如何在laravel 8中自定义默认登录错误消息

php artisan make:validator CustomLoginValidator

namespace App\Validators;

use Illuminate\Validation\ValidationException;
use Illuminate\Validation\Validator;

class CustomLoginValidator extends Validator
{
    /**
     * Get the validation error messages.
     *
     * @return array
     */
    protected function messages()
    {
        return [
            'email.required' => '自定义的邮箱字段必填错误消息',
            'password.required' => '自定义的密码字段必填错误消息',
        ];
    }
}

namespace App\Providers;

use App\Validators\CustomLoginValidator;
use Illuminate\Support\ServiceProvider;
use Illuminate\Support\Facades\Validator;

class AppServiceProvider extends ServiceProvider
{
    /**
     * Bootstrap any application services.
     *
     * @return void
     */
    public function boot()
    {
        Validator::resolver(function ($translator, $data, $rules, $messages) {
            return new CustomLoginValidator($translator, $data, $rules, $messages);
        });
    }
}

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use Illuminate\Support\Facades\Validator;

class LoginController extends Controller
{
    /**
     * Handle the login request.
     *
     * @param  \Illuminate\Http\Request  $request
     * @return \Illuminate\Http\Response
     */

            'email' => 'required|email',
            'password' => 'required',
        ]);

        if ($validator->fails()) {
            return redirect()->back()
                ->withErrors($validator)
                ->withInput();
