Doctrine request crash with composite key - symfony

Question

I'm facing a big problem with Doctrine when i'm requesting a table with a composite primary key referencing foreign keys.
I have a 3 entities:
Library(idLibrary,adress), Book(idBook,title,pageCount), Container(idLibrary,idBook, quantity).
Everything is generated without any errors but when i'm doing findAll() request on my Container repository my browser freezes and nothing is showed like it was stuck in a loop (there 3 rows in my Container table).
class Bibliotheque
{
/**
* #var integer
*
* #ORM\Column(name="id", type="integer")
* #ORM\Id
* #ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
/**
* #ORM\Column(name="name", type="string", length=60)
*/
private $name;
/**
* #ORM\Column(name="adress", type="string", length=60)
*/
private $adress;
}
class Conteneur
{
/**
* Many Containers have One library.
* #ORM\Id
* #ORM\OneToOne(targetEntity="Bibliotheque")
* #ORM\JoinColumn(name="libraryId", referencedColumnName="id")
*/
private $library;
/**
* One Container has One book.
* #ORM\Id
* #ORM\OneToOne(targetEntity="Livre")
* #ORM\JoinColumn(name="bookId", referencedColumnName="id")
*/
private $book;
/**
* #ORM\Column(name="quantity", type="integer")
*/
private $quantity;
}
class Livre
{
/**
* #var integer
*
* #ORM\Column(name="id", type="integer")
* #ORM\Id
* #ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
/**
* #ORM\Column(name="title", type="string", length=255)
*/
private $title;
/**
* #ORM\Column(name="pageCount", type="integer")
*/
private $pageCount;
/**
* Un livre a plusieurs auteurs
* #ORM\ManyToMany(targetEntity="Auteur")
* #ORM\JoinTable(name="books_authors",
* joinColumns={#ORM\JoinColumn(name="book_id", referencedColumnName="id")},
* inverseJoinColumns={#ORM\JoinColumn(name="author_id", referencedColumnName="id")}
* )
*/
private $authors;
}
class Auteur
{
/**
* #var integer
*
* #ORM\Column(name="id", type="integer")
* #ORM\Id
* #ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
/**
* #ORM\Column(name="name", type="string", length=60)
*/
private $name;
/**
* #ORM\Column(name="surname", type="string", length=60)
*/
private $prenom;
/**
* #ORM\Column(name="birthDate", type="date")
*/
private $birthDate;
}

Answer 1

firstly, please use only French or English for class name and variable.
Add id inside class "Container" and remove annotation #ORM\id for attributes "library" and "book"
Define attribute "authors" with ArrayCollection and add method getAuthors(), addAuthor(Author $author), removeAuthor(Author $author)
And rename the tables name => "name_id" not "nameId"
look documention http://symfony.com/doc/current/doctrine.html
class Library
{
/**
* #var integer $id
*
* #ORM\Column(name="id", type="integer")
* #ORM\Id
* #ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
/**
* #var string $name
*
* #ORM\Column(name="name", type="string", length=60)
*/
private $name;
/**

* #ORM\Column(name="address", type="string", length=60)

private $address;

*
