This paper provides an in-depth examination of the 'Class \'\\App\\User\' not found' error that occurs when migrating the User model from the default App namespace to the App\Models namespace in the Laravel framework. The article thoroughly analyzes the root cause of the error—Laravel's authentication system hardcodes references to App\User in the EloquentUserProvider, preventing automatic recognition of the new class path after model file relocation and namespace changes. Through a step-by-step analysis of the config/auth.php configuration file structure and the working principles of EloquentUserProvider, this paper presents a comprehensive solution: first, update the User model's namespace declaration to namespace App\Models;, then modify the model reference in auth.php to App\Models\User::class. The discussion also covers supplementary measures such as clearing configuration cache and updating Composer autoloading, ensuring developers can completely resolve compatibility issues arising from namespace changes.
