symfony2.0&doctrine table prefixテーブル接頭辞の設定

1.bundleの下にあるResources/config/servicesを開く.yml
2.prefixパラメータの追加、例えばデフォルトのacme

parameters:
    acmebundle.db.table_prefix: acme_

3.サービスの追加

services:
            acmebundle.tblprefix_subscriber:
                class: AcmeBundle\Subscriber\TablePrefixSubscriber
                arguments: [%mybundle.db.table_prefix%]
                tags:
                    - { name: doctrine.event_subscriber }

AcmeBundle\Subscriber\TablePrefixSubscriber.php

<?php
namespace AcmeBundle\Subscriber;
         
use Doctrine\ORM\Event\LoadClassMetadataEventArgs;
         
class TablePrefixSubscriber implements \Doctrine\Common\EventSubscriber
{
    protected $prefix = '';
 
    public function __construct($prefix)
    {
        $this->prefix = (string) $prefix;
    }
 
    public function getSubscribedEvents()
    {
        return array('loadClassMetadata');
    }
         
    public function loadClassMetadata(LoadClassMetadataEventArgs $args)
    {
        $classMetadata = $args->getClassMetadata();
 
        // Do not re-apply the prefix in an inheritance hierarchy.
        if ($classMetadata->isInheritanceTypeSingleTable() && !$classMetadata->isRootEntity()) {
            return;
        }
 
        if (FALSE !== strpos($classMetadata->namespace, 'AcmeBundle')) {
            $classMetadata->setPrimaryTable(array('name' => $this->prefix . $classMetadata->getTableName()));
 
            foreach ($classMetadata->getAssociationMappings() as $fieldName => $mapping) {
                if ($mapping['type'] == \Doctrine\ORM\Mapping\ClassMetadataInfo::MANY_TO_MANY
                  && isset($classMetadata->associationMappings[$fieldName]['joinTable']['name'])) {
                    $mappedTableName = $classMetadata->associationMappings[$fieldName]['joinTable']['name'];
                    $classMetadata->associationMappings[$fieldName]['joinTable']['name'] = $this->prefix . $mappedTableName;
                }
            }
