Yii2 Yii::$container設定類的setter為何無效呢？

if(isset($_COOKIE['gridShowRows'])){    Yii::$container->set('yii\data\BaseDataProvider',[        'pagination'=>[            'pageSize'=>$_COOKIE['gridShowRows']        ]    ]);}

yii\data\BaseDataProvider有一個setPagination的方法。

public function setPagination($value)    {        if (is_array($value)) {            $config = ['class' => Pagination::className()];            if ($this->id !== null) {                $config['pageParam'] = $this->id . '-page';                $config['pageSizeParam'] = $this->id . '-per-page';            }            $this->_pagination = Yii::createObject(array_merge($config, $value));        } elseif ($value instanceof Pagination || $value === false) {            $this->_pagination = $value;        } else {            throw new InvalidParamException('Only Pagination instance, configuration array or false is allowed.');        }    }

設定後不起效果。

但是下面的設定卻又效果：

if(isset($_COOKIE['gridShowRows'])){    Yii::$container->set('yii\data\Pagination',[        'pageSize'=>$_COOKIE['gridShowRows']    ]);}

yii\data\Pagination有一個setPageSize的方法：

/**     * @param integer $value the number of items per page.     * @param boolean $validatePageSize whether to validate page size.     */    public function setPageSize($value, $validatePageSize = false)    {        if ($value === null) {            $this->_pageSize = null;        } else {            $value = (int) $value;            if ($validatePageSize && isset($this->pageSizeLimit[0], $this->pageSizeLimit[1]) && count($this->pageSizeLimit) === 2) {                if ($value < $this->pageSizeLimit[0]) {                    $value = $this->pageSizeLimit[0];                } elseif ($value > $this->pageSizeLimit[1]) {                    $value = $this->pageSizeLimit[1];                }            }            $this->_pageSize = $value;        }    }

回複內容：

if(isset($_COOKIE['gridShowRows'])){    Yii::$container->set('yii\data\BaseDataProvider',[        'pagination'=>[            'pageSize'=>$_COOKIE['gridShowRows']        ]    ]);}

yii\data\BaseDataProvider有一個setPagination的方法。

public function setPagination($value)    {        if (is_array($value)) {            $config = ['class' => Pagination::className()];            if ($this->id !== null) {                $config['pageParam'] = $this->id . '-page';                $config['pageSizeParam'] = $this->id . '-per-page';            }            $this->_pagination = Yii::createObject(array_merge($config, $value));        } elseif ($value instanceof Pagination || $value === false) {            $this->_pagination = $value;        } else {            throw new InvalidParamException('Only Pagination instance, configuration array or false is allowed.');        }    }
