我正在使用 Spring Boot 2.1.9 和 Spring Kafka 2.2.9。
我的 Spring Boot 应用程序在过去两周内一直处于闲置状态，它正在运行，但仍然没有人访问 API。但是当我今天开始使用时，对于第一个请求，它给了我以下错误。

Caused by: org.apache.kafka.common.errors.InvalidPidMappingException: The producer attempted to use a producer id which is not currently assigned to its transactional id
这个错误是什么原因？任何配置问题！
如果我们不使用，Kafka 服务器会进入空闲状态吗？
出现此问题的原因如下。
transactional.id.expiration.ms。
事务协调器在主动使生产者的事务 ID 过期而不从其接收任何事务状态更新之前等待的最长时间（以毫秒为单位）。
类型：int
默认：604800000
604800000 毫秒是 7 天。所以基本上，如果我们有一个流应用程序 7 天没有流量，它的生产者元数据就会被删除 - 这就是我们所看到的行为：应用程序消费消息，处理它 - 当它尝试提交时事务并更新偏移量，失败。这就是我们加工、粉碎、再加工的原因
生产者尝试使用当前未分配给其事务ID的生产者ID
这可能意味着您有两个独立的制作人使用相同的
transactional.id对于生产者发起的交易，它们在应用程序实例中必须是唯一的。
它记录在 Spring Kafka 文档中，即使很难找到 https://docs.spring.io/spring-kafka/docs/2.8.11/reference/html/#transactions
从版本 2.5.8 开始，您现在可以在生产者工厂上配置 maxAge 属性。当使用可能为代理的 transactional.id.expiration.ms 闲置的事务生产者时，这非常有用。对于当前的 kafka-clients，这可能会导致 ProducerFencedException 且无需重新平衡。通过将 maxAge 设置为小于 transactional.id.expiration.ms，如果生产者超过了最大年龄，工厂将刷新生产者。
因此您应该将 maxAge 设置为小于代理配置值transactional.id.expiration.ms
@Bean
public ProducerFactory<String, YourEvent> inventoryEventProducerFactory() {
DefaultKafkaProducerFactory<String, YourEvent> kafkaProducerFactory =
new DefaultKafkaProducerFactory<>(producerConfigs(), new StringSerializer(), new JsonSerializer<>(
new ObjectMapper().registerModules(new JavaTimeModule())
.disable(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS)));
kafkaProducerFactory.setTransactionIdPrefix(transactionIdPrefix + UUID.randomUUID());
// smaller than transactional.id.expiration.ms. Default: 604800000
kafkaProducerFactory.setMaxAge(Duration.ofMillis(600000000));
return kafkaProducerFactory;
}
