类错误：无法声明类

I have a simple Php Class using composer autoload. But If Try to laod the Class I have Created It Return Error Fatal error: Class 'User' not found in C:\Users\Ilamini\Desktop\xampp\htdocs\E-learning\bootstrap\boot.php on line 11

my composer.json

 "autolaod" :{
            "psr-4":{
                "App\\" : "app"
            }
        }

the class

<?php

    namespace App\Models;

    /**
    * 
    */
    class User 
    {


    }

my bootstrap

require_once INC_ROOT.'/vendor/autoload.php';
$user =new \App\Models\User;
    var_dump($user);
    die();

bUt if require the User Class with Php Require Class it Work.

require_once INC_ROOT.'/app/Models/User.php';

$user =new \App\Models\User;
var_dump($user);
die();

I Autoload with Composer But Is not working;

I miss spelt autoload in the psr-4 composer code. So it Should be

 "autoload" :{
            "psr-4":{
                "App\\" : "app"
            }
        }

You need to include composers autoload.phpfile.

You don't need to require_once INC_ROOT.'/app/Models/User.php'
