    • close

      public void close()
      从接口复制的说明: ProducerInterceptor
      Close the interceptor.

    • eligible

      public boolean eligible(Message message)
      从接口复制的说明: ProducerInterceptor
      Check whether the interceptor is eligible for this message.
      指定者:
      eligible 在接口中 ProducerInterceptor
      参数:
      message - message to send
      返回:
      whether the interceptor can be applied to this particular message.

    • beforeSend

      public Message beforeSend(Producer producer, Message message)
      从接口复制的说明: ProducerInterceptor
      This is called from Producer.send(Object) and Producer.sendAsync(Object) methods, before send the message to the brokers. This method is allowed to modify the record, in which case, the new record will be returned.

      Any exception thrown by this method will be caught by the caller and logged, but not propagated further.

      Each interceptor will be passed the message returned by the last successful executed interceptor or the original message if it is the first one. Since interceptors are allowed to modify messages, interceptors may potentially get the message already modified by other interceptors. However, building a pipeline of mutable interceptors that depend on the output of the previous interceptor is discouraged, because of potential side-effects caused by interceptors potentially failing to modify the message and throwing an exception.

      指定者:
      beforeSend 在接口中 ProducerInterceptor
      参数:
      producer - the producer which contains the interceptor.
      message - message to send
      返回:
      the intercepted message

    • onSendAcknowledgement

      public void onSendAcknowledgement(Producer producer, Message message, MessageId msgId, Throwable exception)
      从接口复制的说明: ProducerInterceptor
      This method is called when the message sent to the broker has been acknowledged, or when sending the message fails. This method is generally called just before the user callback is called, and in additional cases when an exception on the producer side.

      Any exception thrown by this method will be ignored by the caller.

      This method will generally execute in the background I/O thread, so the implementation should be reasonably fast. Otherwise, sending of messages from other threads could be delayed.

      指定者:
      onSendAcknowledgement 在接口中 ProducerInterceptor
      参数:
      producer - the producer which contains the interceptor.
      message - the message that application sends
      msgId - the message id that assigned by the broker; null if send failed.
      exception - the exception on sending messages, null indicates send has succeed.

    • onPartitionsChange

      public void onPartitionsChange(String topicName, int partitions)
      从接口复制的说明: ProducerInterceptor
      This method is called when partitions of the topic (partitioned-topic) changes.
      指定者:
      onPartitionsChange 在接口中 ProducerInterceptor
      参数:
      topicName - topic name
      partitions - new updated partitions
