## 自我解读
tp5使用的是自动注册加载机制
> 门面`facade`为容器中的类提供了一个静态调用接口，相比于传统的静态方法调用， 带来了更好的可测试性和扩展性，你可以为任何的非静态类库定义一个facade类。
>
[`interface_exists`](http://php.net/manual/zh/function.interface-exists.php) 检查接口是否已被定义
[LoggerInterface](https://segmentfault.com/a/1190000002521644) 日志接口
[implements](http://php.net/manual/zh/language.oop5.interfaces.php) 对象接口
[ArrayAccess](http://php.net/manual/zh/class.arrayaccess.php)（数组式访问）接口
`facade\Config::set(include __DIR__ . '/convention.php');` 使用配置[config](https://www.kancloud.cn/xianfang/thinkphp5/think/config.md) 来加载 `convention.php` 配置
