Question

How to use entity as service in doctrine (Using Symfony 2.1).

Example usage:

<?php

namespace MyNamespace;

class MyEntity
{
  protected $container = NULL;
  public function __construct($container)
  {
    $this->container = $container;
  }

  /** 
   * @ORM\PrePersist
   */
  public function() 
  {
    // Must call to container and get any parameters
    // for defaults sets entity parameters
    $this->container->get('service.name');
  }
}

As a result, I need to get access to the entire container.

An entity is a data model and should only hold data (and not have any dependencies on services). If you want to modify your model in case of a certain event (PrePersist in your case) you should look into making a Doctrine listener for that. You can inject the container when defining the listener:

services:
    my.listener:
        class: Acme\SearchBundle\Listener\YourListener
        arguments: [@your_service_dependency_or_the_container_here]
        tags:
            - { name: doctrine.event_listener, event: prePersist }
