异常原因

使用kafka事务发送消息的时候没有开启事务

解决方案

加事务前缀，自动给producer开启事务，所有加

# 事务前缀
spring.kafka.producer.transaction-id-prefix=tx_

Must set retries to non-zero when using the idempotent producer.

org.apache.kafka.common.config.ConfigException: Must set retries to non-zero when using the idempotent producer.

解决方案

# 重试次数
spring.kafka.producer.retries=3

Must set acks to all in order to use the idempotent producer. Otherwise we cannot guarantee idempotence.

解决方案

spring.kafka.producer.acks=-1

No transaction is in process; possible solutions: run the template operation within the scope of a template.executeInTransaction() operation, start a transaction with @Transactional before invoking the template method, run in a transaction started by a listener container when consuming a record

解决方案

在方法上加@Transactional注解

	@Transactional
    @GetMapping("/transaction")
    public void sendTransactionMsg(@RequestParam String userId){
        String msg = " transaction "+userId;
        kafkaTemplate.executeInTransaction(new KafkaOperations.OperationsCallback<String, Object, Object>() {

            @Override
            public Object doInOperations(KafkaOperations<String, Object> kafkaOperations) {
                kafkaOperations.send(KafkaTopicConstants.TEST_TRANSACTION , msg);
//                throw new RuntimeException("test transaction");
                return "";
            }
        });
    }

解决方案

ConcurrentKafkaListenerContainerFactory 没有设置replyTemplate

ConcurrentKafkaListenerContainerFactory containerFactory = new ConcurrentKafkaListenerContainerFactory();

containerFactory.setReplyTemplate(kafkaTemplate);
