Laravel 中是否可以自定义验证

我追溯了一下源码，看好像没有说可以使用自定义方法去做的，就类似于tp或者Yii的

tp
 'shop_price' => ['required', 'regex'=>'([1-9]\d*(\.\d*[1-9])?)|(0\.\d*[1-9])','checkShopPrice'],

 Yii
 public function rules()
{
  $rules = parent::rules();
  $rules[] =  [['tag_ids', 'port_ids','industry_ids','WORLD_AREA_ID','PROV_AREA_ID'], 'safe'];
  $rules[] =  [['raw_content'], 'string'];
  $rules[] =  [['industry_ids'], 'required'];
  $rules[] =  ['ONLY_WEB_NAPPINFORM' , 'validateOnlyWebApp'];

  return $rules;
}

这种形式的？
目前laravel中只有这两种方式

//方法1 控制器验证
        $this->validate($request,[
            'Student.name' => 'required|min:2|max:20',
            'Student.age' => 'required|integer',
            'Student.sex' => 'required|integer',
        ],[
            'required'=>':attribute 为必填项',
            'min' => ':attribute 长度不符合要求',
            'integer' => ':attribute 必须是一个整形',
        ],[  'Student.name' => '姓名',
            'Student.age' => '年龄',
            'Student.sex' => '性别',
        ]);

        //方法2 Validator类验证
        $validator = \Validator::make($request->input(),[
            'Student.name' => 'required|min:2|max:20',
            'Student.age' => 'required|integer',
            'Student.sex' => 'required|integer',
        ],[
            'required'=>':attribute 为必填项',
            'min' => ':attribute 长度不符合要求',
            'integer' => ':attribute 必须是一个整形',
        ],[  'Student.name' => '姓名',
            'Student.age' => '年龄',
            'Student.sex' => '性别',
        ]);
