如果不可用，如何配置 Kafka 生产者停止重试连接到代理？ 我添加了重试配置，但它不起作用，它仍然无限期地重试...... 如果“经纪人可能不可用”，我想跳过这部分 如何解决？
这是我的 Kafka Producer 配置：
@Bean
fun notificationKafkaProducerFactory(): ProducerFactory<String, Email> {
val config = mutableMapOf<String, Any>()
config[ProducerConfig.BOOTSTRAP_SERVERS_CONFIG] = "localhost:9092"
config[ProducerConfig.MAX_IN_FLIGHT_REQUESTS_PER_CONNECTION] = "3"
config[ProducerConfig.RETRIES_CONFIG] = "3"
config[ProducerConfig.RETRY_BACKOFF_MS_CONFIG] = "500"
config[ProducerConfig.KEY_SERIALIZER_CLASS_CONFIG] = JsonSerializerWithJTM::class.java
config[ProducerConfig.VALUE_SERIALIZER_CLASS_CONFIG] = JsonSerializerWithJTM::class.java
return DefaultKafkaProducerFactory(config)
}
@Bean
fun notificationKafkaTemplate(): KafkaTemplate<String, Email> {
return KafkaTemplate(notificationKafkaProducerFactory())
}
上面是尝试发送消息时的样子：
