您应该使用此处文档中指定的MappedBy和InversedBy：http://docs.doctrine-project.org/en/2.0.x/reference/association-mapping.html#owning-side-and-inverse-side

 /**
  * @ORM\OneToOne(targetEntity="Acme\UserBundle\Entity\Profile",        
    mappedBy="user"))
  */

和你使用的另一面：

 /**
 * @ORM\OneToOne(targetEntity="Acme\UserBundle\Entity\User", inversedBy="profile" cascade={"persist"})
 * @ORM\JoinColumn(name="user_id", referencedColumnName="id")
 */
