对不起,如果这个问题已经得到解答,我找不到任何问题.

我在Symfony2中构建这个模型:

class LogEntry {
    /**
     * @var integer $id
     *
     * @ORM\Column(name="id", type="integer")
     * @ORM\Id
     * @ORM\GeneratedValue(strategy="AUTO")
     */
    private $id;

    /**
     * @var \DateTime $log_timestamp
     *
     * @ORM\Column(name="log_timestamp", type="datetime")
     */
    private $log_timestamp;

    /**
     * @var TranslationMapping $source
     *
     * @ORM\ManyToOne(targetEntity="TranslationMapping", cascade={"persist"})
     * @ORM\JoinColumn(name="source", referencedColumnName="id")
     */
    private $source;

    /**
     * @var TranslationMapping $target
     *
     * @ORM\ManyToOne(targetEntity="TranslationMapping", cascade={"persist"})
     * @ORM\JoinColumn(name="target", referencedColumnName="id")
     */
    private $target;
...
}

使用TranslationMapping像这样:

/**
 * LogAnalyzer\Bundle\CombatLogBundle\Entity\TranslationMapping
 *
 * @ORM\Table(name="TranslationMapping", uniqueConstraints={@ORM\UniqueConstraint(name="idValue_idx", columns={"stringId", "stringValue"})})
 * @ORM\Entity
 * @ORM\HasLifecycleCallbacks()
 */ …
