Typo3 子类化对外服务不起作用

我正在尝试将FileCollectionService类从第三方扩展子类化。但事实并非如此

ext\u typoscript\u setup.txt：

config.tx_extbase{
persistence{
    classes{
        SKYFILLERS\SfFilecollectionGallery\Service\FileCollectionService {
            subclasses {
                TxFileCollectionService = FalkRoeder\MyExt\Service\FileCollectionService
            }
        }

    }
}

config.tx_extbase {
    objects {
        SKYFILLERS\SfFilecollectionGallery\Service\FileCollectionService.className = FalkRoeder\MyExt\Service\FileCollectionService
    }
}

}

my FileCollectionService.php放入类/服务中

<?php
namespace FalkRoeder\MyExt\Service;

/**
 * FileCollectionService
 */
class FileCollectionService extends \SKYFILLERS\SfFilecollectionGallery\Service\FileCollectionService {

    /**
     * @return array
     */
    public function methodToOverwrite() {
    ...
    }
}

为了让它工作，我需要将以下代码添加到ext\u typoscript\u setup.txt中：

config.tx_extbase{
persistence{
    classes{
        SKYFILLERS\SfFilecollectionGallery\Service\FileCollectionService {
            subclasses {
                TxFileCollectionService = FalkRoeder\MyExt\Service\FileCollectionService
            }
        }

    }
}

config.tx_extbase {
    objects {
        SKYFILLERS\SfFilecollectionGallery\Service\FileCollectionService.className = FalkRoeder\MyExt\Service\FileCollectionService
    }
}

为了让它工作，我需要将以下代码添加到ext_typoscript_setup.txt中：

config.tx_extbase{
persistence{
    classes{
        SKYFILLERS\SfFilecollectionGallery\Service\FileCollectionService {
            subclasses {
                TxFileCollectionService = FalkRoeder\MyExt\Service\FileCollectionService
            }
        }

    }
}

config.tx_extbase {
    objects {
        SKYFILLERS\SfFilecollectionGallery\Service\FileCollectionService.className = FalkRoeder\MyExt\Service\FileCollectionService
    }
}

试着做这样的事情

config.tx_extbase{
    persistence{
        classes{
            SKYFILLERS\\SfFilecollectionGallery\\Service\\FileCollectionService {
                subclasses {
                    TxFileCollectionService = VendorName\ExtensionKey\Classes\Utility\FileCollectionService

                }
            }

        }
    }
}
