I've got it:

Message.php

namespace Console\Entity;

use Doctrine\Common\Collections\ArrayCollection;

/**

     * @GeneratedValue 
     * @Column(type="integer")
     */
    protected $id;

    /**
     * @Column(type="text")
     */
    protected $value;

    /**
     * @ManyToOne(targetEntity="Console\Entity\MessageType", cascade={"persist"})
     */
    protected $type;

    /**
     * @OneToMany(targetEntity="Console\Entity\UserMessage", mappedBy="message", cascade={"all"}, orphanRemoval=true)
     */
    protected $userMessages;

    /**
     * @Column(type="datetime")
     */
    protected $created;

    /**
     * @param Console\Entity\MessageType $type
     * @param string $value
     */
    public function __construct(MessageType $type, $value){
        $this->type         = $type;
        $this->value        = $value;
        $this->userMessages = new ArrayCollection();
    }

    /** @PrePersist */
    public function prePersist(){
        $this->created = new \DateTime("now");
    }

    }
