如何重写laravel DatabaseManager方法

use Illuminate\Database\DatabaseManager as BaseDatabaseManager;

class CustomDatabaseManager extends BaseDatabaseManager
{
    /**
     * Get a database connection instance.
     *
     * @param  string  $name
     * @return \Illuminate\Database\Connection
     */
    public function connection($name = null)
    {
        // 自定义的连接逻辑
        // ...

        // 调用父类的connection方法获取连接实例
        return parent::connection($name);
    }
}

// config/database.php

return [
    // ...

    'connections' => [
        'mysql' => [
            'driver' => 'custom', // 使用自定义的数据库驱动
            'database' => env('DB_DATABASE', 'forge'),
            'username' => env('DB_USERNAME', 'forge'),
            'password' => env('DB_PASSWORD', ''),
            'charset' => 'utf8mb4',
            'collation' => 'utf8mb4_unicode_ci',
            'prefix' => '',
            'strict' => true,
            'engine' => null,
        ],
    ],

    'migrations' => 'migrations',

    // ...

    'custom' => [
        'driver' => 'mysql',
        'host' => env('DB_HOST', '127.0.0.1'),
        'port' => env('DB_PORT', '3306'),
        'database' => env('DB_DATABASE', 'forge'),
        'username' => env('DB_USERNAME', 'forge'),
        'password' => env('DB_PASSWORD', ''),
        'charset' => 'utf8mb4',
        'collation' => 'utf8mb4_unicode_ci',
        'prefix' => '',
