MessageProcessor 是在ProcessBufferProcessor 使用的，主要进行消息的加工，比如过滤，提取，扩展

ProcessBufferProcessor参考处理

private void handleMessage(@Nonnull Message msg) {

private void handleMessage(@Nonnull Message msg) {
    msg.addStream(defaultStreamProvider.get());
    Messages messages = msg;
    // 消息处理的时候使用MessageProcessor 进行消息的进一步加工
    for (MessageProcessor messageProcessor : orderedMessageProcessors) {
        messages = messageProcessor.process(messages);
    }
 
    for (Message message : messages) {
        message.ensureValidTimestamp();
 
        if (!message.hasField(Message.FIELD_GL2_MESSAGE_ID) || isNullOrEmpty(message.getFieldAs(String.class, Message.FIELD_GL2_MESSAGE_ID))) {
            // Set the message ID once all message processors have finished
            // See documentation of Message.FIELD_GL2_MESSAGE_ID for details
            message.addField(Message.FIELD_GL2_MESSAGE_ID, ulid.nextULID());
        }
 
        // The processing time should only be set once all message processors have finished
        message.setProcessingTime(Tools.nowUTC());
        processingStatusRecorder.updatePostProcessingReceiveTime(message.getReceiveTime());
 
        if(failureSubmissionService.submitProcessingErrors(message)) {
            outputBuffer.insertBlocking(message);
        }
    }
}
