}
//方法名就是注入到容器中对象的名称
@Bean
public ConsumerAwareListenerErrorHandler myErrorHandler() {
//创建异常处理器：消费者异常时 且注册使用当前异常处理器 会生效
return new ConsumerAwareListenerErrorHandler() {
@Override
public Object handleError(Message<?> message, ListenerExecutionFailedException e, Consumer<?, ?> consumer) {
System.out.println("出现异常，消息内容：value = " + message.getPayload());
System.out.println("header = "+message.getHeaders());
System.out.println("异常信息：" + e.getMessage());
System.out.println("=================");
return null;
}
};
}
}

1.3、消费者使用异常处理器

package com.atguigu.spring.kafka.consumer.listener;
import org.apache.kafka.clients.consumer.ConsumerRecord;
import org.springframework.kafka.annotation.KafkaListener;
import org.springframework.kafka.annotation.TopicPartition;
import org.springframework.kafka.support.Acknowledgment;
import org.springframework.stereotype.Component;
@Component
public class MyKafkaListenerAck {
/**
* 自动ack可能会导致漏消息
*      spring-kafka：
*                     自动ack 如果有异常，会死循环获取消息重新消费
*                        不能继续向后消费消息，会导致消息积压
*
*                    手动ack 配置了手动ack，且ack-mode为manual_immediate时，
*                        如果消息消费失败，会继续向后消费
* @param record
*/
@KafkaListener(
topicPartitions = {
@TopicPartition(topic = "my_topic1",partitions = {"0"})}
, groupId = "my_group1",errorHandler = "myErrorHandler")
public void onMessage1(ConsumerRecord<String, String> record, Acknowledgment acknowledgment) {
System.out.println("my_group1消费者获取分区0的消息：topic = "+ record.topic()
+"，partition:"+record.partition()
+"，offset = "+record.offset()
+"，key = "+record.key()
+"，value = "+record.value());
int i = 1/0;
// 手动ack：手动确认消息已经消费 broker 会提交消费者偏移量
acknowledgment.acknowledge();
}
}

1.4、创建生产者发送消息

package com.atguigu.spring.kafka.consumer;
import jakarta.annotation.Resource;
import org.junit.jupiter.api.Test;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.kafka.core.KafkaTemplate;
@SpringBootTest
class SpringKafkaConsumerApplicationTests {
@Resource
KafkaTemplate kafkaTemplate;
@Test
void contextLoads() {
for (int i = 0; i < 10; i++) {
kafkaTemplate.send("my_topic1",i%3,"", "指定ack-mode: manual_immediate消费"+i);
}
}
}

1.5、创建SpringBoot启动类

package com.atguigu.spring.kafka.consumer;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
// Generated by http://start.springboot.io
// 优质的 spring/boot/data/security/cloud 框架中文文档尽在 => http://springdoc.cn
@SpringBootApplication
public class SpringKafkaConsumerApplication {
public static void main(String[] args) {
SpringApplication.run(SpringKafkaConsumerApplication.class, args);
}
}

1.6、屏蔽 kafka debug 日志 logback.xml

<configuration>　　　　　　

<logger name="org.apache.kafka.clients" level="debug" />
</configuration>

1.7、引入spring-kafka依赖

1.8、消费者控制台：

此时如果不关闭SpringKafkaConsumerApplication，生产者继续发送消息，消费者只会往后消费，不会从头再次消费
