Is there a way to add a log writer factory into the logger configuration? - zend-framework2

Question

I write logger config and used Zend\Log\LoggerServiceFactory for configure Logger. If I use base writers all work. But I want add to a logger my own writer who created by factory, and this is donn`t work.
Is there a way to use config and base logger factory to add writer from own factory?
Update: here is my code
This is my config where I define factory for Logger, factory for writer and configs for base writers
// config/autoload/global.php
return array(
'service_manager' => array(
'factories' => array(
'Logger' => 'Zend\Log\LoggerServiceFactory',
'Rollbar' => 'Yassa\Rollbar\Log\Writer\Rollbar'
),
),
'log' => array(
'writers' => array(
array(
'name' => 'stream',
'options' => array(
...
),
),
array(
'name' => 'stream',
'options' => array(
...
),
),
array(
'name' => 'Rollbar',
),
),
),
);
Yassa\Rollbar\Log\Writer\Rollbar - it`s a factory from yassa\rollbar module (github)
Without Rollbar writer this config does what I need - create and configure standart writers.
Thus I call logger from aontroller:
$this->getServiceLocator()->get('Logger')->info('test');

Answer 1

I researched the component code and did not find a way to use the factory to create my own writer. Unfortunately currently this is not possible.

Answer 2

I think I found the solution. The solution is not very nice, but nothing better I figured it out.
I wrote a replacement for standard factory (\Zend\Log\LoggerServiceFactory) and transfer logger configuration from the Logger constructor in the my factory. In addition, I added a check for the writer factory.
Here is the resulting class:
<?php
namespace Application\Factory;
use Zend\Log\Exception\InvalidArgumentException;
use Zend\Log\Logger;
use Zend\ServiceManager\FactoryInterface;
use Zend\ServiceManager\ServiceLocatorInterface;
class LoggerServiceFactory implements FactoryInterface
{
public function createService(ServiceLocatorInterface $serviceLocator)
{
// Configure the logger
$config = $serviceLocator->get('Config');
$options = isset($config['log']) ? $config['log'] : array();
$logger = new Logger();
if (is_array($options)) {
if (isset($options['writers']) && is_array($options['writers'])) {
foreach ($options['writers'] as $writer) {
if (!isset($writer['name'])) {
throw new InvalidArgumentException('Options must contain a name for the writer');
}
$priority = (isset($writer['priority'])) ? $writer['priority'] : null;
$writerOptions = (isset($writer['options'])) ? $writer['options'] : null;
if ($serviceLocator->has($writer['name'])) {
$writer = $serviceLocator->get($writer['name']);
$logger->addWriter($writer, $priority, $writerOptions);
} else {
$logger->addWriter($writer['name'], $priority, $writerOptions);
}
}
}
if (isset($options['exceptionhandler']) && $options['exceptionhandler'] === true) {
Logger::registerExceptionHandler($logger);
}
if (isset($options['errorhandler']) && $options['errorhandler'] === true) {
Logger::registerErrorHandler($logger);
}
}
return $logger;
}
}
Can anybody suggest a better solution?
