## 概述
用于定义表结构，过滤掉无效字段数据。
### 简单 demo
```
class Apple extends \EasySwoole\Spl\SplBean {
protected $name;
protected $price;
protected $number;
protected function setKeyMapping(): array
{
return ['price' => 'as'];
}
}
$apple = new Apple(['name' => 'test', 'price' => 12, 'number' => 12, 'age' => 2], true);
print_r($apple->toArray());
print_r($apple->toArrayWithMapping());
echo '---------------------------------------'.PHP_EOL;
$apple->restore(['name' => 'blank', 'price' => 12, 'number' => 12]);
print_r($apple->toArray());
print_r($apple->toArrayWithMapping());
```
## 配合 Model 使用
