一、重写容器方法：

/config/container.php

<?php
declare(strict_types=1);

//use Hyperf\Di\Container;
use Core\Common\Dependencies\Di\Container;
use Hyperf\Di\Definition\DefinitionSourceFactory;
use Hyperf\Utils\ApplicationContext;

$container = new Container((new DefinitionSourceFactory(true))());
if (! $container instanceof \Psr\Container\ContainerInterface) {
    throw new RuntimeException('The dependency injection container is invalid.');
}
return ApplicationContext::setContainer($container);

二、重写

/app/Core/Common/Dependencies/Di/Container.php

<?php
declare(strict_types=1);

/**
 * This file is part of Hyperf.
 *
 * @link     https://www.hyperf.io
 * @document https://hyperf.wiki
 * @contact  group@hyperf.io
 * @license  https://github.com/hyperf/hyperf/blob/master/LICENSE
 */
namespace Core\Common\Dependencies\Di;

class Container extends \Hyperf\Di\Container
{
    public function make(string $name, array $parameters = [])
    {
        $instance = parent::make($name, $parameters);
        if ($instance instanceof InitializeInerface) {
            $instance->initialize();
        }
        return $instance;
    }
}

三、实现重写的接口

/app/Core/Common/Dependencies/Di/Contract/InitializeInerface.php

<?php
declare(strict_types=1);

/**
 * This file is part of Hyperf.
 *
 * @link     https://www.hyperf.io
 * @document https://hyperf.wiki
 * @contact  group@hyperf.io
 * @license  https://github.com/hyperf/hyperf/blob/master/LICENSE
 */
namespace Core\Common\Dependencies\Di\Contract;

interface InitializeInerface
{
    public function initialize(): void;
}

四、在自动加载initialize()方法的类中实现此接口，即可

/app/Controller/Admin/AdminLogController.php

<?php
declare(strict_types=1);

namespace App\Controller\Admin;

use App\Controller\BaseController;
use Hyperf\HttpServer\Annotation\AutoController;
use Hyperf\HttpServer\Annotation\Middleware;
use Hyperf\HttpServer\Annotation\Middlewares;
use App\Middleware\LoginAuthMiddleware;
use App\Middleware\AdminAuthMiddleware;
use Hyperf\Di\Annotation\Inject;
use App\Models\AdminLog;
use Core\Common\Dependencies\Di\Contract\InitializeInerface;

/**
 * AdminLogController
 * 后台日志控制器
 *
 * @package App\Controller\Admin
 *
 * @AutoController(prefix="admin/admin_log")
 *
 * @Middlewares({
 *     @Middleware(LoginAuthMiddleware::class),
 *     @Middleware(AdminAuthMiddleware::class)
 * })
 */
class AdminLogController extends BaseController implements InitializeInerface
{
    use \App\Traits\Admin\Controller\Expert;
    
    /**
     *
     * @Inject()
     * @var AdminLog
     */
    private AdminLog $model;
    
    /**
     * 是否开启限制数据访问
     *
     * @var bool
     */
    protected ? bool $limitData = null;
    
    /**
     * 限制数据的条件字段
     *
     * @var string
     */
    protected string $LimitField = 'admin_id';
    
    public function initialize(): void
    {
        if ($this->limitData === null) {
            $this->limitData = in_array($this->LimitField, $this->model->getFillable());
        }
    }
}

至此，就实现了hyperf的自动加载类的方法，如果需要其他方法，只需在第三和第四步中将方法实现并在实际的类中implements即可！
