可能在OneToMany和OneToOne中使用相同的实体？

I am trying to store a number of address entities within a single customer entity.

That part is easy, as its just a simple ManyToOne/OneToMany bidirectional relationship.

Take a look at our simple code, but notice the question I am posing with the additional OneToOne association I am trying to make on Customer for primary_address

class Address
{
    /**
     * @ORM\Column 
     */
    protected $address_text;

    /**
     * @ORM\ManyToOne(targetEntity="Customer", inversedBy="addresses") 
     */
    protected $customer;
}



class Customer 
{
    /**
    * @ORM\OneToMany(targetEntity="Address", mappedBy="customer")
    */
    protected $addresses;

    /**
    * @ORM\OneToOne(targetEntity="Address")
    */
    protected $primary_address;
}

So, each Customer entity should be able to have a number of Address entities associated with it, but the Customer entity should also have just one of them be a Primary Address.

How is this possible? Are there any elegant solutions?
