使用工厂的模型中的FilesSize验证器

Question

这是我在Object\model:中的模型SiteDesign.php

namespace ObjectModel;
use ZendValidatorStringLength;
use ZendValidatorNotEmpty;
use ZendValidatorFileSize;
use ZendInputFilterFactory as InputFactory;
use ZendInputFilterInputFilter;
use ZendInputFilterInputFilterAwareInterface;
use ZendInputFilterInputFilterInterface;
class SiteDesign {
public $logo_filename;
public $background_image;
public $background_color;
public function exchangeArray($data) {
    $this->logo_filename = (isset($data['logo_filename'])) ? $data['logo_filename'] : null;
    $this->background_image = (isset($data['background_image'])) ? $data['background_image'] : null;
    $this->background_color = (isset($data['background_color'])) ? $data['background_color'] : null;
}
public function setInputFilter(InputFilterInterface $inputFilter) {
    throw new Exception('Not used');
}
public function getInputFilter() {
    if (!$this->inputFilter) {
        $inputFilter = new InputFilter();
        $factory = new InputFactory();
        $inputFilter->add($factory->createInput(array(
                    'name' => 'logo_filename',
                    'filters' => array(
                        array('name' => 'StripTags'),
                        array('name' => 'StringTrim'),
                    ),
                    'validators' => array(
                        array(
                            'name' => 'FilesSize',
                            'options' => array(
                                'max' => 4 * 1024,
                                'messages' => array(
                                    Size::TOO_BIG => 'Размерът на логото не може да надвишава 5MB.',
                                ),
                            ),
                        ),
                    ),
                )));
        $inputFilter->add($factory->createInput(array(
                    'name' => 'background_image',
                    'filters' => array(
                        array('name' => 'StripTags'),
                        array('name' => 'StringTrim'),
                    ),
                    'validators' => array(
                        array(
                            'name' => 'FilesSize',
                            'options' => array(
                                'max' => 4 * 1024,
                                'messages' => array(
                                    Size::TOO_BIG => 'Размерът на изображението за фон не може да надвишава 5MB.',
                                ),
                            ),
                        ),
                    ),
                )));
        $inputFilter->add($factory->createInput(array(
                    'name' => 'background_color',
                    'filters' => array(
                        array('name' => 'StripTags'),
                        array('name' => 'StringTrim'),
                    ),
                    'validators' => array(
                    ),
                )));
        $this->inputFilter = $inputFilter;
    }
    return $this->inputFilter;
}

}

但有一条错误消息：

Zend\ServiceManager\ServiceManager:：get无法获取或创建FilesSize的实例

那么，是否可以使用工厂直接在模型中定义FilesSize验证器？这是正确的方法吗？提前谢谢。

对于ZendValidatorValidatorPluginManager（负责按名称实例化验证器），正确的名称是`"FileSize"（其中有太多"s"）。
