<?php
namespace App\Traits;

use Illuminate\Support\Str;

trait UuidTrait
{
    // permission 官方给出的 trait start
    protected static function boot()
    {
        parent::boot();

        static::creating(function ($model) {
            $model->{$model->getKeyName()} = (string)Str::uuid();

        });
    }

    public function getIncrementing()
    {
        return false;
    }

    public function getKeyType()
    {
        return 'string';
    }

}

在模型中引入trait使用

use App\Traits\UuidTrait;
class User extends Authenticatable
{
    use UuidTrait;
