Question

我正在处理捆绑软件，我需要从配置参数加载学说resolve_target_entities。

This article应该是我的解决方案，事实是，使用捆绑包似乎无法加载“编译器传递类”。

这是我的捆绑包类

class PersonalBundle extends Bundle
{
    public function build(ContainerBuilder $container){
        parent::build($container);
        $container->addCompilerPass(new ResolveTargetEntitiesPass());
    }
}

这是ResolveTargetEntitiesPass类

class ResolveTargetEntitiesPass implements CompilerPassInterface
{

    /**
     * {@inheritdoc}
     */
    public function process(ContainerBuilder $container)
    {
        // Gets the custom entity defined by the user (or the default one)
        $customEntityClass = $container->getParameter('personal.custom_class');
        // Skip the resolve_target_entities part if user has not defined a different entity
        if (DefaultClassInterface::DEFAULT_ENTITY_CLASS == $customEntityClass) {
            return;
        }
        // Throws exception if the class isn't found
        if (!class_exists($customEntityClass)) {
            throw new ClassNotFoundException(sprintf("Can't find class %s ", $customEntityClass));
        }

        // Get the doctrine ResolveTargetEntityListener
        $def = $container->findDefinition('doctrine.orm.listeners.resolve_target_entity');
        // Adds the resolve_target_enitity parameter
        $def->addMethodCall('addResolveTargetEntity', array(
            DefaultClassInterface::DEFAULT_ENTITY_CLASS, $customEntityClass, array()
        ));
        // This was added due this problem
        // https://stackoverflow.com/a/46656413/7070573
        if (version_compare(Version::VERSION, '2.5.0-DEV') < 0 && !$def->hasTag('doctrine.event_listener')) {
            $def->addTag('doctrine.event_listener', array('event' => 'loadClassMetadata'));
        } elseif (!$def->hasTag('doctrine.event_subscriber')) {
            $def->addTag('doctrine.event_subscriber');
        }
    }
}

当我使用该类时，会引发此错误

类型为“ PersonalBundle \ Entity \ DefaultClass”的期望值对于关联字段“ PersonalBundle \ Entity \ Group＃$ defaultClass”，得到改为使用“ App \ Entity \ CustomClass”。

正如我所说，似乎不加载ResolveTargetEntitiesPass ... 谢谢

所以我解决了更改编译器传递优先级的问题。我尝试将捆绑软件移至config/bundle.php的顶部，然后开始工作，然后遵循https://symfony.com/blog/new-in-symfony-3-2-compiler-passes-improvements，我保留了默认类型，但增加了优先级（从0，默认为1）。我不确定哪个服务已被“降级”，所以如果有人有想法可以欢迎。

<?php
// ...
use Symfony\Component\DependencyInjection\Compiler\PassConfig;

class PersonalBundle extends Bundle
{
    public function build(ContainerBuilder $container){
        parent::build($container);
        $container->addCompilerPass(new ResolveTargetEntitiesPass(), PassConfig::TYPE_BEFORE_OPTIMIZATION, 1);
    }
}
