获取最后一个插入ID ZF2

尝试获取映射程序中的最后一个插入ID我有这个代码：

        $sql = new Sql($this->dbAdapter);
        $stmt = $sql->prepareStatementForSqlObject($action);
        $result = $stmt->execute(); 
        return array('success' => $result->getAdapter()->lastInsertId());

我遇到的问题是，我得到了一个致命错误：（！）致命错误：在第100行上调用/var/www/zf sklete/module/Application/src/Application/Mapper/ZendDbSqlMapper.php中的未定义方法Zend''Db''Adapter''Driver''Pdo''Result:：getAdapter（）

虽然数据正在被添加到数据库中，但我似乎无法获得适配器。

感谢您的帮助。
