63.建立上面对应的模板文件
/resources/views/admin/user/role.blade.php

@extends('admin.base')

@section('content')
    <style>
        .layui-form-checkbox span{width: 100px}

以上则可以给用户分配角色和权限了

64.给各个功能，添加对应的权限
/routes/web.php 修改如下

// 系统管理
Route::group(['prefix' => 'admin','middleware' => ['auth','permission:system.manage']],function() {
    // 系统用户列表
    //
    //
    
});

65.添加中间件
/app/Http/Kernel.php

    protected $routeMiddleware = [
        // ....
        'role' => \Spatie\Permission\Middlewares\RoleMiddleware::class,
        'permission' => \Spatie\Permission\Middlewares\PermissionMiddleware::class,
        'role_or_permission' => \Spatie\Permission\Middlewares\RoleOrPermissionMiddleware::class,
    ];

此时可以设置用户角色，权限，功能了
