我读了很多关于配置的主题，但还是不明白。
当我这样做时：

../kafka_2.11-1.1.0/bin/kafka-topics.sh --zookeeper localhost:2181 --alter --topic my_topic --config max.message.bytes=10000000

这很有帮助
但在我的申请表里，a什么都试过了

def producerSettings(system: ActorSystem): ProducerSettings[String, KafkaMessage] =
    ProducerSettings(system, new StringSerializer, new GenericSerde[KafkaMessage].serializer())
      .withBootstrapServers("localhost:9092")
      .withProperty("auto.create.topics.enable", "true")
      .withProperty("replica.fetch.max.bytes", maxSize)
      .withProperty("message.max.bytes", maxSize)

val producer: KafkaProducer[String, KafkaMessage] = configuration.producerSettings(context.system)
    .withBootstrapServers("localhost:" + config.getInt("kafka.port"))
    .withProperty("message.max.bytes", maxSize)
    .withProperty("max.request.size", maxSize)
    .createKafkaProducer()

当我开始清理Kafka-我看到日志

INFO Created log for partition my_topic-0 in /tmp/kafka-logs with properties {compression.type -> producer, message.format.version ->
1.1-IV0, file.delete.delay.ms -> 60000, max.message.bytes -> 1000012, min.compaction.lag.ms -> 0, message.timestamp.type -> CreateTime, min.insync.replicas -> 1, segment.jitter.ms -> 0, preallocate -> false, min.cleanable.dirty.ratio -> 0.5, index.interval.bytes -> 4096, unclean.leader.election.enable -> false, retention.bytes -> -1, delete.retention.ms -> 86400000, cleanup.policy -> [delete], flush.ms

a你看 max.message.bytes ->1000012仍为默认值，我必须再次记录大消息异常
我做错了什么？我想通过我的应用程序进行配置-而不是控制台命令。有可能吗？
