How to Set Up CronJobs in Magento 1.x and Magento 2.0. Comparison

Feb 11, 2016

Before I tell you about the cron jobs in Magento 2.0, let me remind you how it can be enabled in Magento 1.x.

Magento 1.x

First of all, you need to create a module (I hope that if you are reading this article, you remember how it can be done :) ). After that you need to add the module to the config.xml file.

...
< crontab > 
        < jobs > 
            < belvg_cron > 
                < schedule >< cron_expr > * * * * *</ cron_expr ></ schedule > 
                < run >< model > mymodule / cron:: myCronFunction</ model ></ run > 
            </ belvg_cron> 
        </ jobs > 
</ crontab >
...

...

< crontab >

< jobs >

< belvg_cron >

< schedule >< cron_expr > * * * * *</ cron_expr ></ schedule >

< run >< model > mymodule / cron:: myCronFunction</ model ></ run >

</ belvg_cron>

</ jobs >

</ crontab >

...

Next step is to create a file model:

app/code/Belvg/Mymodule/Model/Cron.php.

class Belvg_Mymodule_Model_Cron
{
    public function myCronFunction()
    {
        Mage::log(‘Hello form Belvg’);
        return $this;
    }
}

class Belvg_Mymodule_Model_Cron

{

public function myCronFunction()

{

Mage::log(‘Hello form Belvg’);

return $this;

}

This task is triggered every minute and writes messages in the log.

Now I will tell you how to enable cron jobs in Magento 2.0.

How can you do it?
This is also relatively easy and can be done in 2 steps:

1. Create a file app/code/Belvg/Mymodule/etc/crontab.xml

app/code/Belvg/Mymodule/etc/ with the following content:

<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Cron:etc/crontab.xsd">
    <group id="default">
        <job name="belvg_mymodule_cron" instance="Belvg\Mymodule\Model\Cron" method="myCronFunction">
            <schedule>* * * * *</schedule>
        </job>
    </group>
</config>

</job>

</group>

</config>

2. Create a class app/code/Belvg/Mymodule/Model/Cron.php

namespace Belvg\Mymodule\Model

class Cron 
{
    protected $logger;

    public function __constructor(
        \Psr\Log\LoggerInterface $logger
        )
    {
        $this->logger = $logger;
    }

    public function myCronFunction()
    {
       $this->logger->info(‘Hello form Belvg’);
       return $this;
    }
}
