How to store system settings in entity

Vote count:

I'm currently doing system, which settings should be editable by admin. He cannot add them, but only choose/edit from existing one.

All the backend is done in Sonata.

Settings class:

class SystemSettings
{
    /**
     * @var integer
     *
     * @ORM\Column(name="id", type="integer")
     * @ORM\Id
     * @ORM\GeneratedValue(strategy="AUTO")
     */
    private $id;

    /**
     * @ORM\Column(name="key", type="string", nullable=true)
     */
    private $key;

    /**
     * @ORM\Column(name="value", type="string", nullable=true)
     */
    private $value;
}

Problem is that I have different value types to store. I have some booleans, lists, integers, etc. For example I want to display array of languages as a list, but when it comes to "posts on page" setting, user should be able to write down any integer he wants. Is there any proper way to store it and display?
