如何在Yii2中与mongodb一起使用DbQueryDependency

yii\mongodb\Query ,但我明白了:

[error][yii\base\InvalidConfigException] yii\base\InvalidConfigException: "yii\caching\DbQueryDependency::$query" should be an instance of "yii\db\QueryInterface". in /vendor/yiisoft/yii2/caching/DbQueryDependency.php:78

• Mongodb 4.0.8版
• 菲律宾比索7.2.6
• 意2.0.18
• yiisoft/yii2 mongodb 2.1.7版
• yiisoft/yii2 redis 2.0.9版

class Test extends yii\mongodb\ActiveRecord {
    // ...
    public static function findByTest($test){
        $dep = new DbQueryDependency([
            'query'=> (new Query())
                ->from('test')
                ->where(['test' => $test])
                ->orderBy(['updated_at' => -1 ])
                ->one(),
        ]);

        $cache = Yii::$app->cache;
        $key = 'test.'.$test;

        return $cache->getOrSet($key, function () use ($test) {
            return static::findOne(['test' => $test, 'status' => static::STATUS_ACTIVE]);

        }, 3600, $dep);
    }
    // ...
}

我希望yii在1小时内缓存mongodb文档,除非 updated_at yii\base\InvalidConfigExc eption: "yii\caching\DbQueryDependency::$query" should be an instance of "yii\db\QueryInterface".

我该怎么解决?谢谢您!
