thinkphp6.0给我们预定义了paginate分页类，帮助我们快速分页，但是thinkphp6提供的分页的样式并不是我们想要的，需要我们自己扩展分页类，看看具体如何实现吧！

首先我们去复制一份官方的写好的分页类，并在此基础上进行修改，具体的路径在vendor/topthink/think-orm/src/paginator/driver/Bootstrap.php，然后在app/common/Bootstrap.php粘贴。

修改app/provider.php服务提供者，修改默认的分页驱动为我们的驱动。

<?php
use app\ExceptionHandle;
use app\Request;
// 容器Provider定义文件
return [
    'think\Request'          => Request::class,
    'think\exception\Handle' => ExceptionHandle::class,
    'think\Paginator'    =>    'app\common\Bootstrap'
];

阅读app/common/Bootstrap.php代码，在此基础上修改。以下是官方提供的分页代码vendor/topthink/think-orm/src/paginator/driver/Bootstrap.php

例如简单修改上一页下一页为中文汉字，修改以下地方。
